Flute

Flute (pronounced floot)

(1) A woodwind instrument consisting of a tube with a row of finger-holes (or keys) which produce sound through vibrations caused by air blown across the edge of the holes, often tuned by plugging one or more holes with a finger; the Western concert flute, a transverse side-blown flute of European origin (in colloquial use, a recorder, also a woodwind instrument).

(2) An organ stop with wide flue pipes, having a flutelike tone.

(3) In architecture or engineering (particularly the manufacture of firearms), a semi-cylindrical vertical channel, groove or furrow, as on the shaft of a column, in a pillar, in plaited cloth, or in a rifle barrel to cut down the weight.

(4) Any groove or furrow, as in a ruffle of cloth or on a piecrust.

(5) One of the helical grooves of a twist drill.

(6) A slender, footed wineglass with a tall, conical bowl.

(7) A similar stemmed glass, used especially for champagne and often styled as "champagne flute".

(8) In steel fabrication, to kink or break in bending.

(9) In various fields of design, to form longitudinal flutes or furrows.

(10) A long bread roll of French origin; a baguette.

(11) In weaving, tapestry etc, a shuttle.

(12) To play on a flute; to make or utter a flutelike sound. 

(13) To form flutes or channels in (as in a column, a ruffle etc); to cut a semi-cylindrical vertical groove in (as in a pillar etc).

1350-1400; From the Middle English floute, floute & flote, from the Middle French flaüte, flahute & fleüte, from the twelfth century Old French flaute (musical), from the Old Provençal flaüt (thought an alteration of flaujol or flauja) of uncertain origin but may be either (1) a blend of the Provencal flaut or  flaujol (flageolet) + laut (lute) or (2) from the Classical Latin flātus (blowing), from flāre (to blow) although there is support among etymologists for the notion of it being a doublet of flauta & fluyt.  In other languages, the variations include the Irish fliúit and the Welsh ffliwt.  The form in Vulgar Latin has been cited as flabeolum but evidence is scant and all forms are thought imitative of the Classical Latin flāre and other Germanic words (eg flöte) are borrowings from French.

Fluted & fluting both date from the 1610s while the verb (in the sense of "to play upon a flute") seems to bave been in use as early as the late fourteenth century.  The use to describe grooves in metalwork emerged in the 1570s and was applied to the tall, slender wine glass almost a century later although the term "champagne flute" didn't enter popular use until the 1950s.  The champagne flute is preferred by many to the coupé (or saucer) even though it lacks the (since unfortunately debunked) legend the shape of the latter was modelled on Marie Antoinette’s (1754-1793) left breast (historians gleefully recounting the tale all agree it definitely was the left).  Elegant though it is, the advantages of the flute are entirely functional, the design providing for less spillage than a coupé, something which comes to be more valued as lunch progresses to the third uncorking and the slender, tapered shape is claimed better to preserve the integrity of the bubbles, the smaller surface area and thus reduced oxygen-to-wine ratio longer maintaining aroma and taste.

Among musical instruments, there are a dozen or more distinct types of flute.  Early French flutes differed greatly from modern instruments in having a separate mouthpiece and were called flûte-a-bec (literally "flute with a beak").  The ancient devices were played directly, blown straight through a mouthpiece but held away from the player's mouth, the modern transverse (or "German") flute not appearing until the eighteenth century and the familiar modern design and key system of the concert flute were perfected 1834 by Bavarian court musician & virtuoso flautist Theobald Boehm (1794–1881), the fingering system known to this day as "Boehm system".  The architectural sense of "furrow in a pillar" dates from the mid-seventeenth century and was derived from the vague resemblance to the inside of a flute split down the middle.

One imaginative linguistic re-purposing was the use in the 1940s (apparently first in the US) of “playing the skin flute” to mean “to perform fellatio” and while still in that sense used in certain LGBTQQIAAOP circles, in general use the meaning has shifted, no describing “a male engaged in the act of masturbation”.  Use shifted to fruit, either by virtue of use at the time being almost exclusively oral rather than written (linguistically, that’s classified as an example of an imperfect echoic) or because "fruit" was then in use as a gay slur.   The nouns flute-player, fluter & flutist can be used of flute players but the preferred term is flautist.  Presumably, someone employed to add flutes to an object could be designated “the fluter” but it’s doubtful such as specialist job-description has ever been written.  Flute is a noun & verb, flutiness, flautist, flutist & fluter are nouns, fluted is a verb & adjective, fluting is a noun, verb & adjective, flutelike is an adjective; the noun plural is flutes.

