Corona

Corona (pronounced kuh-roh-nuh)

(1) A white or colored circle or set of concentric circles of light seen around a luminous body.

(2) In meteorology, such a circle or set of circles having a small radius and ranging in color from blue inside to red outside, attributable to the diffraction caused by thin clouds, mist, or sometimes dust (distinguished from halo).

(3) In solar astronomy, a faintly luminous envelope outside of the sun's chromosphere, the inner part consisting of highly ionized elements; also called aureola & aureole.

(4) A long, straight, un-tapered cigar, rounded at the closed end.

(5) In botany, a crown-like appendage, especially one on the inner side of a corolla, as in the narcissus.

(6) In anatomy, the upper portion or crown of a part, as of the head.

(7) In architecture, the projecting, slab-like member of a classical cornice supported by the bed molding or by modillions, dentils, etc., and supporting the cymatium.

(8) The tonsure of a monk or other cleric.

(9) In ecclesiastical dress, a gold-colored stripe around the lower edge of a clerical headdress, as of a miter.

(10) A chandelier of wrought metal, having the form of one or more concentric hoops.

(11) In zoology, the head or upper surface of an animal, such as the body of an echinoid or the disc and arms of a crinoid.

(12) As Coronaviruses, a group of viruses which infect mammals and birds.  In humans, they cause usually mild (including 229E, the common cold) respiratory infections but forms such as SARS, MERS the famous COVID-19 can be lethal.

1555–1565: From the Latin corōna (garland, crown) from the Ancient Greek κορώνη (korṓnē or korōnis (crown, any curved object)), akin to korōnís (wreath; curved, beaked) & kórax (crow; raven); related was the Latin curvus (curved).  A doublet of crown, the plural forms are coronas & coronae.

COVID-19 and Coca-Cola

COVID-19 (an abbreviation of coronavirus disease 2019) was the name of the disease caused by SARS-CoV-2.  The name was adopted in February 2020, chosen by the World Health Organization (WHO) in partnership with the Committee on Taxonomy of Viruses; until then, variously it had been called 2019-nCoV, Novel coronavirus or Wuhan coronavirus.  SARS-CoV-2 is related to MERS-CoV (which causes Middle East respiratory syndrome (MERS)) and SARS-CoV (which causes severe acute respiratory syndrome (SARS)).

The class to which these viruses belong is called corona because, when viewed under an electron microscope, there’s a resemblance to the crown-like corona (the halo or ring of fire) around the Sun, seem when viewed through an appropriate telescope or other device.  The corona around the sun has long been known but viruses have been seen only since the development of the electron microscope because human viruses are very small, typically 100 nanometers (1 metre = 1,000 mm = 1,000,000 micrometres = 1,000,000,000 nanometres).  In the evolutionary timeline of life on earth, it's believed bacteria emerged quite some time before viruses.  Bacteria appear to have been one of the earliest forms of life and, because no evidence of life has yet been detected anywhere else in the universe, they're perhaps among the oldest anywhere.  Single-celled organisms with a relatively simple structure and capable of independent reproduction, bacteria are thought to have appeared some 3.5 to 3.8 billion years ago (the Earth dating back 4.5 billion) and the evidence suggests the viruses emerged 2-3 billions years ago.  Unlike bacteria, viruses are not considered living organisms in the traditional sense because they cannot carry out metabolic processes or reproduce on their own; instead, they are genetic material (DNA or RNA) enclosed in a protein coat.

As far as is known, all life forms now extant (and all extinct forms known) are descended ultimately from the one initial instance; life started once which means humans are related to cats, dogs, trees & bananas as well as to bacteria & viruses.  That makes people, bacteria and just about everything else vulnerable to infection by one virus or another, the consequences ranging from nothing to death but the behavior can also be used to advantage and a certain class of virus, the bacteriophage, after a long period of neglect during the antibiotic era, is attracting new interest.

Some viruses can be helpful: A depiction of bacteriophages phaging.

Not all viruses are bad like SARS-CoV-2.  A bacteriophage, known almost always as a phage, is a virus which infects and replicates within bacteria.  Phages are composites of proteins that surround a DNA or RNA genome and may encode any number of genes from a handful to many hundreds.  Phages replicate within the bacterium following the injection of their genome into the target cytoplasm.  Phages exist naturally in the environment and are among the most common and diverse entities on earth.  Serious research began in several parts of Europe during the late nineteenth century and have been used for almost a century as anti-bacterial agents the former USSR and Central Europe.  In the West, phage therapy (using specific viruses to fight difficult bacterial infections) has been of interest for some time, attention heightened as the problem of antibiotic-resistant bacteria (superbugs in the popular imagination) began to grow in severity (the US Centers for Disease Control and Prevention (CDC) attributes one death every 15 minutes in the US to superbugs).  Since the discovery of penicillin, antibiotics have been used as a reliable cure for those suffering from once lethal bacterial infections but, over decades, a handful (compared with the trillions and trillions killed) of bacteria have proved resistant to antibiotics and as these survivors multiply, new infections emerge.  Historically this had prompted the development of revised or new antibiotics but the biological arms race has reached the point where some infections caused by called antibiotic resistant bacteria cannot be treated and for many other serious infections, the number of potent “last resort” antibiotics is dwindling.

