Semaphore

Semaphore (pronounced sem-uh-fawr or sem-uh-fohr)

(1) A “line-of-sight” apparatus (mechanical, hand-held or activated and now even electronic) for conveying information by means of visual signals (typically flags or lights, the positions of which are changed as required).

(2) Any of various devices for signaling by changing the position of a light, flag or other identifiable indicator.  Historically, a common use of “semaphore” was as a noun adjunct (also called a noun modifier or attributive noun) including “semaphore flag”, “semaphore chart”, “semaphore operator et al.

(3) A codified system of signaling, especially a system by which a special flag is held in each hand and various positions of the arms denoting specific letters, numbers etc.  It remains part of Admiralty signals training.

(4) In biochemistry (as semaphoring), any of a class of proteins that assist growing axons to find an appropriate target and to form synapses.

(5) In biology (as semaphoront), an organism as seen in a specific time during its ontogeny or life cycle, as the object of identification or basis for systematics.

(6) In botany (as semaphore plant), a synonym for the telegraph plant (Codariocalyx motorius), a tropical Asian shrub, one of the few plants capable of rapid movement and so named because the jerking motions of the leaves recalled in observers the actions of the arms of Admiralty signallers and the name dates from the Raj.

(7) In programming, a bit, token, fragment of code, or some other mechanism which is used to restrict access to a shared function or device to a single process at a time, or to synchronize and coordinate events in different processes, the thread increments the semaphore to prevent other threads from entering the critical section at the same time.

(8) In figurative use (in human and animal behavior), certain non-verbal communications, used consciously and unconsciously, the concept often explored as a literary device.

(9) To signal (information) by means of semaphore

1814: From the French sémaphore, the construct being the Ancient Greek, σῆμα (sêma) (mark, sign, token) + the French -phore (from the Ancient Greek -φόρος (-phóros), the suffix indicating a bearer or carrier) and thus understood as “a bearer of signals”.  The Greek –phóros was from pherein (to carry), from the primitive Indo-European root bher- (to carry).  The verb was derived from the noun.  Semaphore is a noun & verb, semaphorist, semaphoront & semaphorin are nouns, semaphored is a verb, semaphoring is a verb & adjective, semaphoric & semaphorical are adjectives and semaphorically is an adverb; the noun plural is semaphores.  The noun semaphorism is non-standard but is used in behavioral linguistics to describe patterns of language used to convey meaning in a “coded” form which can be deconstructed for meaning only by sender and receiver.  The form semaphoreology seems not to exist but if anyone ever makes a discipline of the study semaphore (academic careers have been built from some improbable origins), presumably there will be semaphoreologists.

Semaphore flags are not always red and yellow, but the colors are close to a universal standard, especially in naval and international signalling.  There was no intrinsic meaning denoted by the use of red & yellow, the hues chosen for their contrast and visual clarity, something important in maritime environments or other outdoor locations when light could often be less than ideal although importantly, the contrast was sustained even in bright sunshine.  Because semaphore often was used for ship-to-to ship signalling, the colors had to be not only easily distinguishable at a distance but not be subject to “melting” or “blending”, a critical factor when used on moving vessels in often pitching conditions, the operator’s moving arms adding to the difficulties.  In naval and maritime semaphore systems, the ICS (International Code of Signals) standardized full-solid red and yellow for the flags but variants do exist (red, white, blue & black seem popular) and these can be created for specific conditions, for a particular cultural context or even as promotional items.

Early automobiles were sometimes fitted with mechanical semaphore signals to indicate a driver’s intention to change direction; these the British called “trafficators” (“flippers” in casual use) and they were still being fitted in the late 1950s, by which time they’d long been illuminated to glow a solid amber.  What the mechanical semaphores did was use the model of the extended human arm, used by riders or drivers in the horse-drawn age to signal their intentions to others and although obviously vulnerable to damage, the devices were at the time a good solution although the plastics used from the 1930s were prone to fading, diminishing the brightness.  When electronics advanced to the point where sequentially flashing turn indicators (“flashers”) cheaply could be mass-produced the age of the semaphore signal ended although they did for a while persist on trucks where they were attached to the exterior of the driver’s door and hand activated.