In British use, one who plays the flute is a flautist (pronounced flaw-tist (U) or flou-tist (non-U)), from the Italian flautista, the construct being flauto (flute) +‎ -ista.  The -ist suffix was from the Middle English -ist & -iste, from the Old French -iste and the Latin -ista, from the Ancient Greek -ιστής (-istḗs), from -ίζω (-ízō) (the -ize & -ise verbal suffix) and -τής (-tḗs) (the agent-noun suffix).  It was added to nouns to denote various senses of association such as (1) a person who studies or practices a particular discipline, (2), one who uses a device of some kind, (3) one who engages in a particular type of activity, (4) one who suffers from a specific condition or syndrome, (5) one who subscribes to a particular theological doctrine or religious denomination, (6) one who has a certain ideology or set of beliefs, (7) one who owns or manages something and (8), a person who holds very particular views (often applied to those thought most offensive).  The alternative forms are the unimaginative (though descriptive) flute-player and the clumsy pair fluter although the odd historian or music critic will use aulete, from the Ancient Greek αὐλητής (aulētḗs), from αὐλέω (auléō) (I play the flute), from αὐλός (aulós) (flute).  The spelling flutist is preferred in the US and it's actually an old form, dating from circa 1600 and probably from the French flûtiste and it replaced the early thirteenth century Middle English flouter (from the Old French flauteor).

Daimler, the flutes and US trademark law

1972 Daimler Double-Six Vanden Plas.

Originally Belgium-based and noted for both the sporty and large bodies built for the chassis of Rolls-Royce, Lagondas, Daimlers, Bentleys and such, the coach-building house Vanden Plas was in 1946 acquired by Austin and through the British industry’s M&As (mergers and acquisitions) in the following decades, by the early 1970s it was British Leyland’s in-house coach-builder, one of its projects being to add still more luxurious appointments to the anyway lavish Daimler Double-Six.  Vanden Plas completed only 342 of the Series 1 (1972-1973) Daimler Double Sixes, the later S2 (1973-1979) & S3 (1979-1992) cars much more numerous and, in deference to the oil crisis which was the prime economic force in the decade, the S2 & S3 were available with the 4.2 litre (258 cubic inch) XK-six as were as the heroically thirsty 5.3 litre (326 cubic inch) V12.  The flutes atop the grill dated from the early twentieth-century and were originally a functional addition to the radiator to enhance heat-dissipation but later became a merely decorative embellishment.  Although some sources claim there were 351 of the Series 1 Double-Six Vanden Plas, the factory insists the total was 342.  British Leyland and its successor companies would continue to use the Vanden Plas name for some of the more highly-specified Daimlers but applied it also to Jaguars because in some markets the trademark to the Daimler name came to be held by Daimler-Benz AG (since 2022 Mercedes-Benz Group AG), a legacy from the earliest days of motor-car manufacturing and despite the English middle class often pronouncing the name as van-dem-plarr, it should said as van-dem-plass.  It's an error with the same origin as that suffered by Moët & Chandon: to English speaking ears, mow-eh sounds "more French" than mow-et. 

1976 Daimler Double-Six Vanden Plas two door.

The rarest Double-Six Vanden Plas was a genuine one-off, a two door built reputedly using one of the early prototypes, a regular production version contemplated but cancelled after the first was built.  Jaguar would once have called such things a FHC (fixed head coupé) but labelled the XJ derivatives as "two door saloons" and always referred to them thus, presumably as a point of differentiation with the XJ-S (later XJS) coupé produced at the same time.  Despite the corporate linguistic nudge, everybody seems always to have called the two-door XJs "coupés".  Why the project was cancelled isn't known but it was for the company a time of industrial and financial turmoil and distractions, however minor, may have been thought unwelcome.  Although fully-finished, apart from the VDP-specific trim, it includes also some detail mechanical differences from the regular production two-door Double-Six but both use the distinctive fluted finish on the grill and trunk (boot) lid trim; the car still exists.  The two-door XJs (1975-1978) rank with the earliest versions (1961-1967) of the E-Type (XKE; 1961-1974) as the finest styling Jaguar ever achieved and were it not for the unfortunate vinyl roof visually, it would be as close to perfect as any machine ever made.

