Demand

Demand (pronounced dih-mand (U) or dee–mahnd (non-U))

(1) To ask for with proper authority; claim as a right.

(2) To ask for peremptorily or urgently.

(3) To call for or require as just, proper, or necessary.

(4) In law, to lay formal claim to.

(5) In law, to summon, as to court.

(6) An urgent or pressing requirement.

(7) In economics, the desire to purchase, coupled (hopefully) with the power to do so.

(8) In economics, the quantity of goods that buyers will take at a particular price.

(9) A requisition; a legal claim.

(10) A question or inquiry (archaic).

1250-1300: From Middle English demaunden and Anglo-French demaunder, derived from the Medieval Latin dēmandāre (to demand, later to entrust) equivalent to  + mandāre (to commission, order).  The Old French was demander and, like the English, meant “to request” whereas "to ask for as a right" emerged in the early fifteenth century from Anglo-French legal use.  As used in economic theory and political economy (correlating to supply), first attested from 1776 in the writings of Adam Smith.  The word demand as used by economists is a neutral term which references only the conjunction of (1) a consumer's desire to purchase goods or services and (2) hopefully the power to do so.  However, in general use, to say that someone is "demanding" something does carry a connotation of anger, aggression or impatience.  For this reason, during the 1970s, the language of those advocating the rights of women to secure safe, lawful abortion services changed from "abortion on demand" (ie the word used as an economist might) to "pro choice".  Technical fields (notably economics) coin derived forms as they're required (counterdemand, overdemand, predemand etc).  Demand is a noun & verb, demanding is a verb & adjective, demandable is an adjective, demanded is a verb and demander is a noun; the noun plural is demands.

Video on Demand (VoD)

Directed by Tiago Mesquita with a screenplay by Mark Morgan, Among the Shadows is a thriller which straddles the genres, elements of horror and the supernatural spliced in as required.  Although in production since 2015, with the shooting in London and Rome not completed until the next year, it wasn’t until 2018 when, at the European Film Market, held in conjunction with the Internationale Filmfestspiele Berli (Berlin International Film Festival), that Tombstone Distribution listed it, the distribution rights acquired by VMI, Momentum and Entertainment One, and VMI Worldwide.  In 2019, it was released progressively on DVD and video on demand (VoD), firstly in European markets, the UK release delayed until mid-2020.  In some markets, for reasons unknown, it was released with the title The Shadow Within.

Video on Demand (VoD) and streaming services are similar concepts in video content distribution but there are differences.  VoD is a system which permits users to view content at any time, these days mostly through a device connected to the internet across IP (Internet Protocol), the selection made from a catalog or library of available titles and despite some occasionally ambiguous messaging in the advertising, the content is held on centralized servers and users can choose directly to stream or download.  The VoD services is now often a sub-set of what a platform offers which includes content which may be rented, purchased or accessed through a subscription.

Streaming is a method of delivering media content in a continuous flow over IP and is very much the product of the fast connections of the twenty-first century.  Packets are transmitted in real-time which enables users to start watching or listening without waiting for an entire file (or file set) to download, the attraction actually being it obviates the need for local storage.  There’s obviously definitional and functional overlap and while VoD can involve streaming, not all streaming services are technically VoD and streaming can also be used for live events, real-time broadcasts, or continuous playback of media without specific on-demand access. By contrast, the core purpose of VoD is to provide access at any time and streaming is a delivery mechanism, VoD a broad concept and streaming a specific method of real-time delivery as suited to live events as stored content.

The Mercedes-Benz SSKL and the Demand Supercharger

Modern rendition of Mercedes-Benz SSLK in schematic, illustrating the drilled-out chassis rails.  The title is misleading because the four or five SSKLs built were all commissioned in 1931 (although it's possible one or more used a modified chassis which had been constructed in 1929).  All SSK chassis were built between 1928-1932 although the model remained in the factory's catalogue until 1933. 

The Mercedes-Benz SSKL was one of the last of the road cars which could win top-line grand prix races.  An evolution of the earlier S, SS and SSK, the SSKL (Super Sports Kurz (short) Leicht (light)) was notable for the extensive drilling of its chassis frame to the point where it was compared to Swiss cheese; reducing weight with no loss of strength.  The SSKs and SSKLs were famous also for the banshee howl from the engine when the supercharger was running; nothing like it would be heard until the wail of the BRM V16s twenty years later.  It was called a demand supercharger because, unlike some constantly-engaged forms of forced-induction, it ran only on-demand, in the upper gears, high in the rev-range, when the throttle was pushed wide-open.  Although it could safely be used for barely a minute at a time, when running, engine power jumped from 240-odd horsepower (HP) to over 300.  The number of SSKLs built has been debated and the factory's records are incomplete because (1) like many competition departments, it produced and modified machines "as required" and wasn't much concerned about documenting the changes and (2) many archives were lost as a result of bomb damage during World War II (1939-1945); most historians suggest there were four or five SSKLs, all completed (or modified from earlier builds) in 1931.  The SSK had enjoyed great success in competition but even in its heyday was in some ways antiquated and although powerful, was very heavy, thus the expedient of the chassis-drilling intended to make it competitive for another season.  Lighter (which didn't solve but at least to a degree ameliorated the brake & tyre wear) and easier to handle than the SSK (although the higher speed brought its own problems, notably in braking), the SSKL enjoyed a long Indian summer and even on tighter circuits where its bulk meant it could be out-manoeuvred, sometimes it still prevailed by virtue of durability and sheer power.

Rudolf Caracciola (1901–1959) and SSKL in the wet, German Grand Prix, Nürburgring, 19 July, 1931.  Alfred Neubauer (1891–1980; racing manager of the Mercedes-Benz competition department 1926-1955) maintained Caracciola "...never really learned to drive but just felt it, the talent coming to him instinctively.   

Sometimes too it got lucky.  When the field assembled in 1931 for the Fünfter Großer Preis von Deutschland (fifth German Grand Prix) at the Nürburgring, even the factory acknowledged that at 1600 kg (3525 lb), the SSKLs, whatever their advantage in horsepower, stood little chance against the nimble Italian and French machines which weighed-in at some 200 KG (440 lb) less.  However, on the day there was heavy rain with most of race conducted on a soaked track and the twitchy Alfa Romeos, Maseratis and the especially skittery Bugattis proved less suited to the slippery surface than the truck-like but stable SSKL, the lead built up in the rain enough to secure victory even though the margin narrowed as the surface dried and a visible racing-line emerged.  Time and the competition had definitely caught up by 1932 however and it was no longer possible further to lighten the chassis or increase power so aerodynamics specialist Baron Reinhard von Koenig-Fachsenfeld (1899-1992) was called upon to design a streamlined body, the lines influenced both by his World War I (1914-1918 and then usually called the "World War") aeronautical experience and the "streamlined" racing cars which had been seen in the previous decade.  At the time, the country greatly was affected by economic depression which spread around the world after the 1929 Wall Street crash, compelling Mercedes-Benz to suspend the operations of its competitions department so the one-off "streamliner" was a private effort (though with some tacit factory assistance) financed by the driver (who borrowed some of the money from his mechanic!).

The streamlined SSKL crosses the finish line, Avus, 1932.