Hence the interest in phages, a type of “friendly virus” which can be weaponized to fight even the most virulent and persistent bacterial infections.  Phages work as well as they do because viruses like the tiresome SARS-Cov-2 that makes humans sick, phages can infect only bacteria and are selective about which they target, a vital aspect of their role in medicine because human survival depends on the billions of bacteria in our bodies.  These phages are far from rare, existing in the natural environment almost everywhere on the planet and scientists conducting research find dirty waterways or damp, aerated, warm, decaying soil (both areas where high bacterial growth might be expected) are good places to collect samples.  The advantages phages offer are well known but there are also drawbacks and indeed some of the features of phages manifest as both.  For example, the great specificity of phages helpful in that they can be administered safely with the knowledge that no other organisms will be harmed but this can be a practical disadvantage in clinical medicine when it’s not known exactly which bacteria need to be targeted, which is why broad-spectrum antibiotics proved so effective at scale.  Being wholly natural, the shelf-life of phages is highly variable and there’s little experience in their administration beyond some communities in Eastern Europe where they’ve been part of medical practice for over a century.  Additionally, bacteria can develop resistance even to phages and one practical impediment to deployment not well recognized until recent years is that compared to chemical molecules, phages are quite big and there are sites in the human body which will be inaccessible.

Electron micrograph of a Coronaviruses in colorized and in grey-scale.

The images captured from electron microscopes are always in black-and-white but are often artificially colored in the post-production process for better visualization and to assist with analysis.  Because of the resolution limit of the optical microscope, even at the highest magnification, viruses couldn’t be seen because their size meant they lay beyond the spectrum of visible light, the range of resolution being limited by the wavelength of the visible light that illuminates the specimen.  It was the resolution of the electron microscope, developed in the early 1930s, and able to offer an illumination with a wavelength much smaller than visible light which first made viruses visible.  An electron has the properties both of a particle and a wave so an electron’s wavelength is determined by its energy (or speed).  If an electron is accelerated to a speed of a million meters per second (circa 2.2 million mph (3.5 million km/h)) the physical wavelength is around one-tenth of a nanometer or about the size of an atom.  This permits an electron microscope to probe the structure of atoms in a crystal and thus see viruses.

Lindsay Lohan taking a 330ml lunch.

In February 2021, at a time when the official number of people with COVID-19 was around 107 million, mathematicians calculated all the COVID-19 causing SARS-COV-2 virus then circulating the planet easily would fit in a single (330ml) Coca-Cola can.  Using a model based on the viral load per currently infected victim (which varies during the duration of the infection), it was estimated there were at the time around two-hundred quadrillion (200 million billion or 2x10¹⁷). SARS-CoV-2 virus particles in the world.  Using that number, knowing the size of the virus, it was possible to calculate the total volume and even after accounting for the distinctive projecting spike proteins meaning the spherical particles will leave gaps when stacked together, the total is still less than the internal volume of the 330 millilitre can.

Two-hundred quadrillion is a really big number, there are said to be about that many grains of sand on the planet, but Sars-CoV-2 particles are really small, around a hundred nanometres (one nanometre is a billionth of a meter) so the radius of Sars-CoV-2 is roughly a thousand times thinner than a human hair.  The mathematicians multiplied the numbers, worked out the wastage of space caused by the troublesome spikes accounted for about a quarter of the total volume and concluded that in February 2021, the volume of SARS-CoV-2 in the world was 160 millilitres.  By mid-2021, cases had almost doubled so by then, either the can would be full or, given the margin of error associated with such calculations, a second can might be required.  The caveat to all this is that the math is based on the official number of infected people and nobody knows what the real is although all agree it will be higher but by what factor is guesswork, reliable data just not available to build a model.  Guesses have been proffered ranged from double to twenty times higher.  Depending on which of those is closest, a six-pack or a carton of cans might be filled.