1975 Jaguar XJC: The design perfected.  Even Jaguar's usually uncompromising originality police seem to approve.

The orthodoxy is the gluing-on of the vinyl was a necessity imposed by the inability of the paint of the era to cope with the slight flexing of the roof.  As a two-door hardtop, there was no B-pillar so the expanse of un-supported metal was larger than that of the sedans and thus more subject to higher stress-loads, resulting in the paint being subject to crazing.  Modern chemistry means suitable paints have long been available and many owners have taken the opportunity to fix the cars one visual flaw.  However, not all accept the “flexing roof” theory and claim the vinyl was a deliberate aesthetic choice, noting the 1972 Double-Six Vanden Plas (which appeared in 1972, three years before the two-door XJ went on sale) was fitted as standard with a vinyl roof, despite obviously there been no paint-related imperative.  Possibly it may have been a way of reducing interior noise but some argue it appeared just because the covering was then undeniably fashionable.  The inexcusable lapse in taste had been seen (then using leather) as early as the 1920s but it was in the US in the mid-1960s the motif hit the mass-market to attract those who wanted “a convertible’s rakish vibe” but needed something more practical; things soon got out of hand, the trend spreading to the UK and Australia.  For up-market models, the Australians even emulated the US practice of the “padded vinyl roof” which was a bad idea made worse the closer one got to the tropics, the foam in the “vinyl-metal sandwich” trapping moisture and leading quickly to rust.  The Europeans proved commendably resistant and by the 1980s the moment had passed in the UK and Australia but the Americans doubled-down and, until the mid-1990s, Detroit’s designers devoted much energy to styling elaborate variations on the theme, the marketing department doing its usual bit by labelling them with fanciful names.

Using one of his trademark outdoor settings, Norman Parkinson (1913-1990) photographed model Suzanne Kinnear (b 1935) adorning a Daimler SP250, wearing a Kashmoor coat and Otto Lucas beret with jewels by Cartier.  The image was published on the cover of Vogue's UK edition in November 1959.

Although Daimlers had, in small numbers, been imported into US for decades, after Jaguar purchased the company in 1960, there was renewed interest and the first model used to test the market was the small, fibreglass-bodied roadster, probably the most improbable Daimler ever and one destined to fail, doomed by (1) the quirky styling and (2) the lack of product development.  It was a shame because what made it truly unique was the hemi-head 2.5 litre (155 cubic inch) V8 which was one of the best engines of the era and remembered still for the intoxicating exhaust note.  The SP250 was first shown to the public at the 1959 New York Motor Show and there the problems began.  Aware the small sports car was quite a departure from the luxurious but rather staid line-up Daimler had for years offered, the company had chosen the pleasingly alliterative “Dart” as its name, hoping it would convey the sense of something agile and fast.  Unfortunately, Chrysler’s lawyers were faster still, objecting that they had already registered Dart as the name for a full-sized Dodge so Daimler needed a new name and quickly; the big Dodge would never be confused with the little Daimler but the lawyers insisted.  Imagination apparently exhausted, Daimler’s management reverted to the engineering project name and thus the car became the SP250 which was innocuous enough even for Chrysler's attorneys and it could have been worse.  Dodge had submitted their Dart proposal to Chrysler for approval and while the car found favor, the name did not and the marketing department was told to conduct research and come up with something the public would like.  From this the marketing types gleaned that “Dodge Zipp” would be popular and to be fair, dart and zip(p) do imply much the same thing but ultimately the original was preferred and Darts remained in Dodge’s line-up until 1976, for most of that time one of the corporation's best-selling and most profitable lines.  The name was revived between 2012-2016 for an unsuccessful and unlamented small sedan.