The driver was Manfred von Brauchitsch (1905-2003), nephew of Major General (later Generalfeldmarschall (Field Marshal)) Walther von Brauchitsch (1881–1948; Oberbefehlshaber (Commander-in-Chief) of OKH (Oberkommando des Heeres (the German army's high command) 1938-1941).  An imposing but ineffectual head of the army, Uncle Walther also borrowed money although rather more than loaned by his nephew's mechanic, the field marshal's funds coming from the state exchequer, "advanced" to him by Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945).  Quickly Hitler learned the easy way of keeping his mostly aristocratic generals compliant was to loan them money, give them promotions, adorn them with medals and grant them estates in the lands he'd stolen during his many invasions.  His "loans" proved good investments.  Beyond his exploits on the circuits, Manfred von Brauchitsch's other footnote in the history of the Third Reich (1933-1945) is the letter sent on April Fools' Day 1936 to Uncle Walther (apparently as a courtesy between gentlemen) by Baldur von Schirach (1907-1974; head of the Hitlerjugend (Hitler Youth) 1931-1940 & Gauleiter (district party leader) and Reichsstatthalter (Governor) of Vienna 1940-1945) claiming he given a "horse whipping" to the general's nephew because a remark the racing driver was alleged to have made about Frau von Schirach (the daughter of Hitler's court photographer!).  It does seem von Schirach did just that though it wasn't quite the honorable combat he'd claimed: in the usual Nazi manner he'd arrived at von Brauchitsch's apartment in the company of several thugs and, thus assisted, swung his leather whip.  Von Brauchitsch denied ever making the remarks.  Unlike the German treasury, the mechanic got his money back and that loan proved a good investment, coaxing from the SSKL a victory in its final fling.  Crafted in aluminum by Vetter in Cannstatt, the body was mounted on von Brauchitsch's race-car and proved its worth at the at the Avusrennen (Avus race) in May 1932; with drag reduced by a quarter, the top speed increased by some 12 mph (20 km/h) and the SSKL won its last major trophy on the unique circuit which rewarded straight-line speed like no other.  It was the last of the breed; subsequent grand prix cars would be pure racing machines with none of the compromises demanded for road-use.

Evolution of the front-engined Mercedes-Benz grand prix car, 1928-1954

1928 Mercedes-Benz SS.

As road cars, the Mercedes-Benz W06  S (1927-1928) & SS (1928-1930) borrowed unchanged what had long been the the standard German approach in many fields (foreign policy, military strategy, diplomacy, philosophy etc): robust engineering and brute force; sometimes this combination worked well, sometimes not.  Eschewing refinements in chassis engineering or body construction as practiced by the Italians or French, what the S & SS did was achieved mostly with power and the reliability for which German machinery was already renowned.  Although in tighter conditions often out-manoeuvred, on the faster circuits both were competitive and the toughness of their construction meant, especially on the rough surfaces then found on many road courses, they would outlast the nimble but fragile opposition.

1929 Mercedes-Benz SSK.

By the late 1920s it was obvious an easier path to higher performance than increasing power was to reduce the SS's (Super Sport) size and weight.  The former easily was achieved by reducing the wheelbase, creating a two-seat sports car still suitable for road and track, tighter dimensions and less bulk also reducing fuel consumption and tyre wear, both of which had plagued the big, supercharged cars.  Some engine tuning and the use of lighter body components achieved the objectives and the SSK was in its era a trophy winner in sports car events and on the grand prix circuits.  Confusingly, the "K" element in the name stood for kurz (short) and not kompressor (supercharger) as was applied to some other models although all SSKs used a supercharged, 7.1 litre (433 cubic inch) straight-six. 

1931 Mercedes-Benz SSKL.

The French, British and Italian competition however also were improving their machinery and by late 1930, on the racetracks,  the SSK was becoming something of a relic although it remained most desirable as a road car, demand quelled only by a very high price in what suddenly was a challenging economic climate.  Without the funds to create anything new and with the big engine having reached the end of its development potential, physics made obvious to the engineers more speed could be attained only through a reduction in mass so not only were body components removed or lightened where possible but the chassis and sub-frames were drilled to the point where the whole apparatus was said to resemble "a Swiss cheese".  The process was time consuming but effective because, cutting the SSK's 1600 KG heft to the SSKL's more svelte 1445 (3185), combined with the 300-odd HP which could be enjoyed for about a minute with the supercharger engaged, produced a Grand Prix winner which was competitive for a season longer than any had expected and one also took victory in the 1931 Mille Miglia.  Although it appeared in the press as early a 1932, the "SSKL" designation is retrospective, the factory's extant records listing the machines either as "SSK" or "SSK, model 1931".  No more than five were built and none survive (rumors of a frame "somewhere in Argentina" apparently an urban myth) although some SSK's were at various times "drilled out" to emulate the look and the appeal remains, a replica cobbled together from real and fabricated parts sold at auction in 2007 for over US$2 million; this was when a million dollars was still a lot of money.  

1932 Mercedes-Benz SSKL (die Gurke).

The one-off bodywork (hand beaten from aircraft-grade sheet aluminum) was fabricated for a race held at Berlin's unique Automobil-Verkehrs- und Übungsstraße (Avus; the "Automobile traffic and training road") which featured two straights each some 6 miles (10 km) in length, thus the interest in increasing top speed and while never given an official designation by the factory, the crowds dubbed it die Gurke (the cucumber).  The streamlined SSKL won the race and was the first Mercedes-Benz grand prix car to be called a Silberpfeil (silver arrow), the name coined by radio commentator Paul Laven (1902-1979) who was broadcasting trackside for Südwestdeutsche Rundfunkdienst AG (Southwest German Broadcasting Service); he was struck by the unusual appearance although the designer had been inspired by an aircraft fuselage rather than arrows or the vegetable of popular imagination.  The moniker was more flattering than the nickname Weiße Elefanten (white elephant) applied to S & SS which was a reference to their bulk and not a use of the phrase in its usual figurative sense.  The figurative sense came from the Kingdom of Siam (modern-day Thailand) where elephants were beasts of burden, put to work hauling logs in forests or carting other heavy roads but the rare white (albino) elephant was a sacred animal which could not be put to work.  However, the owner was compelled to feed and care for the unproductive creature and the upkeep of an elephant was not cheap; they have large appetites.  According to legend, if some courtier displeased the king, he could expect the present of a white elephant.  A “white elephant” is thus an unwanted possession that though a financial burden, one is “stuck with” and the term is applied the many expensive projects governments around the world seem unable to resist commissioning.

Avus circuit.  Unique in the world, it was the two long straights which determined die Gurke's emphasis on top speed.  Even the gearing was raised (ie a numerically lower differential ratio) because lower engine speeds were valued more than low-speed acceleration which was needed only once a lap.

The size of the S & SS was exaggerated by the unrelieved expanses of white paint (Germany's designated racing color) although despite what is sometimes claimed, Ettore Bugatti’s (1881–1947) famous quip “fastest trucks in the world” was his back-handed compliment not to the German cars but to W. O. Bentley’s (1888–1971) eponymous racers which he judged brutish compared to his svelte machines.  Die Gurke ended up silver only because such had been the rush to complete the build in time for the race, there was time to apply the white paint so it raced in a raw aluminum skin.  Remarkably, in full-race configuration, die Gurke was driven to Avus on public roads, a practice which in many places was tolerated as late as the 1960s.  Its job at Avus done, die Gurke was re-purposed for high-speed tyre testing (its attributes (robust, heavy and fast) ideal for the purpose) before "disappearing" during World War II.  Whether it was broken up for parts or metal re-cycling, spirted away somewhere or destroyed in a bombing raid, nobody knows although it's not impossible conventional bodywork at some point replaced the streamlined panels.  In 2019, Mercedes-Benz unveiled what it described as an "exact replica" of die Gurke, built on an original (1931) chassis.    