The Toyota (Corona) 1600GT

1958 Toyota Corona "Van".

It was the Toyota Corona (1957-2001) which not only established the company in the vital US market but lent respectability to the very idea of the “Japanese car”, that term in the early 1960s not the by-word for quality and reliability it would in subsequent decades become.  Noting the success of the small (by US standards) Volkswagen Beetle and other imports, the company shipped a small number of Coronas to the US in the late 1950s but they were unsuitable for the environment (as indeed were a number of the diminutive European models which lacked the ruggedness of the VW) and interest was minimal, the Corona withdrawn from sale in 1960 although unsold models lingered on the lots for another year.

1966 "shovel-nose" Toyota Corona.

It was the third generation Corona, launched in September 1964 in an array of body styles, which was the Toyota passenger car to achieve international success, including in the US.  It was a thoroughly conventional design (ie mechanically a scaled down US sedan) with a body which was modern, inoffensive and practical although some thought the reverse-slanted nose strange.  It came to be nick-named the “shovel-nose” and proved ahead of its time, adopted in 1972 by Lancia for the Beta and in 1976 it appeared on Ford’s Escort RS2000 before variations of the shape eventually became the default for manufacturers seeking to eke out as much aerodynamic efficiency as possible.

The "shovel-nose" caught on: 1972 Lancia Beta (left) & 1976 Ford Escort RS2000 (right).  

The export range appeared in volume but the most desirable models were reserved for the JDM (Japanese domestic market), a long-standing, industry-wide practice which has had the effect of creating a minor export business for those who can satisfy the demand in markets like Australia, New Zealand & North America for the high-performance versions which have something of a cult-following.  The 1967 1600GT (or GT-5 for those with the optional five-speed gearbox) coupé (for this JDM “halo” model the Corona badge wasn’t used) was modest compared with some of the wild machinery which would appear in subsequent decades but by the standards of its time, there was some genuine sophistication.  The body was the standard two-door hardtop but the centrepiece was a double overhead camshaft (DOHC) cylinder head atop the 1600 cm³ four cylinder engine, the head designed by Yamaha which had also developed the one used on the straight-six in the exotic Toyota 2000 GT sports car made famous by the appearance of a custom built roadster version in the James Bond film You Only Live Twice (1967).

1967 Toyota 2000GT roadster.  Two 2000GT coupés were converted into roadsters for You Only Live Twice (one used for filming, the other a "back-up"), the work undertaken by Toyota’s special Toyopet Service Centre in Tsunashima.  The wire wheels were exclusive to the roadsters (15×5 inch magnesium wheels were used on the coupés) and the pair were very much movie props, neither vehicle fitted with side windows or a soft-top.  The "back-up car" is now on display in the Toyota Automobile Museum.

Known internally as the 9R, the 1600GT engine took a traditionally English approach to increasing power: twin carburetors, big valves and a high-compression ratio, the combination yielding a then impressive 110 horsepower at 6200rpm, the latter number something to note given the crankshaft was supported by only three main bearings.  Still, being a Toyota engine, reliability was solid and no history of bottom-end failure emerged; whether the unusual firing order (1243) had anything to do with this seems not to be discussed anywhere.  To cope with the new-found power, the Corona’s suspension was strengthened with re-calibrated springs and dampers along with two torque rods to locate the back axle.  That improved things but the Japanese manufacturers, although matching the Europeans in power, still had some way to go in achieving their dynamics; the 1600 GT was no cut-price Alfa Romeo.  It was though very well equipped, another lesson Toyota and other Japanese factories would (painfully) teach the West.  Always a low volume model, production of 1600 GTs totalled 2222, the last built late in 1968.

1974 Toyota Corona advertising.

The 1600GT's cult following notwithstanding, it really wasn't representative of the Coronas which went around the world and for decades provided owners and fleets with reliable, if uninspiring transport (very much the Camry of their time).  That made them memorable for many who may have enjoyed the charms of British, French or Italian machinery but found the quirks, oil-leaks, fragility or apparently insoluble issues electrical issues (often described as "gremlins") made ownership tiresome.  Toyota were aware of the advantage their approach (which put a premium on basic engineering and quality control over the finer points of handling and high-speed braking) and their advertising for the Corona in the 1970s said explicitly: "When your heart says Europe but your head says Japan".  People increasingly followed their heads and by 1989 Toyota released the Lexus, proving they were as good at building a Mercedes-Benz as they were at building Toyotas.  It took many attempts for Mercedes-Benz to become (almost) as good at building Toyotas.

Roadster

Roadster (pronounced rohd-ster)

(1) An early automobile having an open body, a single seat for two or three persons, and a large trunk or a rumble seat.

(2) A horse for riding or driving on the road (archaic).

(3) A two-seater, convertible sports car.

(4) A sea-going vessel riding at anchor in a road or bay.

(5) In coastal navigation, a clumsy vessel that works its way from one anchorage to another by means of the tides.