The A30 (1952-1956) was powered by an 803 cm³ (49 cubic inch) four cylinder engine while the Phantom III (1936-1939) was fitted with a 7338 cm³ (447 cubic inch) V12 (noted diarist Sir Henry “Chips” Channon (1897–1958) owned one) so the driving experience was very different but both used the same Lucas semaphore assembly.  Note the "BEWARE, TRAFFICATORS IN USE" notice in A30's rear window.  Because drivers are no longer attuned to look for the now archaic semaphores, some jurisdictions (while still allowing their operation), will permit road registration only if supplementary flashing indicators (now usually amber) are fitted.  In the 1960s many trafficator-equipped cars were modernized with flashers and it's now only collectors or restorers who prize the originality of the obsolete.

Although the grim realities of post-war economics meant standardization began to intrude, even in the 1950s Rolls-Royce made much of things being “bespoke” and while that was still true of some of the coach-work, what lay beneath the finely finished surface was often from the industry parts-bin and the semaphore turn signals the company fitted to the Silver Wraith (1946-1958) and Silver Dawn (1949-1955) was Lucas part number SF80, exactly the same component used by the humble Austin A30 and Morris Minor (1948-1971) where the functionality was identical.  Presumably, were one to buy the part from Rolls-Royce one would have been charged more (perhaps it was wrapped in more elaborate packaging) and that’s a well-understood industry phenomenon.  The internet has made it easier to trace such commonalities but in the 1980s there was a most useful publication which listed shared part-numbers which differed only in the prices charged, a switch for a Lamborghini which might retail for hundreds available from the Fiat parts counter (a busy place folklore suggests) for $12 while those aghast at the price quoted for a small linkage in a Triumph’s Stag’s induction system were pleased the same thing could be bought from a Ford dealer for a fraction of the cost.  Rolls-Royce fitted their last trafficator in 1958 and when Austin updated the A30 as the A35 (1956-1968) flashers were standard equipment, metal covering the apertures where once the semaphores had protruded while internally there was a panel concealing what had once been an access point for servicing.  The Morris Minor, the last of which wasn’t (in CKD (completely knocked down) form) assembled in New Zealand until 1974(!) switched from trafficators to flashers in 1961, the exterior and interior gaps concealed al la the A35.

The Latin sēmaphorum (the alternative form was sēmaphoru) is thought to be a calque of the Italian semaforo (traffic light), again borrowed from the French sémaphore in the literal sense of “signaling system”.  The modern Italian for “traffic light” is semaforo although (usually for humorous effect) sēmaphorum is sometimes used as Contemporary Latin.  Traffic lights have for over a century regulated the flow of vehicles in urban areas but the first semaphore signal predated motorized transport, installed in London in 1868.  It was introduced not because it would perform the task better than the policemen then allocated but because it was cheaper and was an example of the by then common phenomenon of machines displacing human labor.  The early mechanical devices were pre-programmed and thus didn’t respond to the dynamics of the environment being controlled and that applied also to the early versions of the now familiar red-amber-green “traffic lights” which began to proliferate in the 1920s but by the 1950s there were sometime sensors (weight-sensitive points in the road) which could “trigger” a green light if the pre-set timing was creating a needless delay.  Even before the emergence of AI (artificial intelligence) in the modern sense of the term, implementations of AI had been refining the way traffic light systems regulated vehicular flow and in major cities (China apparently the most advanced), cameras, sensors, face and number plate recognition all interact to make traffic lights control the flow with an efficiency no human(s) could match.

ASMR semaphore porn: 1955 Austin A30.  ASMR (Autonomous Sensory Meridian Response) describes the physical & psychological pleasure derived from specific stimuli (usually a sound).  For some, this can be the sight & sound of South Korean girls on TikTok eating noodles while for those fond of machines it can come from hearing semaphore turn-signals being raised and lowered.

Whether it was the early semaphore signals or the soon to be ubiquitous illumined red-amber-green lights, what the system relied on was compliance; inherently, lacking physical agency, a piece of colored glass can’t stop a car but that almost always is the effect of a “red light”.  In behaviorism, this was described as discriminative stimulus (SD) in that the red light culturally is understood as a universal cue signalling a punishment might follow any transgression (ie “running the red light”), thus the incentive to obey the signal and avoid negative consequences (crashing or being fined).  What SD does is control behavior through learned association.  The use of red comes from semiotics and the color is culturally assigned to “stop” as green is to “go”, these allocated by virtue of historical associations which long pre-date the technology in the same way semiotics are used (as red & blue) to denote “hot” & “cold” water when taps are labelled, meaning for travellers no knowledge of a local language is needed to work out which is which.  In the jargon, the red light is a “signifier” and the “signified” is stop.