1934 Mercedes-Benz W25.

After building the replica Gurke, Mercedes-Benz for the first time subjected it to a wind-tunnel test, finding (broadly in line with expectations) its c(coefficient of drag) improved by about a third, recording 0.616 against a standard SSK's 0.914.  By comparison, the purpose-built W25 from 1934 delivered a 0.614 showing how effective Baron Koenig-Fachsenfeld's design had been although by today's standards, the numbers are not of shapes truly "slippery".  Although "pure" racing cars had for years existed, the W25 (Werknummer (works number) 25) was the one which set many elements is what would for a quarter-century in competition be the default template for most grand prix cars and its basic shape and configuration remains recognizable in the last front-engined car to win a Word Championship grand prix in 1960.  The W25 was made possible by generous funding from the new Nazi Party, "prestige projects" always of interest to the propaganda-minded party.  With budgets which dwarfed the competition, immediately the Mercedes-Benz and Auto Unions enjoyed success and the W25 won the newly inaugurated 1935 European Championship.  Ironically, the W25's most famous race was the 1935 German Grand Prix at the Nürburgring, won by the inspired Italian Tazio Nuvolari (1892–1953) in an out-dated and under-powered Alfa-Romeo P3, von Brauchitsch's powerful W25 shredding a rear tyre on the final lap.  However, the Auto Union's chassis design fundamentally was more farsighted; outstanding though the engine was, the W25's platform was, in many ways, eine bessere Gurke (a better cucumber) and because its limitations were inherent, the factory "sat out" most of the 1936 season to develop the W125.

1937 Mercedes-Benz W125.

Along with the dramatic, mid-engined,  V16 Auto Union Type C, the W125 was the most charismatic race car of the "golden age" of 1930s European circuit racing.  When tuned for use on the fastest circuits, the 5.7 litre (346 cubic inch) straight-eight generated over 640 HP and in grand prix racing that number would not be exceeded until the turbocharged engines (first seen in 1977) of the 1980s.  The W125 used a developed version of the W25's 3.4 (205) & 4.3 (262) straight-eights and the factory had assumed this soon would be out-performed by Auto Union's V16s but so successful did the big-bore eight prove the the Mercedes-Benz V16 project was aborted, meaning resources didn't need to be devoted to the body and chassis engineering which would have been required to accommodate the bigger, wider and heavier unit (something which is subsequent decades would doom a Maserati V12 and Porsche's Flat-16.  The W125 was the classic machine of the pre-war "big horsepower" era and if a car travelling at 100 mph (160 km/h) passed a W125 at standstill, the latter could accelerate and pass that car within a mile (1.6 km).


A W125 on the banked Nordschleife (northern ribbon (curve)) at Avus, 1937.  At Avus, the streamlined bodywork was fitted because a track which is 20 km (12 miles) in length but has only four curves puts an untypical premium on top-speed.  The banked turn was demolished in 1967 because increased traffic volumes meant an intersection was needed under the Funkturm (radio tower), tower and today only fragments of the original circuit remain although the lovely art deco race control tower still exists and was for a time used as restaurant.  Atop now sits a Mercedes-Benz three-pointed star rather than the swastika which flew in 1937. 

1938 Mercedes-Benz W154.

On the fastest circuits the streamlined versions of the W125s were geared to attain 330 km/h (205 mph) and 306 km/h (190 mph) often was attained in racing trim.  With streamlined bodywork, there was also the Rekordwagen built for straight-line speed record attempts and one set a mark of 432.7 km/h (268.9 mph), a public-road world speed record that stood until 2017.  Noting the speeds and aware the cars were already too fast for circuits which had been designed for, at most, velocities sometimes 100 km/h (50 mph) less, the governing body changed the rules, limiting the displacement for supercharged machines to 3.0 litres (183 cubic inch), imagining that would slow the pace.  Fast though the rule-makers were, the engineers were quicker still and it wasn't long before the V12 W154 was posting lap-times on a par with the W125 although they did knock a few km/h off the top speeds.  The rule change proved as ineffective in limiting speed as the earlier 750 KG formula which had spawned the W25 & W125.

1939 Mercedes-Benz W165.

An exquisite one-off, the factory built three W165s for the single purpose of contesting the 1939 Tripoli Grand Prix.  Remarkable as it may now sound, there used to be grand prix events in Libya, then a part of Italy's colonial empire.  Anguished at having for years watched the once dominant Alfa Romeos enjoy only the odd (though famous) victory as the German steamroller flattened all competition (something of a harbinger of the Wehrmacht's military successes in 1939-1940), the Italian authorities waited until the last moment before publishing the event's rules, stipulating the use of a voiturette (small car) with a maximum displacement of 1.5 litres  (92 cubic inch).  The rules were designed to suit the Alfa Romeo 158 (Alfetta) and Rome was confident the Germans would have no time to assemble such a machine.  However, knowing Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945), still resenting what happened at the Nürburgring in 1935, would not be best pleased were his Axis partner (and vassal) Benito Mussolini (1883-1945; Duce (leader) & Prime-Minister of Italy 1922-1943) to enjoy even this small victory, the factory scrambled and conjured up the V8-powered (a first for Mercedes-Benz) W165, the trio delivering a "trademark 1-2-3" finish in Tripoli.  As a consolation, with Mercedes-Benz busy building inverted V12s for the Luftwaffe's Messerschmitts, Heinkels and such, an Alfa Romeo won the 1940 Tripoli Grand Prix which would prove the city's last.      
 
1954 Mercedes Benz W196R Strómlinienwagen (literally "streamlined car" but translated usually as "Streamliner".

A curious mix of old (drum brakes, straight-eight engine and swing axles) and new (a desmodromic valve train, fuel injection and aerodynamics developed in a wind-tunnel with the help of engineers then banned from being involved in aviation), the intricacies beneath the skin variously bemused or delighted those who later would come to be called nerds but it was the sensuous curves which attracted most publicity.  Strange though it appeared, it was within the rules and clearly helped deliver stunning speed although the pace did expose some early frailty in road-holding (engineers have since concluded the thing was a generation ahead of tyre technology).  It was one of the prettiest grand prix cars of the post war years and the shape (sometimes called "type Monza", a reference to the Italian circuit with long straights so suited to it) would later much appeal to pop-artist Andy Warhol (1928–1987) who used it in a number of prints.

1954 Mercedes-Benz W196R.  In an indication of how progress accelerated after 1960, compare this W196R with (1) the W25 of 20 years earlier and (2) any grand prix car from 1974, 20 years later. 

However, although pleasing to the eye, the W196R Strómlinienwagen was challenging even for expert drivers and it really was a machine which deserved a de Dion rear suspension rather than the swing axles (on road cars the factory was still building a handful with these as late as 1981 and their fudge of semi-trailing rear arms (the "swing axle when you're not having a swing axle") lasted even longer).  Of more immediate concern to the drivers than any sudden transition to oversteer was that the aluminium skin meant they couldn't see the front wheels so, from their location in the cockpit, it was difficult to judge the position of the extremities, vital in a sport where margins can be fractions of a inch.  After the cars in 1954 returned to Stuttgart having clouted empty oil drums (those and bails of hay was how circuity safety was then done) during an unsuccessful outing to the British Grand Prix at Silverstone, a conventional body quickly was crafted and although visually unremarkable, the drivers found it easier to manage and henceforth, the Strómlinienwagen appeared only at Monza.  There was in 1954-1955 no constructor's championship but had there been the W196R would in both years have won and it delivered two successive world driver's championships for Juan Manuel Fangio (1911–1995).  Because of rule changes, the three victories by the W196R Strómlinienwagen remain the only ones in the Formula One World Championship (since 1950) by a car with enveloping bodywork.