(6) A bicycle, or tricycle, adapted for common roads, rather than for the racing track, usually of classic style and steel-framed construction (archaic).

(7) Slang for one who drives much or one who lives along the road (UK (8) archaic).

(8) Slang for a hunter who keeps to the roads instead of following the hounds across country (archaic).

(9) The pre-modern class of racing car most associated with the classic era of the Indianapolis 500 (1952-1964).

1735–1745: A compound word, road + -ster.  Road was from the Middle English rode & rade (ride, journey) from the Old English rād (riding, hostile incursion) from the Proto-Germanic raidō (a ride), from the primitive Indo-European reydh (to ride). It was cognate with raid, a doublet acquired from the Scots, and the West Frisian reed (paved trail/road, driveway).  The –ster suffix is applied to someone (or something) associated with an act or characteristic, or does something specified.  It’s from the Middle English –ster & -estere from the Old English -estre (-ster, the feminine agent suffix), from the Proto-Germanic –istrijǭ &, -astrijǭ from the primitive Indo-European -is-ter- (suffix).  It was cognate with the Old High German -astria, the Middle Low German –ester and the Dutch -ster.  Roadster is a noun; the noun plural is roadsters.

Roadsters, gullwings and courtesans

1920 Stutz Bearcat, the classic American roadster of the early inter-war years.  Such was its allure, it was (apocryphally) claimed that should anyone die at the wheel of a Stutz Bearcat, they were granted an obituary in the New York Times (NYT).

In the United States of the mid-nineteenth century, a roadster was a horse suitable for travelling and by the early 1900s, the definition had expanded to include bicycles and tricycles.  In 1916, the US Society of Automobile Engineers (SAE) defined a roadster as "an open car seating two or three”, a meaning which endures to this day.  Despite the origins, use was patchy in the US with the word applied to vehicles as diverse as the front-engined USAC (Indy) racing cars of the 1950s, a variety of 1930s convertibles and the custom post-war creations otherwise known as hot-rods.

Two of the 1963 Kurtis Kraft Roadsters which ran at the 1963 Indianapolis 500.  Car 56 (Jim Hurtubise (1932–1989)) qualified 3^rd (150.257 mph (241.815 km/h)) but retired on lap 102 after suffering an oil leak.  Car 75 (Art Malone (1936–2013)) qualified 25^th (148.343 (238.735 km/h)) but retired on lap 18 with clutch failure.

Both Kurtis Kraft Roadsters used the supercharged, double overhead camshaft (DOHC) Novi V8 (167–183 cubic inch (2.7–3.0 litres)) which appeared on the Indy 500 grid between 1941-1966.  The Novi was famous for the howl it produced at full cry but it never achieved its potential because chassis and tyre technology didn’t advance to the point its prodigious power could successfully be handled, the adoption of an all-wheel-drive (AWD) platform (then still referred to as four-wheel-drive (4WD) which now is usually reserved for vehicles which claim some off-road capability) coming too late.  The Novi V8 and is sometimes compared to the 1.5 litre (91 cubic inch) BRM V16, another charismatic, supercharged, small displacement engine with a narrow power band.  The unusual fin on car 75 was an attempt to improve straight-line stability, an approach often used in the era before the implications of down-force fully were understood.

The Indy folklore is the adoption of the term “roadster” to describe the final era of the front-engined cars was the result of an act of subterfuge.  What defined the “Indy Roadster” was the engine and drive shaft being offset from the center-line of the car, something which allowed the driver to sit lower in the chassis thereby optimizing the weight distribution for use on (anti-clockwise) oval tracks.  It was in 1952 quite an innovation and the legend is that whenever there were visitors in their workshop, the Kurtis team covered the chassis with a tarpaulin and if asked, casually dismissed what lay beneath as “just our roadster” (then a common term for a “hot rod”, a hobby which became popular in the post-war years).  The name stuck when the car appeared, the design for a decade the dominant configuration in open-wheel oval racing although the writing was on the wall in 1961 when Jack Brabham (1926–2014) appeared at the brickyard in an under-powered mid-engined Cooper Climax which, although out-paced by the roadsters on the straights, posted competitive times because of its superior speed in the curves.  After that, the end of the roadster era came quickly and by 1965 one could manage to finish only as high as fifth, the last appearance at Indianapolis coming in 1968 when Jim Hurtubise’s Mallard retired after nine laps with a dropped piston (something as serious as it sounds).

1954 Jaguar XK120s: Roadster (open two-seater (OTS) in the UK and certain export markets; left) and Drop Head Coupé (DHC; right).  The roadsters were lighter and intended as dual-purpose vehicles which could be road-registered, driven to circuits and with relatively few changes be immediately competitive in racing.  The DHCs were based on the heavier, more luxuriously trimmed Fixed Head Coupé (FHC) coachwork while the roadsters featured cutaway doors without external handles or side windows and a removable windscreen.  Variations on this pre-war pattern was common in the British and parts of the European industry; even the early Chevrolet Corvettes were true roadsters.  