Sir William Morris (1877-1963; later Lord Nuffield) held a number of troubling and even at the time unfashionable views and he’d been sceptical about producing the Morris Minor, describing the prototype as looking “like a poached egg”; in that he was right but the Minor proved a highly profitable success.  In the 1930s however, he did have the imaginative idea of adapting the by then familiar traffic light (in miniature form) to the automobile itself.  The concept was sound, Sir William’s proposed placement even anticipating the “eye level brake lights” of the 1980s and the inclusion of green in the code was interesting but the “mini traffic light” wasn’t taken up and lesson which should have been learned is that in the absence of legislation compelling change, the industry always will be most reluctant to invest and not until the 1960s would such mandates (for better and worse) begin to be imposed.

In idiomatic use, semaphore’s deployment tends to be metaphorical or humorous, the former used as a literary device, borrowed from behavioral psychology.  “To semaphore” can mean “wildly or exaggeratedly gesture” but can also convey the idea of a communication effected without explicitly stating something and that can either be as a form of “unspoken code” understood only between the interlocutors or something unconscious (often called body-language).  “Semaphoring a message” can thus be either a form of secret communication or something inferred from non-verbal clues.  Authors and poets are sometimes tempted to use “semaphore” metaphorically to describe emotional cues, especially across physical or emotional distance and one can imagine the dubious attraction for some of having “her sensuous lips silently semaphoring desire” or “her hungry eyes semaphored the truth”.  Among critics, the notion of “semaphoring” as one of the motifs of modernist literature was identified and TS Eliot’s (1888–1965) style in The Waste Land (1922) included coded fragments, often as disconnected voices and symbols, called by some an “emotional semaphore” while Samuel Beckett (1906-1989 and another Nobel laureate) was noted for having his characters exchange their feelings with repetitive gestures, signals and critically, silences, described variously as “gestural semaphore” or the “semaphoring of despair”.

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.

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.

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”.

Catwalk

Catwalk (pronounced kat-wawk)

(1) A narrow walkway, especially one high above the surrounding area, used to provide access or allow workers to stand or move, as over the stage in a theater, outside the roadway of a bridge, along the top of a railroad car etc; any similar elevated walkway.

(2) By extension, a narrow ramp extending from the stage into the audience in a theatre, nightclub etc, associated especially with those used by models during fashion shows (although the gender-neutral “runway” is now sometimes used in preference to “catwalk”).

(3) In nautical architecture, an elevated enclosed passage providing access fore and aft from the bridge of a merchant vessel.

(4) By extension, as "the catwalk", industry slang for the business of making clothes for fashion shows.

1874: The construct was cat + walk.  The use of catwalk to describe a long, narrow footway was a reference initially to those especially of such narrowness of passage that one had to cross as a cat walks.  It applied originally to ships and then theatrical back-stages, the first known use with a fashion show runway dating from 1942.  In architecture on land and at sea, the catwalk soon lost its exclusive association only with the narrow and came instead to be defined by function, used to describe any walkway between two points.  The noun plural is catwalks.  For both nautical and architectural purposes, the English catwalk was borrowed by many languages including Norwegian (Bokmål & Nynorsk) and Dutch and it’s used almost universally in fashion shows.  Some languages such as the Ottoman Turkish قات‎ use the spelling kat and some formed the plural as catz.

Cat (any member of the suborder (sometimes superfamily) Feliformia or Feloidea): feliform (cat-like) carnivoran & feloid or any member of the subfamily Felinae, genera Puma, Acinonyx, Lynx, Leopardus, and Felis or any member of the subfamily Pantherinae, genera Panthera, Uncia and Neofelise and (in historic use, any member of the extinct subfamily Machairodontinae, genera Smilodon, Homotherium, Miomachairodus etc, most famously the Smilodontini, Machairodontini (Homotherini), Metailurini, "sabre-toothed cat" (often incorrectly referred to as the sabre-toothed tiger) but now most associated with the domesticated species (Felis catus) of felines, commonly and apparently since the eight century kept as a house pet)) was from the Middle English cat & catte, from the Old English catt (male cat) & catte (female cat), from the Proto-West Germanic kattu, from the Proto-Germanic kattuz, from the Latin cattus.