Leaper, growler and flutes on US market 1999 Jaguar Vanden Plas (X308).  The retractable, solid-timber picnic tables in the back of the front seats were much admired.

Decades later, US trademark law would again intrude, this time on Jaguar’s low-volume business of selling Daimlers in the US.  There, the company had after 1967 ceased offering the Daimler because, it being clear the trickle of safety & emission regulations was soon to be a flood, with capital scarce, it was decided resources needed to be devoted to compliance and one form of economy was to re-allocate the funds absorbed by maintaining Daimler as a separate brand, most of which were spent on advertising.  In Stuttgart, the Daimler-Benz lawyers took note and decided to reclaim the name, eventually managing to secure registration of the trademark and Daimlers have not since been available in the US.  However, there was still clearly demand for an up-market Jaguar and so the Sovereign name (used on Daimlers between 1966-1983) was applied to Jaguar XJ sedans which, although mechanically unchanged, were equipped with more elaborate appointments.

Sales of the up-market Sovereign were good and the profit margins fatter so the US market also received some even more luxurious Vanden Plas models and during the XJ’s X308 model run (1997-2003), the VDP cars were fitted with the fluted grill and trunk-lid trim as an additional means of product differentiation; it would be the last appearance of the flutes in North America and the only occasion on which the leaper and growler were used in conjunction with them.  Although some might dismiss the interior fittings of the Vanden Plas models as “bling”, there were nice touches.  The ones based on the X308 featured the fold-down picnic-tables once so beloved by English coach-builders (the affection in the 1960s trickling down to the middle-class as they began to appear on blinged-up mass-market vehicles) but, rather than the usual burl walnut veneer, the pieces were of solid timber.  The factory seems never to have discussed the rationale but it may be it was cheaper to do it that way, the veneering process being labor-intensive.

Jaguar became aware the allure of the flutes was real when it emerged a small but profitable industry had emerged in the wake of the company also ceasing to use the Daimler name in European markets (by the 1990s, it was only in the UK, Australia & New Zealand that they remained available).  Entrepreneurial types, armed with nothing more than a list of Jaguar part-numbers, had created kits containing the fluted trim parts and the Daimler-specific badges, these shipped to dealers or private buyers on the continent so Jaguar XJs could become “Daimlers”.  Being factory-supplied parts of no mechanical significance, their use did not affect on warranties or insurance rates (though owners were required to inform the registration authorities the badges had changed) so, unlike many after-market modifications, it was a hassle-free process.  Jaguar took note of this uptick in the Daimler-demand curve and decided to meet it with supply, re-introducing the marque to Europe.  Because, in effect, they were doing only what was being done by those buying the kits, it was one of the industry's cheapest and quickest brand resurrections, Germany and the Netherlands proving especially receptive markets.  One notable owner of a real LWB (long wheelbase) Daimler V8 (X308) was the Dutch academic and politician Pim Fortuyn (1948-2002), assassinated by a left-wing environmentalist and animal rights activist during the 2002 national election campaign.

Sanpaku

Sanpaku (pronounced san-pach-ew)

An eye in which the sclera (white of the eye) is visible on three sides of the iris rather than the usual two (left & right).

Pre 1700s: A borrowing from the Japanese 三白 (sanpaku) (three whites) or 三白眼 (sanpaku gan) (three-white eyes).  Sanpaku is a noun and sanpakuish is an adjective; the noun plural is sanpakus.

Sanpaku (三白) (three whites) & Sanpaku gan (三白眼) (three-white eyes) are Japanese terms from traditional Chinese & Japanese medicine and they describe the “condition” in which the white of the eye is visible either above or below the iris when looking straight ahead.  Although the word was popularized by Japanese educator and nutritionist Nyoichi “George” Ohsawa (1893–1966) when he published the book You Are All Sanpaku in 1965, the idea had existed in oriental medicine probably for centuries although it’s impossible accurately to determine its origin.  It was mentioned in the diaries of at least one nineteenth century US Navy physician but attracted no interest in the West until the release of Ohsawa san’s book.  In Western medicine the phenomenon is described as “lower scleral show” or “inferior scleral show”, terms which are merely descriptive because (1) it’s something thought within the range of normality, (2) is indicative of no other mental or physical states and thus (3) is generally not considered a medical condition requiring treatment and is attributed variously to (3a) normal variation in eyelid anatomy, (3b) transient facial expression or gaze direction, (3c) traumatic injury or (3d) age-related tissue changes.  There are orbital or eyelid conditions (the best known being a thyroid-related eye disease causing lid retraction) which can induce a sanpaku-like appearance but instances are vanishingly rare.  In short, the medicalization of sanpaku is thought a product of superstition so predictably, on social media, sanpaku eyes seem to have a cult following.