In pre-war Europe (though less so in the UK where “sports-car” or “open two seater” tended to be preferred), roadsters were often those with most rakish or flamboyant bodies, offered either by the factory or outside coachbuilders.  After the war, the term came to be restricted to what were once known as sports cars, the smaller, lighter and most overtly sporty of the line.  British manufacturers also distinguished, within a line of convertible two-seaters between lightweight roadsters and the more lavishly equipped drop-head coupés (DHC) which had features such a full-doors and side windows, neither always fitted to roadsters.  Interestingly, the early Jaguar XK120s and 140s (1949-1957) were marketed as open two-seaters (OTS) in UK and roadsters in the US, the home market not adopting the export nomenclature until the XK150 in 1958.

300 SL gullwing (1954-1957)

Although the public found them glamorous, the engineers at Mercedes-Benz had never been enamored by the 300 SL’s gullwing doors, regarding them a necessary compromise imposed by the high side-structure of the spaceframe which supported the body.  Indeed, the doors had never been intended for use on road-cars, appearing first on the original (W194) 300SL, ten of which were built to contest sports-car racing in 1952.  The W194 had a good season, the most famous victory a 1-2 finish in the 24 Heures du Mans (24 Hours of Le Mans) and this success, along with the exotic lines, attracted the interest of the factory’s US importer who guaranteed the sale of a thousand coupés, essentially underwriting the profitability of full-scale road-car production.  The sales predictions proved accurate and between 1954-1957, 1400 (W198) 300 SL gullwings were built, some eighty percent of which were delivered to North American buyers.  Curiously, at the time, Mercedes-Benz never publicly disclosed what the abbreviation "SL" stood for.  The assumption had long been it meant Sport Light (Sport Leicht), based presumably on the SSKL of 1929-1931 (Super Sport Kurz (short) Leicht) but the factory documentation for decades used both Sport Leicht and Super Leicht.  It was only in 2017 it published a 1952 paper discovered in the corporate archive confirming the correct name is Super Leicht.

300 SL Roadster (1957-1963)

 

That the sales reached the numbers hoped was good because the gullwing was expensive to produce and a certain volume was required to achieve profitability but by 1956, sales were falling.  At that time the US distributer was suggesting there was greater demand for a convertible so the decision was taken to replace the gullwing with a roadster, production of which began in 1957, lasting until 1963 by which time 1858 had been built.  Now with conventional front-hinged doors made possible by a re-design of the tubular frame, the opportunity was taken also to include some improvements, most notably a more powerful engine and the incorporation of low-pivot swing axles in the rear suspension.  The rear axle changes, lowering the pivot-point to 87mm (3.4 inches) below the differential centre-line did reduce the camber changes which could be extreme if cornering was undertaken in an inexpert manner but the tendency was never entirely overcome.  The swing axles, much criticized in later years, need to be understood in the context of their times, the tyres of the 1950s offering nothing like the grip of more modern rubber although it is remains regrettable the factory didn't, for its high-performance road cars, adopt the de Dion rear suspension it used on both road and competition cars during the 1930s.  Although manageable in expert hands, as the Mercedes-Benz Formula One drivers in 1954-1955 proved, the more predictable de Dion would likely have been better suited to most drivers on the roads.  In fairness, the gullwing’s rear suspension did behave better than many of the more primitive swing-axle systems used by other manufacturers but it needed to given that in any given situation, the Mercedes would likely be travelling a deal faster.  Remarkably, the Mercedes-Benz swing-axle arrangement lasted well into the age of the radial-ply tyre, in volume production until 1972 and used until 1981 on the handful of 600 Grossers built every year.

300 SLS (1957)

Less costly to build than the gullwing, a few hundred 300 SL roadsters were sold annually, the price tag reaching even higher in the stratospheric realm.  Unlike the lighter gullwing, the emphasis shifted from a dual-purpose vehicle suited to both road and track to one that was more of a grand-tourer.  The factory however managed to give the car one last fling at competition.  The SCCA (Sports Car Club of America), tired of the gullwing’s domination in the production sports car category, changed the rules to render it uncompetitive and, as the new roadster hadn’t yet achieved the volume needed to qualify for homologation, Mercedes-Benz built a new model: called the 300 SLS (Super Light Sport), two built to contest the SCCA’s modified production class.  Lighter, more powerful and with a few aerodynamic tweaks, the SLS won the trophy.