Cat has most productively been applied in English to describe a wide variety of objects and states of the human condition including (1) a spiteful or angry woman (from the early thirteenth century but now almost wholly supplanted by “bitch” (often with some clichéd or imaginative modifier)), (2) An aficionado or player of jazz, (3) certain male persons (a use associated mostly with hippies or sub-set of African-American culture), (4) historic (early fifteenth century) slang for a prostitute, (5) in admiralty use, strong tackle used to hoist an anchor to the cathead of a ship, (6) in admiralty use, a truncated form of cat-o'-nine-tails (a multi-lash (not all were actually nine-tailed)) whip used by the Royal Navy et al to enforce on-board discipline), (7) in admiralty use, a sturdy merchant sailing vessel (long archaic although the use endures to describe the rather smaller "catboat", (8) as “cat & dog (cat being the trap), a archaic alternative name for the game "trap and ball", (9) the pointed piece of wood that is struck in the game of tipcat, (1) In the African-American vernacular, vulgar slang or the vagina, a vulva; the female external genitalia, (11) a double tripod (for holding a plate etc) with six feet, of which three rest on the ground, in whatever position it is placed, (12) a wheeled shelter, used in the Middle Ages as a siege weapon to allow assailants to approach enemy defenses, (13) in admiralty slang, to vomit, (14) in admiralty slang to o hoist (the anchor) by its ring so that it hangs at the cathead, (15) in computing, a program and command in the Unix operating system that reads one or more files and directs their content to the standard output (16) in the slang of computing, to dump large amounts of data on an unprepared target usually with no intention of browsing it carefully (which may have been a sardonic allusion of “to catalogue or a shortened form of catastrophic although both origins are unverified, a street name of the drug methcathinone, (17) in ballistics and for related accelerative uses, a shortened form of catapult, (18) for purposes of digital and other exercises in classification, a shortening of category, (19) an abbreviation of many words starting with “cat”) (catalytic converter, caterpillar (including as “CAT” by the manufacturer Caterpillar, maker of a variety of earth-moving and related machines)) catfish, etc, (20) any (non military-combat) caterpillar drive vehicle (a ground vehicle which uses caterpillar tracks), especially tractors, trucks, minibuses, and snow groomers.

Walk was from the Middle English walken (to move, roll, turn, revolve, toss), from the Old English wealcan (to move round, revolve, roll, turn, toss) & ġewealcan (to go, traverse) and the Middle English walkien (to roll, stamp, walk, wallow), from the Old English wealcian (to curl, roll up), all from the Proto-Germanic walkaną & walkōną (to twist, turn, roll about, full), from the primitive Indo-European walg- (to twist, turn, move).  It was cognate with the Scots walk (to walk), the Saterland Frisian walkje (to full; drum; flex; mill), the West Frisian swalkje (to wander, roam), the Dutch walken (to full, work hair or felt), the Dutch zwalken (to wander about), the German walken (to lex, full, mill, drum), the Danish valke & waulk), the Latin valgus (bandy-legged, bow-legged) and the Sanskrit वल्गति (valgati) (amble, bound, leap, dance).  It was related to vagrant and whelk and a doublet of waulk.

Walk has contributed to many idiomatic forms including (1) in colloquial legal jargon, “to walk” (to win (or avoid) a criminal court case, particularly when actually guilty, (2) as a colloquial, euphemistic, “for an object to go missing or be stolen, (3) in cricket (of the batsman), to walk off the field, as if given out, after the fielding side appeals and before the umpire has ruled; done as a matter of sportsmanship when the batsman believes he is out or when the dismissal is so blatantly obvious that the umpire’s decision is inevitable, (4) in baseball, to allow a batter to reach first base by pitching four balls (ie non-strikes), (5) to move something by shifting between two positions, as if it were walking, (6) (also as “to full”, to beat cloth to give it the consistency of felt, (6) in the slang of computer programming, to debug a routine by “walking the heap”, (7) in aviation, to operate the left and right throttles of an aircraft in alternation, (8) in employment, to leave, to resign, (9) in the now outlawed “sports” of dog & cock-fighting, to put, keep, or train (a puppy or bird) in a walk, or training area, (10) in the hospitality trade, to move a guest to another hotel if their confirmed reservation is not available at the time they arrive to check-in (also as to bump), (11) in the hospitality trade, as “walk-in”, a customer who “walks-in from the street” to book a room or table without a prior reservation, (12) in graph theory, a sequence of alternating vertices and edges, where each edge's endpoints are the preceding and following vertices in the sequence, (13) In coffee, coconut, and other plantations, the space between the rows of plants (from the Caribbean and most associated with  Belize, Guyana & Jamaica, (14) in orchids, an area planted with fruit-bearing trees, (15) in colloquial use, as “a walk in the park” or “a cakewalk”, something very easily accomplished (same as “a milk-run”) and (16) in the (now rare) slang of the UK finance industry, a cheque drawn on a bank that was not a member of the LCCS (London Cheque (check in the US) Clearance System), the sort-code of which was allocated on a one-off basis; they had to be "walked" (ie hand-delivered by messengers).