In You Are All Sanpaku, Ohsawa san described sanpaku as a condition which indicated physical and mental imbalances and discussed its significance in relation to diet and overall well-being.  Historically, sanpaku is believed to have entered oriental medicine from the Japanese practice of “face-reading” and those with eyes observed thus were considered ill-fated and destined for a life filled with misfortune, culminating often with an early demise.  It gained a following on social media by the usual means: celebrity association.  Diana, Princess of Wales, President John Kennedy & Marilyn Munroe, all of whom died young, were all sanpakus and as Ohsawa san warned in You Are All Sanpaku: the eyes indicate someone's fate, signifying imminent danger or an “early and tragic end.”

The original basis of “face reading” isn’t known but as a diagnostic tool it focused on the matter of “balance”, something important also to the physicians of Antiquity who identified the “four humors”: flegmat (phlegm), sanguin (blood), coleric (yellow bile) & melanc (black bile) which were the causative agents of the four personality types, the phlegmatic, the sanguine, the choleric & the melancholic.  In the East, signs of sanpaku meant a man’s whole system (physical, physiological and spiritual) was out of balance, something caused by sins committed against the order of the universe, accounting for his sickness, unhappiness or insanity.  Ohsawa san noted that in the West, such folk had come to be called “accident prone” and they were the ones who should take note of the warning from sanpaku, nature’s tap on the shoulder.  A practical author of self-help texts, Ohsawa san recommended sanpaku eyes should be treated with a macrobiotic diet, focusing on brown rice and soybeans, something on which he had real expertise as the founder of the macrobiotic diet.

By their sanpaku you shall know them: Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945, left), crooked Hillary Clinton (b 1947; US secretary of state 2009-2013, centre) and cult-leader Charles Manson (1934-2017, right).

Interestingly, the beliefs about sanpaku are culturally variable although universally it’s held the condition determines one's fate.  In the Japanese tradition those consequences are ill fate and misfortune while the Chinese associate sanpaku with good luck and wealth and this divergence has interested cultural anthropologists who study the symbolism and mythologies of different societies.  The tradition divides the eyes into "yin sanpaku" and "yang sanpaku", the roots of this the ancient Chinese concept of yin & yang, representing the duality of opposing yet complementary forces in the universe.  Yin and Yang are fundamental concepts in Chinese philosophy and represent complementary and interconnected aspects of the universe. Yin is associated with qualities such as darkness, femininity, passivity, and coldness, while Yang is associated with light, masculinity, activity, and warmth. They’re seen as opposing forces that are in a constant state of dynamic balance and they exist within all phenomena, including human physiology, nature and society.  In this they differ from the (wholly un-related) concept in particle physics of matter and anti-matter.  Matter is the familiar stuff which is much of the physical universe (particles such as protons, neutrons, and electrons) while anti-matter consists of particles with the same mass as their matter counterparts but carrying an opposite charges.  When matter and anti-matter particles come into contact, they can annihilate each other, releasing energy.  Ying and Yang, mutually dependent, live in peaceful co-existence.

The Mean Girls (2004) crew demonstrate the range:  Rachel McAdams (b 1978, far left) & Lindsay Lohan (b 1986, centre-left) are in the part of the population who are either not sanpakus or the effect is imperceptible.  Lacey Chabert (b 1982, centre-right) is in the group with a separation around 1 mm while Amanda Seyfried (b 1985, far right) displays up to 2 mm depending on her expression.