1807: Apparently a creation of US English meaning “sauce, gravy; any thick liquid”, from the Dutch (dialectical) doop (thick dipping sauce), a derivative of dopen or doopen (to dip, baptize; deep), from the Middle Dutch dopen, from the Old Dutch dōpen, from the Frankish daupijan, from the Proto-Germanic daupijaną.  By extension, by the late nineteenth century it came generally to be used of any mixture or preparation of unknown ingredients producing a thick liquid.  The use of doop in the sense “narcotic drug” was derived ultimately from the viscous opium juice (the drug of choice of the well-connected in Ancient Greece) but in English was in use by at least 1899 and came from the smoking of semi-liquid opium preparations.  The verb use in the sense of “administer a drug to” appeared in print in 1889.  The idea of “insider information” was in use by at least 1901 and is thought to come from the knowledge of knowing which horse in a race had been doped (thus predicting it would run faster or slower than its form would suggest), this sense dating from 1900.  From this idea (inside information) developed the US slang “to dope out” (figure out, clarify).    The sense of “an unintelligent person” may have been used as early as the 1840s and came from the stupefying effects of opium, those intoxicated displaying obvious impaired cognitive facilities.  The word was related to the English dip and the German taufen (to baptize) but not to dopamine which came from chemistry, the construct being (DOPA (dihydroxyphenylalanine) +‎ -amine.

Unlike some constructions in English (eg domelessness (absence of a dome) or the informal gaynessness (“excessive” gayness)), there seems no recorded use of dopnessness.  For the commoly used “dopey”, the comparative is dopier and the superlative dopiest.  The use of “doper” to describe both: (1) someone who administers dope and (2) someone to whom dope is administered differs from the convention used in many words in English (eg payer vs payee) so the non-standard noun dopee can also be a synonym of doper.  Presumably, a useful distinction would be a dopee being one whose dope has been administered by another while a doper is one who self-administers.  Dope is a noun, verb & adjective, dopiness & dopeness are nouns, doper is a noun & adjective, doping is a noun & verb, doped is a verb & adjective and dopey (sometimes spelled dopy (the derived forms following this)) dopier & dopiest are adjectives, the noun plural is dopes.  Acronymfinder list eleven DOPEs, only two of which are narcotic related.

The use by the New York Yankees MLB (Major League Baseball) franchise seems daring given the existence of the Independent Program Administrator (IPA) of the Joint Drug Prevention and Treatment Program (JBTPT) which monitors the use of PEDs in the sport.  The JBTPT jointly is run by the MLB and the MLBPA (Major League Baseball Players Association) and the IPA oversees all drug testing, collection and enforcement.  Pleasingly, the JBTPB often is referred to as the “Major League Joint Drug Program”.

Dilbert cartoon by Scott Adams, published in 1995 on Bastille Day (14 July). 

First published in 1989, the once widely-syndicated "corporate life" Dilbert cartoon strip dealt with engineers, programmers and such working in a corporation run by those without a technical background, the exemplar of the latter being the “pointy haired boss”.  The cartoon was the work of Scott Adams (b 1957) who in 2023 was “cancelled” after posting a video in which he called “Black Americans”, critical of the slogan “It's okay to be white” because of its association with white supremacist ideology, a “hate group”, suggesting “White Americans” should “get the hell away from” them.  Mr Adams later disavowed racism and moved his output on-line.

On the Dilbert website, Mr Adams stated: “No news about public figures is ever true and in context” and explained his cancellation thus: “If you believe the news, it was because I am a big ol' racist.  Fleshing that out, he added: “If you look into the context, the point that got me cancelled is that CRT [Critical Race Theory], DEI [Diversity, Equity & Inclusion] and ESG [Environmental, Social and Governance] all have in common the framing that White Americans are historically the oppressors and Black Americans have been oppressed, and it continues to this day.  I recommended staying away from any group of Americans that identifies your group as the bad guys, because that puts a target on your back.  I was speaking hyperbolically, of course, because we Americans don't have an option of staying away from each other. But it did get a lot of attention, as I hoped.  (More than I planned, actually).  Dlibert devotees prepared to separate art from artist were advised: “Disgraced and canceled cartoonist Scott Adams has moved his work and upgraded it to a spicier version entitled Dilbert Reborn.

A "Dope Mobile Bookstore" is scheduled to go on-line in December 2025 and there really was briefly a "Dope Mobile" (left) which was an on-line store for mobile phone accessories and should not be confused with a "dopemobile" which is a "dope dealer's" car.  Especially in black, a Chrysler 300 (2005-2023) is almost a cliché as a dopemobile and this 2009 model (on flatbed truck, right) was seized by New Zealand police from the estate of a deceased "dope dealer" (a profession with an unusually high death rate).  The informal term "dopemoble" can mean either (1) a vehicle in which a "dope dealer" transacts "dope deals" or (2) a vehicle believed or proved to have been purchased using the proceeds of "dope dealing".  

Purple Haze, Blue Cheese and more.  The proprietors of Amsterdam’s coffee shops have always come up evocative and fanciful names for dope.  One has to have the coffee one drinks and one has to have the weed one smokes.

In derived terms and idiomatic use, “dope” appears often but because of the dual meaning (narcotics and a varnish-like substance), the same term can mean very different things so context must be noted when assessing a meaning.  A “dope stick” (also as dopestick) can describe (1) a stick or applicator for spreading dope (a viscous liquid or paste used in preparing a surface) on a surface or, in slang (2) a cigar or cigarette, (3) a pipe, (4) a marijuana joint or something similar laced with cocaine or other drug or (5) a penis suffering from priapism (a condition in which the erect penis does not return to its flaccid state despite the absence of both physical and psychological stimulation) as a result of the use of cocaine or heroin.  The condition may sound desirable but is both potentially painful and risks long-term tissue damage.

“Dope dick” (impotence induced by heavy drinking or other substance abuse) is a synonym of other slang forms including “coke dick”, “crystal dick”, “whisky dick” & “brewer's droop”.  A “dope whore” is someone addicted to narcotics who finances the habit through prostitution, the synonyms being “coke whore”, “smack slut”, “crack whore” etc.  To “smoke one's own dope” means “to believe one’s own publicity, propaganda, lies or posturing; the synonym is “to drink one's own Kool-Aid”.  For those who like to make such connections, Kool-Aid is the official soft-drink of the US state of Nebraska, otherwise famous only for being the home of billionaire investor Warren Buffett (b 1930).  To “dope out” means “to figure out, to find out, find, decipher”, something Mr Buffet certainly did of investing for profit although wryly, he notes that often when folk ask him the “secret of his success” and he tells them how his strategy worked over decades, there’s an obvious sense of disappointment because what people really want to know is “how can I get rich overnight?  He assures all he doesn’t “have the dope” on that.

Punters dope sheet (form guide), 2024 Melbourne Cup.

A “dope sheet” is a summary (ordinarily in the form of a codified, printed or digital document), containing salient facts and background information concerning a person, activity, or other subject matter.  The origin is thought to be the publications associated with horse racing (the name derived from the suspicion the most accurate indicator of a horse’s performance was whether or not it had been doped with some substance to make it run faster or slower) in which was summarized information about the horses running in certain races.  Such publications are now known variously as scratch sheets, tip sheets, firm guides, best bets etc.  Beyond gambling, “dope sheets” (a term which became misleading because some publications could be quite thick volumes) came to be used in fields as varied as automotive repair and especially in photography, film & animation; in the latter were listed the designer’s detailed instructions for artists & editors (known also as an “exposure sheet”).

Lindsay Lohan gives CNN the dope on dope use during her "troubled starlet" phase.