Job done, the factory withdrew from circuit racing although private teams would continue to campaign 300 SLs into the 1970s.  The road-going version continued with little visual change until 1963 although the engineering refinements continued as running changes, disk brakes adopted in 1961, the last few dozen built with a lighter aluminum engine block replacing the cast-iron casting.  When retired, it wasn’t replaced, the W113 (pagoda) and their successors (R107) roadsters a different interpretation of the genre.  It would be decades before Mercedes-Benz would again offer anything like the 300 SL.

190 SL (1955-1963)

The reception afforded the 300 SL prompted the US distributor to suggest a lower cost sports car would also be well-received.  The economics of that dictated the exotic features of the gullwing (dry-sump lubrication, the doors, fuel-injection) couldn’t be used so the factory instead grafted attractive roadster coachwork atop a shortened saloon car platform, the pedestrian four-cylinder engine barely more powerful than when found in its prosaic donor.  Still, the 190 SL (W121) looked the part and could be sold for well under half the price of a gullwing though even then it was hardly cheap, costing a third more than a Chevrolet Corvette and by then the Corvette had been transformed into a most estimable roadster with the addition of the new Chevrolet 265 cubic inch (4.3 litre) small-block V8.  Pleasingly profitable, nearly twenty-six thousand 190 SLs were built over an eight-year run beginning in 1955 and there were even plans for a 220 SL, using the 2.2 litre (134 cubic inch) straight-six from the “pontoon” saloon range (W120-121-105-128-180; 1953-1963) which had provided the roadster's platform.  Prototypes were built and testing confirmed they were production-ready but the continuing success of the 190 SL and capacity constraints first postponed and finally doomed the project.  After production ceased in 1962 (none were built in 1963 but the factory listed the final 104 cars as 1963 models), it wouldn’t be until the 1990s that the concept of a smaller roadster (the R170 SLK) to run alongside the (R129) SL was revived although, since the early 1970s, the SL (R107) had simultaneously been available with engines of different sizes and accordingly placed price-points.

190 SL Rennsport, Macau Grand Prix, 1957.

Though never designed with competition in mind, the factory did construct half a dozen higher-performance Rennsport (motor-racing) packages (referred to internally as the 190 SLR), the most important aspect of which was diet, the weight-reduction achieved with aluminium doors, a smaller Perspex windscreen and the deletion of non-essential items such as the soft top, sound insulation, the heater (they're surprisingly weighty devices) and bumpers.  Although never part of a major racing campaign, it did enjoy success including a class win in a sports car event at Morocco and victory in the 1957 Macau Grand Prix.

Last of the Adenauers: 300d (W189, 1957-1962) Cabriolet D (upper) & the "standard" 300d saloon (four-door hardtop).

Although some of its customers during the mid-twentieth-century (notably between 1933-1945) are understandably neglected in their otherwise comprehensive attention to history, Mercedes-Benz has always acknowledged and publicized the drivers and clients of the 1950s.  Their Formula One drivers (especially Juan Manuel Fangio (1911–1995) & Stirling Moss (1929–2020) were honored for decades after their retirements and Konrad Adenauer, the first chancellor of the Federal Republic, was even afforded the unique distinction of being the nickname for the 300 (W186 & W189, 1951-1962), the big limousine of the era which used a substantially similar engine to the 300 SL's unit.  Note that although the top image is of a convertible, it's a "cabriolet" and not a roadster.  According to Mercedes-Benz, a roadster is a two door, two seater convertible although, since the 1960s, the factory has sometimes offered the option of single (transverse) or conventional rear seat for occasional (and sometimes uncomfortable) use.  Small, these seats were really suitable only for very young children and no pretence was made that they make a roadster into a true four-seater, 2+2 the usual (generous) description.  Being Germans, during the 1930s, Daimler-Benz decided there were sufficient detail differences between the coachwork and hood (in the sense of folding roof) assemblies offered and formalized definitions of five distinct flavors of Mercedes-Benz cabriolets.

Fraulein Rosemarie Nitribitt with 190 SL and Joe der Hund.

However, in a fate shared with some of the most valued clients of the three-pointed star between 1933-1945, nor does the factory’s historic literature dwell on someone perhaps the 190SL’s best known owners, Rosemarie Nitribitt (1933-1957).  Fraulein Nitribitt was, by 1957, Frankfurt’s most illustrious (and reputedly most expensive) prostitute, a profession to which she seems to have been drawn by necessity but at which she proved more than proficient and, as the reports of the time attest, there was nothing furtive in the way she practiced her trade.  Something of a celebrity in Frankfurt, the republic’s financial centre, her black roadster became so associated with her business model that the 190SL was at the time often referred to as the “Nitribitt-Mercedes”, her car seen frequently, if briefly, parked in the forecourts of the city’s better hotels.  Unlike the contemporary connection with Herr Adenauer, the factory never acknowledged this nickname.