Before it became a meme, this was an obscure photograph which until the twenty-first century had appeared only in some specialist history texts but as the internet achieved critical mass, memes became a thing and Mussolini’s sanpaku eyes were a gift for the meme-makers, most captions suggesting the Duce may have had a sudden premonition of his own unfortunate end although others offered: “I feel naked without a moustache”, “I think I have imposter syndrome”, “Oh God, I just pooped my pants”, “I know one of these men is a Freemason but I don't know which” and “I wonder if they can tell I've smoked some weed”.  However, although not noted as a mystic, he may have sensed another's impending death, “sitteth at the right hand”, Andrew Bonar Law then having only months to live.

Princess Beatrice, Mrs Edoardo Mapelli Mozzi (b 1988).  Until she appeared at a royal wedding in the fascinator she made famous (some humorless souls would have said infamous), she was most noted for her lovely sanpaku eyes.

In Japanese face reading, yang sanpaku eyes (white part visible above the iris) reveal a person's dark and sinister nature, the eyes indicating the unstable mental state suffered by individuals exhibiting uncontrollable aggression, such as psychopathic murderers or serial killers.  Yin Sanpaku Eyes (sclera visible below the iris) signify a different physical or mental imbalance, one caused by the abuse of drugs, alcohol, and sugar which disrupt the body's equilibrium.  Although discouraged by all in the profession except the odd, entrepreneurial cosmetic surgeon, treatment options are available to “correct” scleral show and the most effect treatment is aesthetic plastic surgery, specifically the procedure called blepharoplasty, which can correct the appearance of the eyes.  The construct of blepharoplasty was blepharo- +‎ -plasty.  Blepharo- was from the New Latin, from the Ancient Greek βλέφαρον (blépharon) (eyelid; a feature resembling an eyelid) and -plasty was from the Ancient Greek πλαστός (plastós) (molded, formed) which now has the special meaning in medicine meaning "repair, restoration or re-shaping of part of the body with a surgical procedure".

Casual observation suggests sanpaku eyes are far from rare and there are said to be three classes: (1) those with at least a .25 mm (.0098 inch) space between the iris and the upper and lower eyelids, (2) those with a separation of 1 (.0394 inch) mm and (3) those with a gap of 2 mm (.0787 inch) or more.  The concition need not manifest as something symmetrical (in the vertical axis), the two elements being (1) Sanpaku inferior: white visible below the iris and (2) Sanpaku superior: white visible above the iris, the latter said often induced when a subject is frightened or physiologically stressed).  However although “estimates” have been published, neither the prevalence of the condition nor the distribution within the three (unofficial) groups have ever been the subject of a reputable epidemiological study; because “sanpaku eyes” is not a recognised medical or anthropometric category; funding would thus be hard to secure although, as a purely observational and statistical exercise, presumably not many ethics departments would much be troubled.  So, lacking a defined diagnostic entry, there is no standardised measurement threshold and estimates of prevalence are thus almost certainly speculative and thus unreliable.  Those with sanpaku eyes should not too much dwell on the numbers and instead flutter their eyelashes and enjoy the admiring glances.

Humans are not the only species with a sclera but we are untypical in it being so visible.  That humans even have white scleras has interested linguistic anthropologists, evolutionary biologists and other researchers, some offering the Cooperative Eye Hypothesis which suggested the distinctive appearance evolved as a mechanism with non-verbal communication could be enhanced.  According to this conjecture, the high visibility of the iris & pupil against the white background allows an interlocutor more easily to track eye movements, helping individuals to understand where others are looking during interactions.  Observational studies revealed the way humans and other great apes move their heads and eyes in different ways, humans relying more on eye movements than head movements to see where someone else is looking.  Apes, without the white component in their eyes, tend more to move the whole head.  Not all support the "cooperative eye" faction but it’s an interesting approach to understanding the evolutionary significance of the human eye's appearance and the sophistication of communication is certainly a noted difference between humans and apes.

Seeing the whites of the eye: a gree-eyed cormorant taking lunch.