In the world of narcotics users (there really are many quite separate populations in “doperdom”) dope is sold by a “dope dealer”, “dope-runner”, “dope-pedlar”, “dope-pusher”, “dope-seller” or “dope-man”, sometimes from a “dope-house” whereas a “dopester” is a “street-level” trader who may be operating independently but is typically an agent on commission (paid sometimes “in kind”) and often operating from a "dopemobile").  Both retailers sell to “dope fiends”, “dope chicks”, “dope heads” etc (those who variously use or abuse) while a “dope dog” is a canine used by law enforcement officers to “sniff-out” dope.  The “dope house” must however not be confused with the “dope-shop” which was the part of the factory (typically one manufacturing aircraft) where dope was applied to the fabric laid over the spars of an airframe.  In the “dope house” was employed the “doper” who applied the dope to the fabric (dated) and again the meaning is shared with those involved with narcotics or PEDs.  If the “dope deal” couldn't for whatever reason be executed, the customer was left “dopeless” and those who over-consume could become “dope sick” (in withdrawal from “dope use”) which is different from the potentially fatal “dope overdose”.  “Dope time” & “doper time” both reference the way one’s perception of the passing of time changes when one is under the influence of narcotics.  It’s along the lines of “country mile” (typically somewhat longer than 1760 yards) or “Microsoft minutes” (referencing the dialog boxes which appeared in MS-Windows during certain operations saying something like “17 minutes remaining” which could mean anything from a few seconds to many hours).

The title's play on words is this being “the dope” on “the dope trade” out of Mexico.  In the well-populated sub-culture of narcotics use (illicit and not), there exists a bewildering array of names, vernacular and slang, some now registered trade-marks as many jurisdictions have relaxed the prohibition on “soft drugs’ but “dope” remains the most useful generic “cover-all” term.  Nor is the use of “dope” as a generic new, Lord Moran (Charles Wilson, 1882-1977; president of the Royal College of Physicians 1941-1949, personal physician (1940-1965) to Winston Churchill (1875-1965; UK prime-minister 1940-1945 & 1951-1955) in his diary (Churchill taken from the Diaries of Lord Moran: The Struggle for Survival, 1940–1965 (1966)) noting on 2 December 1952, during a trans-Atlantic flight:

This may be my last journey with Winston.  We began life humbly enough, in an unheated Lancaster bomber, and end it, twelve years later, in high state in the strato-cruiser Canopus. Messages no longer pass to the captain asking at what height we are flying; 18,000 feet or 11,000 feet (both were recorded last night), it is all one to us, pressurized at 5,000 feet.  Most of the seniors and quite a number of the juniors came to me last night for sleeping pills - this weak kneed generation that needs dope for a few hours in the air.

Lord Moran was of course well-acquainted with dope, having for years suppled Churchill with “downers” (barbiturates) to help him sleep and “uppers” (amphetamines, then commonly called “pep pills”) to perk him up, Churchill ignoring the apothecary’s descriptions and dubbing the various tablets with terms from his own ad-hoc pharmacological vocabulary including “Lord Morans”, “majors”, “minors”, “reds”, “greens”, “babies” and “midgets, all based either on the pill’s appearance or its potency, the latter established empirically.   In fairness to the Lord Moran's doped airline passengers, with a cruising speed (depending on conditions) between 300–340 mph (480–550 km/h), trans-Atlantic flight time for the Boeing 377 Stratocruiser was typically 10 hours (eastbound) to 11-12 hours (westbound), a duration compelling until the new generation of jetliners cut the trip to 6–7 hours.  A civilian version of the C-97 Stratofreighter military heavy-transporter (developed from the B-29 Superfortress heavy bomber), the Stratocruiser was, when its first test-flight was undertaken in 1947, the world biggest airliner and could carry up to 100 passengers in a multi-deck configuration although most were configured for fewer and outfitted with the luxuries which appealed to the demographic then able to afford to travel by air.  Very modern when first it flew, there were no "doped fabric" surfaces on the Stratocruiser, the fuselage, wings and tail made almost wholly from an aluminum alloy (mostly duralumin); it was thus, in the parlance of the day, an "all metal" craft.  However, despite extensive development, the problems with the 28-cylinder Pratt & Whitney radial engines were never wholly resolved and while they came to be practical for military use, they remained maintenance-intensive so operating costs were high and between 1949-1963 only 55 Stratocruisers were ever in service.

“Pipe dope”, despite the name, is not used of the drug-smoking devices and refers to any of the many lubricants and sealants used to make a pipe thread joint leak-proof and pressure-tight.  In US military slang, a “scope dope” was the officer responsible for radar or a radar operator.  The technical terms “photodope”, “photodoping” & “photodoped” come from materials science and described the process of removing a dopant (a substance added in small amounts to a pure material, such as semiconductor, to alter its original electrical or optical properties).  In electronics, impurities are added to semiconductors as a way of (1) producing a desired result or (2) modifying its properties.  In the tuning of stringed musical instruments, “peg dope” is a substance used to lubricate the pegs of an instrument and to provide the desired friction between pegs and strings.  Use seems not to have extended to other fields but conceivably it could be a helpful (and even lucrative) product for those who enjoy the sexual practice of “pegging” (women using “strap-ons”) an activity Urban Dictionary’s contributors gleefully detail, there being many nuances in use.

Automotive Digest's Dope-Master (1948, left and 1951, right).

Annually updated, Automotive Digest for years published their "Dope Masters", containing the specifications and information (ie "all the dope") required to service or "tune up" most of the automobiles sold in the US.  They were valued by mechanics but also used by many owners, cars then being mostly mechanical devices with some wiring so servicing at home with basis tools was possible in a way unthinkable with modern machines with their high electronic and software content.  In boxing, the phrase “rope-a-dope” described a technique in which the boxer assumes a defensive stance against the ropes, absorbing an opponent's blows, hoping to exploit eventual tiredness or a mistake.  Figuratively, use can be extended to any strategy in which a seemingly losing position is maintained to “lull an opponent into a false sense of security” in the hope of securing eventual victory; in the vernacular, it’s to exhaust them by “stringing them along”.  “Dope slap” is a jocular term which describes “a light slap to the back of the head”, used as a disciplinary measure for some minor infraction (ie imposed for someone being "a bit dopey") while a more severe corporal punishment would be imposed for a more a serious offence.  “Dope glass” (a synonym of “carnival glass”) was a type of glassware dating from the early twentieth century, notable for possessing lustrous colors.  Known variously as “aurora glass”, “iridescent ware”, “Iridill” “poor man's Tiffany”, “rainbow glass” & “taffeta glass”, it was initially declared by the style police to be attractive but, cheap and mass-produced, it soon came to be used to make objects judged “not in the best taste” and, being much associated with the Great Depression years of the 1930s (it was dubbed also “depression glass”), it became unfashionable.

Pre 900: From the Middle English lepen, from the Old English hlēapan, from the Proto-West Germanic hlaupan, from the Proto-Germanic hlaupaną (a doublet of lope, lowp, elope, gallop, galop, interlope and loop).  It was cognate with the German laufen (to run; to walk), the Old Norse hlaupa the Gothic hlaupan, the West Frisian ljeppe (to jump), the Dutch lopen (to run; to walk), the Danish løbe and the Norwegian Bokmål løpe, from the primitive Indo-European klewb- (to spring; stumble) (and may be compared with the Lithuanian šlùbti (to become lame) & klùbti (to stumble).  The verb forms are tangled things.  The third-person singular simple present tense is leaps, the present participle leaping, the simple past leaped or leapt (lept & lope the archaic forms) and the past participle is leaped or leapt or (lept & lopen the archaic forms).  That leapt and leaped remain in concurrent use is another of those annoy things in English which are hangovers from their ancient entrenchments in regional use and, as a general principle leapt tends to be is preferred educated British English while leaped is seen more frequently in North America (although leapt is in those places not uncommon, especially in areas with historical ties to England).  The transitive sense as in “pass over by leaping” was in use by the early fifteenth century and there are references to the children’s game “leap-frog” documented in the 1590s, and so obvious was the use of that figuratively it probably quickly was adopted but the first attested entry dates from 1704.  The familiar “to leap tall buildings in a single bound” comes from the Superman comics of the 1940s although in idiomatic use, “leaps” has been paired with “bounds” since at least since 1720.  Leap is a noun, verb & adjective, leaper & leapling are nouns and leaping and leapt & leaped are verbs; the noun plural is leaps.