The lives of prostitutes, even the more highly priced, can descend to their conclusion along a Hobbesian path and in 1957, aged twenty-four, she was murdered in her smart apartment, strangled with a silk stocking, the body not found for several days.  Given Fraulein Nitribitt operated at the upper end of the market, her clients tended variously to be rich, famous & powerful and that attracted the raft of inevitable conspiracy theories there had been a cover-up to protect their interests, a rather botched police investigation encouraging such rumors.  The murder remains unsolved.  It has been suggested sales of the 190 SL suffered because of the connection, the little roadster briefly attracting the moniker “whore’s taxi” and indeed, there was a decline in the period.  However, 1956 was the first year of full-production and a second-year drop-off in sales is not unknown, gullwing production for example dropped to 308 in 1956, quite a fall from the 855 achieved the previous year and while, at least in Germany, the association with the dead courtesan may have been off-putting, without qualitative data, one really can’t say.  There was a precipitous decline in 1958 but that was the year of the worst US recession of the post-war boom where most of the drop was booked and sales anyway quickly recovered on both sides of the Atlantic.

In a coincidence of circumstances, a decade later, Fraulein Helga Sofie Matura (1933-1966) was another high-end prostitute murdered in Frankfurt, the weapon this time a stiletto (the stylish shoe rather than the slender blade).  Never subject to the same rumors the Nitribtt case attracted, it too remains unsolved.  In another coincidence, Fraulein Matura’s car was a convertible Mercedes, a white (W111) 220 SE Cabriolet.  Despite the connection, the W111 never picked up any prurient nicknames and nor did its reputation suffer, the most valuable of the W111 cabriolets now attracting prices in excess of US$300,000 for original examples while German turning houses which update the drive-trains to modern standards list them at twice that.

Helga Matura (1966) by Gerhard Richter

Gerhard Richter (b 1932) is a German visual artist whose work encompasses glass as well as aspects of both photography and painting.  Although most noted for working in illusionistic space, some of his output has belonged to various schools of realism and he seems to place himself in many of the traditions of modernism, acknowledging surrealism, the primacy of the object and the purpose of art.  Of particular interest was his 1988 series of fifteen photo-paintings (18 October 1977) depicting four members of the Red Army Faction (RAF) (better, if a little misleadingly, known in the English-speaking world as the Baader-Meinhof Gang).  Created using monochrome photographs taken mostly before their deaths, the work was an interesting exploration of time, meaning and form.

His portrait of the late Helga Matura is representative of his technique in photo-paintings, applying the practices of the Fluxus movement to material not originally created as art.  Blurred and variously in and out of focus, it takes the entirely representational image of a photograph which is then disrupted; disruptions may be for the purposes of the artist, the subject or the viewer and indeed time, the nature of the work changing whether viewed with or without knowledge of her life and death.

Crashed, California, 2005.

In 2005, Lindsay Lohan went for a drive in her Mercedes-Benz SL 65 AMG roadster.  It didn’t end well.  Based on the R230 (2001-2011) platform, the SL 65 AMG was produced between 2004-2012, all versions rated in excess of 600 horsepower, something perhaps not a wise choice for someone with no background handling such machinery though it could have been worse, the factory building 350 of the even more powerful SL 65 Black Series, the third occasion an SL was offered without a soft-top and the second time one had been configured with a permanent fixed-roof.

Fixed, Texas, 2007.

However, by 2007, the car (California registration 5LZF057), repaired, detailed & simonized, was being offered for sale in Texas, the mileage stated as 6207.  Bidding was said to be “healthy” so all's well that ends well.

Pre 1000: From the Middle English verb framen, fremen or fremmen (to prepare; to construct, build, strengthen, refresh, perform, execute, profit, avail), from the Old English framiae, fremian, fremman or framian (to avail, profit), from the Proto-West Germanic frammjan, from the Proto-Germanic framjaną (to perform, promote), from the primitive Indo-European promo- (front, forward) and cognate with the Low German framen (to commit, effect), the Danish fremme (to promote, further, perform), the Swedish främja (to promote, encourage, foster), the Icelandic fremja (to commit), the Old Frisian framia (to carry out), the Old Norse frama (to further) and the Old High German (gi)framōn (to do); the Middle English was derived from the verb.  Derived forms such as deframe, misframe, reframe, subframem unframe, beframe, enframe, full-frame, inframe, outframe, well-framed etc are created as needed.  Frame, framer & framableness are nouns, framed & framing are verbs, framable & frameable are adjectives, frameless is an adjective and framably is an adverb; the noun plural is frames.