The phrase “don’t shoot until you see the whites of their eyes” comes of the military and was an instruction to infantry in the age of the musket to delay firing until the target was within close range, the rationale being (1) accuracy would be enhanced and (2) the projectile (musket ball) would strike with greater energy, thus increasing the effectiveness (measured in the casualty & death rates).  It’s often attributed to Colonel William Prescott (1726–1795) shouting it to his troops at the Battle of Bunker Hill (1775) during the American Revolutionary War (1775-1783) but according to Phrase Finder, the origins lie at least 32 years earlier.  On 27 Jun, 1743, during the Battle of Dettingen (fought in Bavaria as one of the "footnote engagements" of the War of the Austrian Succession (1740-1748)), the resourceful Scot Lieutenant-Colonel (later Lieutenant General) Sir Andrew Agnew of Lochnaw (1867-1761) 5th Baronet) departed from military orthodoxy when, responding to a French cavalry charge, adopted a novel tactic he’d devised, keeping his men not in the conventional square formation to meet the charge head on but having the two centre companies divide from the centre, falling back from the outer markers, thereby compelling the French to gallop through a withering crossfire.  It was potentially a high-risk strategy but he’d trained his troops well the French cavalrymen obediently threaded the needle, suffering heavy losses.  Tacitly acknowledging the danger presented by his innovation, Sir Andrew’s succinct instruction to his brigade had been: “Dinna fire till ye can see the whites of their e' en . . . if ye dinna kill them they'll kill you.”

If the human eye lacked a white sclera it would mean the “messaging” in facial expressions (a non-verbal clue in communication) would have evolved a little differently; Paris Hilton (b 1981) illustrates (digitally altered image).  Ms Hilton has brown eyes but often wears blue contact lens.

As far as is known, all living creatures on Earth came ultimately from a single event which can be said to be the origin of life because at this time, there is no evidence of other living things anywhere in the universe.  Everything else is speculative; life may have started (or arrived) here many other times but for whatever reason not thrived and around the universe there may be many forms of life; some may be more advanced than us or we may be unique in our scientific and technological mastery.  The single point of origin is why we share elements of DNA (Deoxyribonucleic acid, the so-called “building-blocks of life”) with our cats, dogs, goldfish and bananas so, unsurprisingly, in living creatures, eyes are common, often in pairs but unlike those in humans, not all are out-growths of a brain although, in many of the lineages of the Metazoa they are neurally derived and remain tightly integrated with the central nervous system.

A nice pair of boobies.  Charmingly, blue-footed boobies are known to be monogamous, pairs often staying together for life.  Like us, birds are two eyed vertebrates although except for the old outlier (like owls) their eyes, for good reasons, shifted to the sides.  Note how the booby’s eye differs from that of a human.

As a general principle it all depended on the developmental origin and phylogeny (the evolutionary history of groups of organisms).  In vertebrates (mammals, birds, fish etc), the eye evolved as an evagination (a growth outward) of the forebrain during embryogenesis (the process by which an embryo is formed and develops).  Cephalopods (octopus, squid etc) differ in that while the optic lobes of the brain are large and closely connected, the eye is not literally a brain protrusion; thus, while neurally integrated, the eyes are not brain outgrowths.  Arthropods (insects, crustaceans and such) have compound eyes formed from ectodermal (of the The outermost of the three tissue layers in the embryo of a metazoan animal) tissues which connect to the brain via optic nerves and are thus also neurally connected but not developmental extensions of the brain itself.  Many cnidarians (such as the box jellyfish) possess complex lens eyes but lack a centralized brain, their eyes peripheral sensory structures connecting to nerve rings rather than a true brain.  Many invertebrates have relatively simple photoreceptors which can be thought of as “eyespots” which can be distributed across body tissues, the best contemporary comparison probably the sensors now so ubiquitous in electronic devices.

Boobies, one step at a time.

A booby is a seabird in the genus Sula, part of the Sulidae family.  Boobies are closely related to the gannets (Morus), which were formerly included in Sula, the genus created in 1760 by the French naturalist Mathurin Jacques Brisson (1723-1806).  The name was derived from súla, the Old Norse and Icelandic word for the other member of the family Sulidae, the gannet.  The English name booby was based on the Spanish bobo (stupid) as the tame birds often landed on board sailing ships, where they were easily captured and eaten.  As well as a popular addition to the diet of sailors for whom meat other than fish was a rarity, it was fortuitous for many, the Admiralty's archives revealing boobies often mentioned as having been caught and eaten by shipwrecked sailors.