The leap year is “a year containing 366 days” and use dates from late fourteenth century Middle English lepe gere, a genuine innovation because no equivalent term existed in the Old English. The origin is thought to come from the effect of fixed festival days, which normally advance one weekday per year, to “leap” ahead one day in the week.  The Medieval Latin was saltus lunae (omission of one day in the lunar calendar every 19 years), the Old English form being monan hlyp.  The adjustments happened in the calendars of many cultures, always with the purpose of ensuring the man-made devices for tracking dates (and therefore time) remained consistent with the sun; summer needed always to feel like summer and winter like winter.  Different methods of handling the intercalary were adopted and in England the bissextile was the device.  The noun & adjective bissextile (plural bissextiles) dates from the early 1580s and was from the Latin bisextilis annus (bissextile year), the construct being bisextus + -ilis, deconstructed as bis- (two; twice; doubled) + sextus (sixth) + dies (day) and was a reference to the Julian calendar's original reckoning of its quadrennial intercalary day as a 48-hour 24 February (subsequently distinguished as the two separate days of the sixth day before the March calends (sexto Kalendas Martii) and the “doubled sixth day”.  In modern use, 24 February is now understood as “five days before 1 March” but in Roman use it was called “the sixth” because the counting of dates was then inclusive.

The most physically demanding (and dangerous) part of Lindsay Lohan’s impressive leap into a Triumph TR4 in Irish Wish was undertaken by a body double (the young lady in this case deserving the “stunt-double” title).

Ready to leap: Lindsay Lohan with stunt double Aoife Bailey (b 1999).

Lindsay Lohan's Netflix movie Irish Wish (2024) was said by Irish reviewers to be "a mix of Leap Year meets Just My Luck meets Freaky Friday in which Lohan stars as quiet book editor Maddie Kelly, who embarks on a journey to find love by learning to love herself first."  Like Irish Wish, Leap Year (2010) was filmed in Ireland but unlike 2010, 2024 was a leap year.  IMCDB’s (Internet Movie Cars Database) comprehensive site confirmed the Triumph TR4 was registered in Ireland (ZV5660, VIN:STC65CT17130C) as running the 2.1 litre version (17130C) of the engine.  The Triumph 2.1 is sometimes listed as a 2.2 because, despite an actual displacement of 2138 cm3; in some places the math orthodoxy is ignored and a "round up" rule applied, something done usually in jurisdictions which use displacement-based taxation or registration regimes, the "rounding up" sometimes having the effect of "pushing" a vehicle into a category which attracts a higher rate.  Those buying a TR4 for use in competitions with a 2.0 litre limit could specify the smaller unit from the factory but being based on a tractor engine (!) and thus fitted with wet-cylinder liners, “sleeving” a 2.1 back to 2.0 wasn’t difficult.  The lack of the "IRS" (independent rear suspension) badge on the trunk (boot) lid indicates the use of the live rear axle and that detail was of no significance in the plot although, given the leap scene, a convertible of some sort would have been required.  Although on the road the IRS delivered a smoother ride, those using TR4s in competition usually preferred the live rear-axle because it made the car easier to steer “with the throttle”.

The replacement of the bissextile by the then novel 29 February every four years-odd appears such an obviously good idea it seems strange it took centuries universally to be adopted in England although the documents reveal the shift was certainly well in progress by the mid-fifteenth century and in an echo of later practices, the more curmudgeonly the institution, the slower the intrusion of the new ways, the Admiralty and houses of parliament ignoring 29 February until well into the 1500s.  It wasn’t until the Calendar (New Style) Act (1750) passed into law that 29 February received formal recognition in UK law.  The reform worked well from the start but in some jurisdictions, government lawyers took no chances and for the handful of souls born on a 29 February, their birth dates were deemed to be 28 February or 1 March for all legal purposes (eligibility for drivers licenses or pensions, age of consent etc).  One born on 29 February is a “leapling” and there are said to be a few as five million of these lonely souls on the whole planet.  In many countries hospitals and midwives note the frequency with which expectant mothers approaching March request staff do whatever is required to avoid them giving birth to a leapling, fearing the child will feel deprived by having fewer birthdays than their siblings of friends.  The math of the leap year is it is one (1) evenly divisible by 4, (2) except for years are evenly divisible by 100 except that (3) years evenly divisible by 400 are leap years.  So, 2000 was while 1900 was not; 2100 will not be a leap year, but 2400 will be.  However, because the rotation of the Earth is changing (and thus the length of days), as is its distance from the Sun, even a 29 February now and then is not enough to keep everything in sync.  So, there are also leap seconds, spliced in as needed and unlike 29 February, only those dealing with atomic clocks and such notice addition.

Leap is common in idiomatic use:  To do something in “leaps and bounds” suggests commendably quick progress.  A “leap in the dark” is to take some action while being uncertain of consequences and the related “leap of faith” is trusting in something that cannot be seen or proven so in a sense they’re two ways of saying much the same thing although “leap of faith” does also imply some trust in something or someone.  To have one’s heart “leap into one’s throat” is an allusion to the sensation felt sometimes in the throat when something scary happens.  To “leap for joy” is much the same as “jump for joy” and describes joyous happiness.  To “leap at” something is enthusiastically to take up an offer, avail one’s self of an opportunity etc.  When doing so, one might be said to “leap into action”.  To be cautioned to “look before you leap” is to suggest one should be sure of things before doing something; if one ignores the advice then it’s a “leap of faith” or a “leap into the dark”.  To “leapfrog” is to skip a step in some process, the connotation almost always positive.  To suggest someone “take a flying leap” is much the same as telling them to “go jump in the lake” or, as is now more common: “fuck off”.  The concept of the "quantum leap" was in 1913 introduced (as the "quantum jump") by Danish physicist Niels Bohr (1885–1962) in his "Bohr model" of the atom.  In the strange world of quantum mechanics it describes the discontinuous change of the state of an electron in an atom or molecule from one energy level to another and was adopted figuratively to refer to an "abrupt, extreme change".  In modern use, it has come to mean a large or transformative change, a use to which pedants sometimes object but this is how the English language works.  The “leap year bug” is jargon rather than a idiom and describes the growing number of instances of problems caused by computers (and related machines) for whatever reason not correctly handling the existence of leap years.  Most are caused by human error and some are not being rectified because the original error has been built upon to such an extent that it’s easier to handle the bugs as they occur.  If something is said to be “a bit of a leap” or “quite a leap” it means there's some scepticism about the relationship one thing and another (often cause & effect). 

Jaguar's Leaper

The radiator cap of course began as a mere functional device which could be unscrewed to allow coolant to be added but, inevitably, possibilities occurred to stylists (they weren’t yet “designers”) and soon the things were a small platform for miniature (though many were anything but small) works of art to covey an image to suit at least what was imagined to be the character of the vehicle on which they sat.  Although such embellishments are now remembered for their decorative qualities (and many in the art deco era during the inter-war were lovely creations), some genuinely were functional and “topping-up” the coolant was for decades a frequent part of the motoring experience so, however attractive they may have been, their use as a handle means they may be thought architectonic as well as artistic. The Jaguar Leaper had fangs and while that sounds ominous for pedestrians, some of the radiator cap & hood emblems looked more lethal still and even before the “safety movement” of the 1960s, there had been discussions about the dangers they posed.  For the safety of pedestrians, the few survivors now are spring-loaded or retract when the vehicle is in motion.

Leaper on 1960 Jaguar Mark 2 3.8.  Owners found the fitting handy when opening the hood.