Lindsay Lohan and her lawyer in court, Los Angeles, December 2011.

In Middle English, the sense of the verb evolved from the mid-thirteenth century “make ready” to “prepare timber for building” by the late 1300s and the meaning “compose, devise” was in use by at least the 1540s. The criminal slang (“framed”; a “frame up” etc) made familiar in popular fiction all revolved around the idea of corrupt or unscrupulous police fabricating evidence to “blame an innocent person” seems not to have been in use until the 1920s (although the dubious policing practices would have had a longer history) and all forms are thought to have been a development of the earlier sense of “plot in secret”, noted since the turn of the twentieth century, that possibly and evolution from the meaning “fabricate a story with evil intent”, first attested early in the sixteenth century.  The use of the noun in the early thirteenth century to mean “profit, benefit, advancement” developed from the earlier sense of “a structure composed according to a plan”, developed from the verb and was influenced by Scandinavian cognates (the Old Norse frami meant “advancement”).

Like its predecessor the 300 SL Gullwing (W198; 1954-1957), the Mercedes-Benz 300 SL Roadster (W198; 1957—1963) was built on a tubular space-frame.

The use in engineering “sustaining parts of a structure fitted together” emerged circa 1400 while the general sense of “an enclosing border” of any kind came some two centuries later.  Surprisingly, the familiar form of a “border or case for a picture or pane of glass” seems to have come into use only in the mid-seventeenth century while the use “human body” (ie large frame, slight frame etc) was in use by the 1590s.  Of bicycles it was used from 1871 and of motor cars by 1900 although the early use referred often to what would now be understood as sub-frames, structures which attached to the chassis to support drive-train components, coach-work etc.  The meaning “separate picture in a series from a film” dates from 1960 and was purely descriptive because the individual “frames” on film-stock resembled framed photographs attached in a continuous roll.  The idea of a frame being a “specific state” was in use in the 1660s, the “particular state” (in the sense of “one’s frame of mind”) appears in the medical literature in the 1710s.  The “frame of reference” was coined for use in mechanics and graphing in 1897; the figurative sense coming into use by at least 1924.  As an adjective, frame was in use in architecture & construction by the late eighteenth century.  The A-Frame (a type of framework shaped like the capital letter "A") was an established standard by the 1890s and a vogue for buildings in this shape was noted in the 1930s.

Faster and smaller: By 1964 the IBM 360 mainframe (left) had outgrown its cabinet (the original “main frame”) and had colonized whole rooms.  By 2022, the IBM z16 mainframe (right) was sufficiently compact to return to a cabinet.  

In computing, the word “frame” was used in a variety of ways.  The mainframe (central processor of a computer system) was first described as such in 1964, the construct being main +‎ frame and the reference simply was to the fact the core components were stored in a cabinet which had the largest frame in the room, other, small cabinets being connected with wires and cables.  Mainframes were the original “big machines” in commercial computing and still exist; incomparably good for some purposes, less satisfactory for others.  Frame Relay also still exists as a standardized wide-area network (WAN) technology although it’s importance in the industry has declined since its heyday during the last two decades of the twentieth century.  A packet-switching protocol used for transmitting data across a network, Frame Relay operates at the data link layer of the OSI (Open Systems Interconnection) model, which is the second layer in the seven-layer model.  In a Frame Relay network, data is divided into frames, which are then transmitted between network devices (such as routers), over a shared communication medium and it was this latter aspect which accounted for its widespread adoption: unlike traditional circuit-switching networks (in which a dedicated physical circuit is established for the duration of a communication session), Frame Relay allows multiple logical connections to share the same physical resources so for all but the largest organizations, the potential for cost-saving was considerable.  Importantly too, integral to the protocol’s design was the use of packet switching (which means data is transmitted in variable-sized packets (ie frames) allowing the optimal use of available network bandwidth.  Frame Relay had the advantage also of not adding layers of complexity to the network architecture, relying on the underlying physical layer for error detection and correction rather than including error recovery mechanisms (a la a protocol like X.25 which operate at the network layer).  All of this made Frame Relay scalable and adaptable to various network topologies, making it an attractive “bolt-on” for system administrators and accountants alike.  However, while it still exists in some relatively undemanding niches, the roll-out of the infrastructure required to support internet traffic mean it has substantially been supplanted by newer technologies such as Multiprotocol Label Switching (MPLS).

Pop-art painting of Lindsay Lohan in a mid-eighteenth century frame by Jean Cherin (circa 1734-1785), Paris, France.  This is an intricately carved example of the transitional Louis XV-style gilt double sweep frame, ornamented with shell centres, acanthus fan corners, and a top crested with a ribbon-tied leaf & flower cluster atop a cabochon.