Especially since the ratio of fabric to flesh on red carpets shrunk during the last two decades, critics and the public alike have become jaded, shock and surprise harder to achieve on the catwalk.  However, at Paris Fashion Week 2025, what had become elusive with fabric and flesh and was achieved with latex, a male model appearing in a gender-bending top during the presentation of Dutch designer Duran Lantink's (b 1998) fall 2025 Duranimal collection.  What turned out to be the most publicized item in the Palais de Tokyo Room wasn’t the collection of pieces featuring bold animal prints with striking silhouettes, but one never to be in any high street catalogue, a flesh-colored torso with a pair of realistic, jiggling, prosthetic breasts worn by male model Chandler Frye.

Tit for tat: Mica Argañaraz strutting in T-shirt.

What the male mode wore was, in design terms, a crop top, albeit one with untypical choices in material and construction, and the companion piece was worn by model Mica Argañaraz: a T-shirt also in skin-tone latex, molded in the form of an idealized male torso, something like those the sculptors of Antiquity once carved in marble.  Both were on display on a catwalk which snaked around a maze of cubicles filled with headset-wearing workers shuffling and stapling papers, something which may have had some thematic connection which what was on show although no explanation was provided.  While the T-shirt seems to have provoked few comments, there were criticisms of the latex boobs, usually in some way an objection to the objectification of the female body (something generally thought a battle long lost) while others denied this could possibly thought “fashion” which was about as pointless an observation as any of those by the many who over the years have dismissed porcelain urinals, drip paintings and such as “not art”.  When asked about the use of a woman’s body as a “costume” (nobody asked about the make torso), Mr Lantink replied it was “…about cosplay, it’s playing with bad taste, it’s about form. Every season, we’re trying to sort of surprise ourselves with how can we change an original piece into something that we find interesting”, adding: “And we’re gonna do whatever the fuck we want because we’re free.”

How to walk like catwalk model

Traci Halvorson of Halvorson Model Management (HMM) in San Jose, California, has written a useful guide for those wishing to learn the technique of walking like a catwalk (increasingly now called the gender-neutral “runway”) model.  Although walking on a wide, stable flat surface, in a straight line with few other instructions except “don’t fall over”, doesn’t sound difficult, the art is actually a tightly defined set of parameters which not all can master.  Some models who excel at static shots and are well-known from their photographic work can’t be used on a catwalk because their gait, while within the normal human range, simply isn’t a “catwalk walk”.  It’s thus a construct, of clothes, shoes, style and even expression and catwalk models need to be adaptable, able to achieve essentially the same thing whether in 6-inch (150 mm) high stilettos or slippery-soled ballet flats; it’s harder than it sounds and as all models admit, nothing improves one’s technique like practice.

(1) The facial expression.  It sounds a strange place to start but it’s not because if the facial expression is unchanging it means it’s easier to focus on everything else, the rational being that humans use their range of facial expression to convey emotion and attitude but this all has to be neutralized to permit the photographers (paradoxically the audience is less relevant) to capture what are defined “catwalk” shots.  Set the chin to point slightly down though don’t hang the head; the angle should be almost imperceptible and it recommended to imagine an invisible string attached to the top of the head holding the chin in its set position.

(2) Do not smile.  Catwalk models do not smile because it draws attention away from the product although this does not mean looking miserable or unhappy; instead look “serious” and this usually is done by perfecting what is described as a “neutral” expression, one which would defy an observer being able to tell whether the wearer is happy or sad.  To achieve this, the single most important aspect is to keep the mouth closed in a natural position, something like what is recommended for a passport photograph and ask others to judge the look but as a note of caution, there will be failures because some girls just look sort of happy no matter what.  In most of life, this will be of advantage so a career other than the catwalk will beckon.