Leaper” really was the factory’s name for the lunging feline figure which for decades adorned the space atop or behind the grill on many Jaguars.  The story of the origin is murky and while there may be some myth-making in it, the most likely explanation seems to be that when late in 1934 newly appointed Ernest William "Bill" Rankin (1898-1966, Advertising Manager and Public Relations Officer, Jaguar Cars 1934-1966) settled (from a list of charismatic wild animals) on “Jaguar” as a name for a new “sporty” SS (then the company name) car and, part of the “brand identity” was to design an appropriate radiator cap ornament.  Rankin was acquainted with the draftsman & technical illustrator Gordon Crosby (1885–1943) who he knew to be an amateur sculptor and it was to him the commission was granted.  Crosby delivered a prototype cast in bronze and according to company mythology, Jaguar’s founder, Sir William Lyons (1901–1985) thought it looked like “a cat shot off a fence” but liked the concept so, lengthened and softened into something sleeker, the refined shape emerged as the “Leaper”, first fitted in 1938.  The tales do differ, some suggesting Sir William’s “cat shot off a fence” thoughts were prompted by the sight of an earlier, third–party ornament which inspired him to task Mr Rankin with finding a replacement and, in the absence of documentary proof, Jaguar fans can pick the story they prefer.

Leaper on 1950 Jaguar Mark V 3.5.  The Mark V (1948-1951) was the last Jaguar with the external radiator cap and thus the last time a Leaper was also a cap-handle.

The SS name came from the Swallow Sidecar Company which Lyons had in 1922 co-founded with William Walmsley (1892–1961), reorganized as “S.S. Cars” after 1934 when Walmsley withdrew and the adoption in 1935 of “Jaguar” as a model name was mere marketing and nothing to do with the by then unsavoury reputation of the German SS (Schutzstaffel (protection squad), which began in 1923 as a small security guard for Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) but which evolved into a kind of parallel army for the Nazi Party and later into an armed formation almost a million-strong).  Even by 1945 when motor vehicle production resumed and the corporate name S.S. Cars formerly was changed to “Jaguar Cars Limited”, the rationale was the stronger brand identity of the latter rather than an aversion to anything associative with the Nazis.  Indeed, in 1957 Jaguar returned to SS as designation with the release of the XKSS, a road-going version of the Le Mans-winning D-Type race car.

An early Leaper (left) and the later "in flight" version (right) with the fully extended hind legs.

First fitted to production SS Jaguars in 1938, it became standard equipment on all until 1951 when the Mark V was discontinued.  As the last Jaguar to feature an external radiator cap, the assumption was that was the end of the Leaper and the strikingly modernist XK120 which created a sensation at the 1948 London Motor Show had only a radiator grill; the spirit of the age was that the ornaments were antiquated relics.  However, elsewhere in the industry, modernity and nostalgia managed peacefully to co-exist and while there was no revival of external radiator caps, the ornaments refused to die and from expensive Mercedes-Benz and Rolls-Royce to the most humble Austins and Chevrolets, the chromed constructions continued and sometimes grew, those not able to sit atop grills (many now with no “top” as such) re-imagined as hood (bonnet) ornaments.  So, in 1955 the Jaguar Leaper made a comeback on the new small saloon (the 2.4), the mascot using the subtle post-war re-working of the hind legs, made more outstretched to suggest the big cat in “mid-leap”, about to take its prey.

Rendered usually in fibreglass anodized with a shiny silver finish (although some, daringly, were gloss black), large leapers were often a feature of Jaguar dealerships (left).  Once decommissioned, they were sometimes sold and, applying dreadful and indefensible gender stereotyping, were a good gift for the garden (right) of the Jaguar-owning husband or boyfriend who "has everything". 

On the saloons, the design lasted 14 years and it was offered as an option on the XK150 (1957-1961) for while the XK120 (1948-1954) in 1948 had seemed streamlined modernity exemplified, the world had moved on and by 1957, although much improved and still stylish, the lines now seemed baroque rather than minimalist; the Leaper now fitted in well.  For the big Mark X saloon in 1961, paradoxically, a smaller Leaper was cast and this remained in use until the car (by then called 420G) was retired in 1970 so it was thus the last of the early Leapers, the XJ unadorned upon its debut in 1968 with the last of the legacy saloons (240, 340 (1967-1969 and both renamed and often de-contented versions of the Mark 2 (1959-1967)), S-Type (1963-1968) & 420 (1966-1968) produced in 1969.  The aftermarket though remained buoyant with many XJs and XJSs fitted with Leapers by owners who liked the look or dealers who thought they would.  It does seem they were fitted at the plant to many of the New Zealand-assembled XJs and the factory may have been in two minds about it: the hoods of all XJs (1968-1992) included on the underside skin- panel marks indicating where the holes should be drilled.  Not until the X300 XJ in 1994 would they again be factory-fitted to some models (in “pedestrian friendly” spring-loaded form) and this continued until 2005.

When in 1957 the Leaper appeared as an option on the XK150, Jaguar used the standard part fitted to the saloons but for the Mark X in 1961, a smaller version was cast, despite the car (stylistically something of a preview of the “fuselage” Chryslers of 1969) being the widest then produced in the UK (and it would remain so until 1992 when the company released the XJ220).  So, although the Leaper genuinely was smaller, the compression of relativities exaggerated the effect.  Jaguar took the opposite approach to Mercedes-Benz, the Germans creating a larger cartouche (the three-pointed star inscribed within a circle which sat atop the grill) for use on the big 600 Grosser (1963-1981).  What that did was maintain the relative dimensions familiar from the symbol’s use on smaller models.

Leaper on a US market 1999 Jaguar Vanden Plas (X308) which in the US market were fitted with the fluted grill used otherwise only on the Daimler variants.  The solid-timber picnic tables (a feature adored by the English middle class) were much admired.

The US market Vanden Plas models were the only Jaguars on which the Leaper was used in conjunction with the fluted grill fitted to the home market and RoW (rest of the world) Daimlers.  Because it was Mercedes-Benz and not Jaguar which after 1966 held the US rights to the Daimler brand, Daimlers since then sold in the US were badged as Jaguar Vanden Plas although they were otherwise identical to Daimlers including the fluted fittings.  The supercharged Daimler Vanden Plas was the most exclusive of the X308s and was noted for details such as the rear picnic tables being crafted from solid burl walnut timber rather than the veneer over plastic used on cheaper models.

1970 S2 Jaguar E-Type (top) from the "R2" run of 1000-odd (almost all of which were registered as 1971 models) with the Leaper badges on the flanks (left-side p/n BD35865 (left); right side p/n BD35866 (right)).  A Growler appeared in the front centre-bar (right).

The Series 2 E-Type (1968-1971) was marred by the clutter of bigger bumpers, protuberant headlight assemblies, badges and side-marker lights and so much did they detract from lovely, sleek lines of the Series 1 cars (1961-1967), bolting a luggage rack to the boot (trunk) lid probably seemed no longer the disfigurement it would once have been.  The disfigurement had begun with the transitional E-Types (the so-called 1.25 & 1.5 cars built in 1967) and indicate what would have been necessary to ensure post-1973 MGBs & MG Midgets conformed with the US headlight height stipulation.  It could have been done on the MGB but the shape of the Midget made the modification impossible (at least within aesthetic acceptability) but BL (British Leyland) took the cheaper route (always their preferred option) and raised the suspension height, compromising handling and lending the things a slight cartoonish quality but by then power had been so reduced by emission controls the view probably was handling prowess was no longer so important.  Remarkably, demand for both the by the antiquated MGB and Midget remained strong until sales finally ended in 1980.  The left-hand (left) and right-hand (right) fender badges, being directional, were different part numbers (BD35865 & BD35866 respectively) and those used on E-Types were silver on black whereas the variants used on the XJs were gold on black, some of which depicted the leaping feline at a slight slope, both matters of note for those wishing to restore cars to the challenging “factory original” standard.