(3) On the catwalk, keep the eyes focused straight ahead.  This not only makes walking easier but also self-imposes a discipline which will help maintain the static facial expression.  Because the eyes are focused straight-ahead, it will stop the head moving and the look will be the desired one of alertness and purposefulness.  Some models recommend imagining a object moving in front of them and focus on that and in the situations where there’s a procession on the catwalk, it’s possible usually to fixate on some unmoving point on the model ahead.

(5) Don’t fall over.  It’s an obvious point but it does happen and usually, shoes are responsible, either because the nature of the construction has so altered the model’s centre of gravity or there's  contact between footwear and some flowing piece of fabric, either one’s own or one in the wake of the model ahead.  There is no better training to avoid “catwalk stacks” than to practice in a wide variety of shoe types.

(5) If possible, arrange a replica catwalk on which to practice, it need only to be a few paces long and arranged so the walk is towards a full-length mirror.  For side views, film using a carefully positioned camera and compare the result with footage of actual catwalk models at work.  If possible, work in pairs or a group because you’ll hone each other’s techniques but remember this is serious business and criticism will need to be frank; feelings may need to be hurt on the walk to the catwalk.

(6) Stand up straight, imagining the invisible string holding the head in place being also attached to the spine.  Keep the shoulders back but not unnaturally so, posture needs to be good but not stiff or exaggerated and a good posture can to some extent compensate for a lack of height.  Again, this needs to be practiced in front of a mirror and practice will improve the technique, the object being to stand straight while looking relaxed and comfortable.

(7) Perfecting the actual catwalk walk will take some time because, although it looks entirely natural when done by models, it’s not actually the “natural” way most people walk.  To train, begin purely mechanistically, placing one foot in front of the other and walking with (comfortably) long strides, the best trick being to mark a line on the floor with chalk and imagine walking on a rope, keeping one foot in front of the other, allowing the hips slightly to move from side to side; the classic model look.  With sufficient practice, what designers call the model’s “strut” will evolve and in conjunction with the other techniques, there’ll be a projection of assuredness and confidence.

(8) However, the hips need symmetrically and slightly to move, not swing.  Catwalk models are hired as platforms for clothes within a narrow dimensional range and this includes not only the cut of the fabric but also the extent it is required to move as the body moves and motion must not be exaggerated.  When practicing this, again it’s preferable to work in pairs or groups.

How it's done.  Catwalk models need to look good coming or going.

(9) Limit the movement of the arms when walking.  Let the arms hang at the sides with the hands relaxed, the swing of the limbs sufficient only to ensure the look is not unnaturally stylized and certainly nothing like that of most people on the street.  Many report when first practicing that there’s a tendency for the hands to clench into fists and that’s because of the discipline being imposed on other body parts but from the start, ensure the hands are relaxed, loosely cupped and with a small (natural) gap (something like ¼ inch (5-6 mm) between the fingers.  Allow the arms slightly to bend and they’ll sway (just a little) with the body.

(10) Practice specifically for the occasion.  Just as even the best tennis players have to practice on grass if they’ve just come off playing on clay or hard-courts, at least an hour before an actual catwalk session should be spent practicing in the same style of shoes as will be worn for the session(s).  This applies even if wearing something less challenging like flats because the change in weight distribution and the resultant centre of gravity is profound if the last few days have been spent in 6 inch (150 mm) heels.     

(11) Practice with different types of music because the catwalk walk really is an exercise in rhythm and if one can find a piece which really suits and makes the walk easier to perfect, if it’s possible to imagine that while on the catwalk, that’s good although sometimes there’s music at the shows and not all can focus on what’s in the head while excluding what’s coming through the speakers.

Traci Halvorson's instructions were of course aimed at neophytes wishing to learn the basic technique but among established models there are variations and the odd stake of the individualistic, the most eye-catching of which is the "fierce strut", a usually fast-paced and aggressive march down the catwalk while still using the classic one-foot-in-front-of-the-other motif which so defines the industry.  It's thus not quite Nazi-style goose-stepping or even the hybrid step used most enthusiastically by the female soldiers in the DPRK (North Korean) military but it's clearly strutting with intent.