1976 Jaguar XJC 4.2.

This XJC is one of many in the wild which, at some point, was fitted with a Leaper but it’s a shame whoever made the addition didn't at the same time remove the unfortunate vinyl roof.  Like the headlight covers sometimes added to the later (S1.25 & 1.5) S1 E-Types, removing an XJC's vinyl roof is one of the rare exceptions Jaguar's usually uncompromising originality police not only tolerate but encourage.  The Leaper badges on the flanks (behind the front wheel arch) were factory-fitted on the Series 1 (1968-1973) & Series 2 (1973-1979) XJs but whether on the XJ or E-Type were just disfiguring clutter and having them in silver & gold and with the feline sometimes at a different angle seems a minor but needless complication to the production process.

Still under the control of the doomed British Leyland, Jaguar lacked the resources fully to develop the XJC (1975-1998) and although it was displayed to much acclaim in 1973, not for another two seasons would it appear in showrooms, the programme starved of capital because greater priority was afforded to the XJ-S (1975-1996 and from 1991 officially “XJS”, a change most of the world informally had long adopted) which was thought a product with greater potential in the vital US market.  The XJC thus debuted with problems including (1) flawed sealing of the side windows which resulted in intrusive wind-noise, (2) a tendency of the doors to droop because, although longer and thus heavier than those of the four-door saloons, the same hinges were used and (3) the pillarless (ie a two-door hardtop) construction induced a slight flexing in the roof’s metal and while not a structural issue, because regulators had (quite sensibly) had lead removed from paint, the paint on the roof was prone to crazing.  The solutions (the development of exotic paint additives or re-designing the roof with heavier-gauge metal) would have been expensive and time-consuming so, in the British Leyland tradition, the Q&D (quick & dirty) approach was preferred and a vinyl roof was glued on but modern paints mean the ugly vinyl can now be removed so the roof’s lovely lines can be admired.  There are those who claim the “crazing paint” tale is just an urban myth and the awful stuff was glued on as a deliberate aesthetic choice because the look was then inexplicably popular (one of many lapses of good taste in the 1970s) but it's well-documented history.

Jaguar’s cancelled Growler (left) and the new (EV-friendly) Leaper.  According to the MBAs, the message the Leaper conveys is: “Always leaping forward, it is a representation of excellence and hallmark of the brand.

The companion bad to the Leaper was the “Growler” which featured the head of a Jaguar, mid-growl.  There were over the years many version of the Growler and it appeared variously on trunk-lids, grills, steering wheel bosses and such.  Because as a fitting it was never rendered in a way likely to cause injury to pedestrians, it might have been supposed it wouldn’t be vulnerable to cancellation but it transpired the Growler poses a significant moral hazard, presumably on the basis that while the somehow sensuously feminine Leaper is acceptable, the Growler embodies toxic masculinity.  Whether Jaguar’s MBAs discovered this from focus groups or divined it from their own moral superiority hasn’t be revealed but in 2024 the company announced the Growler would not re-appear when the new range was launched in 2025.  Given the public response to the DEI (diversity, equity & inclusion) themed preview of the company's EV (electric vehicle) re-brand, the presence or not of the Growler may not be of great significance but a new expression of the Leaper, (with something of a stylistic debt to the IBM logo), would be included so there’s that.

1985 Jaguar XJ-SC with after-market large Leaper.  Because of regulations, US the market XJ-S used quad circular headlights rather than the twin oval units otherwise fitted and while many don't like them, the "four eyes" look was closer to Jaguar's traditions.

Leapers have been fitted to some XJ-S and XJSs where they really don’t belong, the factory never installing one.  If it’s done, the least-worse approach is to use the small Leaper from the Mark X/420G and remove the Growler badge (if fitted) while the WCS (worst case scenario) is to leave Growler in place and add a large Leaper which really is too much clutter; with pre-modern Jaguars, less usually is more.  Still, for those who insist, reproductions of the classic 4¾ inch (120 mm) feline predator are available and those manufactured by German Jaguar tuner Jochen Arden comply with the EU’s rigorous safety regulations in that maximum pedestrian impact protection is afforded by the design integrating both lateral and horizontal rotation of the assembly.  The part is supplied as a kit which includes adapter plates to suit a number of otherwise leaperless jags and, being German-made, there is of course a “lifetime corrosion warranty”, the small print limited to (1) rusty Leapers purchased after November 2011, (2) not damaged and (3) validity restricted to the original purchaser and presentation of the original invoice.

1988 Jaguar XJ-S V12 Convertible by Hess & Eisenhardt (left) and 1989 Jaguar XJ-S V12 Convertible (right).  Note the bulkier soft-top used by the factory, necessitated by retention of the coupé's fuel tank.  The after-market, anodized plastic fittings on the wheel arches are, on an XJ-S, as undesirable as a Leaper.

When introduced in 1975, the XJ-S was available only as a coupé, the prevailing feeling in industry it was only a matter of time until US regulators outlawed convertibles.  For a number of reasons, the ban was never imposed and by the 1980s toes were again being dipped in the topless market, Jaguar in 1982 releasing the XJ-SC which featured a targa-like structure somewhere between that used on the Triumph Stag (1970-1977) and the various landaulets with “fold-back” roofs.  It was thus not a true “convertible” and sales were disappointing, demand limited further by the thing being purely a two-seater, the rear compartment re-configured as a generously-sized storage apace.  The dealer-feedback (notably from the US) however indicated there would be demand for a convertible XJ-S, something confirmed by US specialists Hess & Eisenhardt selling some 2000 of the conversions fabricated between 1986-1988.  Accordingly, in 1988 the factory released an XJ-S convertible and although also a two-seater, it proved a great success.  Interestingly, the factory’s design almost replicated the approach earlier taken by Jochem Arden with most of the coupe’s components retained.  This did necessitate the soft-top not folding especially low, unlike the Hess & Eisenhardt cars although to achieve that, modifications were made to the fuel tank and among some that proved controversial.

1968 Mercury Cougar GT-E 428 in Augusta Green Poly (left) and 1968 Mercury Cougar GT-E 427 in Grecian Gold (right).  Other than the Jaguaresque iconography, about the only thing European about the Cougar was the use of the French spelling of “litre”.  Ford in 1966-1967 also used a “7 Litre” badge, for a model which was fitted variously with the 427 & 428 cubic inch (7.0 litre) FE V8s.  The interchangeable badges were probably not a cost-saving measure but may have been to avoid the complaints Shelby American received as a consequence of fitting both the 427 and the less robust 428 to AC Shelby Cobras universally badged as “427”.

1968 Mercury Cougar GT-E 427 in Grecian Gold (left side badge).

Ford's Mercury division also had a stylized feline, introduced in 1967 when the Cougar debuted.  Unlike Jaguar's symbol, the cougar wasn't leaping but was caught more in mid-prowl although Mercury's marketing department would probably have liked people to have thought of it like that; the Cougar was that sort of car.  Although in colloquial use, cougars are often referred to as “big cats”, in zoological taxonomy, felinologists restrict the “big cat” classification to the genus Panthera (lions, tigers, leopards, snow leopards & jaguars) and one defining feature of the Panthera cats is their ability to roar, made possible by a specific adaptation in the larynx and hyoid bone.  Lacking the anatomical feature, like cheetahs, cougars are not able to roar.  Often known as the mountain lion, puma, or Puma concolor, despite their size, the cougar is more closely related to smaller cats so it’s properly a “large” cat rather than a “big cat”.