Mr Andrew Mountbatten Windsor in police car, under arrest, February, 2026.

If humans had eyes free of a white sclera (like the booby and many birds), our appearance would be quite different, illustrated by a digitally edited image of (the former prince/duke/admiral etc) Andrew-Mountbatten Windsor (b 1960), rendered as a cartoon by Vovsoft.  However, the use of that image to demonstrate the point may not have been the best choice because, in the original, his expression didn’t appear greatly different.

As well as charming eyes, boobies also have interesting feet.  The distinctive blue feet (the result of pigments ingested from their diet of fish) also play a part in the bobby’s mating ritual although not exactly in the podophilic sense familiar in a sub-set of humans.  In the spring mating season, the bird’s feet become a bright turquoise blue and, to demonstrate their health and vitality, conspicuously they will display them to potential partners.  The job done, as their eggs hatch, the blue hue fades to something less vivid.  One aspect of their behaviour which amused the ornithologists who first observed it was that if among fishers unloading their catch, it tossed a small fish from the by-catch, a booby will take it and waddle off somewhere to enjoy it in solitude rather than gulping it down as in common in many species.  Like penguins, although ungainly on land, they are skilled plunge divers which used their streamlined bodies and air sacs “fly” through the water, catching their prey at high speed and they hunt in "packs", coordinating their movement to maximize the catch.  Boobies have been recorded diving from as high as 90 m (300 feet), their speed upon entry estimated at around 100 km/h (60 mph).

1350–1400: From the Middle English knobe & knobbe, thought almost certainly from a Scandinavian or German source and probably at least influenced by the Middle Low German knubbe & knobbe (knob; knot in wood; bud), the Middle Dutch knobbe & cnoppe, the Dutch knop (knob, button, bud), the Old Frisian knopp & knapp, the Old High German knopf (bud, pommel of a sword, knot, loop), the Middle High German knospe, the German Knopf (button, knob) & Knospe (bud), the Danish knap (button) & knop (knob, button, bud) and the Old Norse knyfill (short horn).  Most etymologists seem most convinced by it being a variant of the Proto-Germanic knappô (knob, lump) & knuppô (lump, clod), both among the “kn-” words related to knudaną (to knead).  Probably related were the Middle English knap & knappe (small projection, knob (in the sense of “button, tassel, tuft etc”), hill, hilltop etc)), from the Old English cnæp & cnæpp (summit, top), which may in some way be linked with the Old Norse knappr (small projection, knob (in the sense of “button, head of a stick etc”)) (and from which English gained knop), the source again the Proto-Germanic knappô.  The meaning “knoll, isolated round hill” seems first to have appeared in the 1640s and, perhaps surprisingly, no instance of “doorknob” has been found prior to 1829 although the word may have been long in oral use (drawer-knob, window-knob etc all followed).  Knob is a noun & verb, knobless is a noun, knobbed & knobbing are verbs, knoblike & knobby are adjectives; the noun plural is knobs.

In idiomatic use, the phrase “same to you with knobs (sometimes “brass knobs”) means “the same to you but even more so” (used typically in response to an insult or slight).  A “knob-twiddler” can be an informal term for a technician or console operator whose job entails adjusting electronic devices via knobs but it can also describe anyone whose role seems either unimportant or not particularly demanding.  As machinery and later electronics became an increasingly ubiquitous part of life, so did knobs and as early as the late nineteenth century the humorous “knobologist” had been coined to describe both those designing the system and the “knob-twiddlers” using them; the discipline of design was of course dubbed “knobology” and that remains a core component of ergonomics, exploring imperatives such as placement, size, tactility and labelling, all of which influence the functionality of controls on an instrument as relevant to their application.  The knobologists deeply were implicated in convenient physical switches, knobs and buttons disappearing from cars and re-imagined virtualizations on inconvenient touch-screens.  Such has been the reaction (including the realization the change made driving more accident prone) that the tactile controls are making a welcome comeback.  The now archaic “knob-thatcher” was an affectionate term for a maker of wigs while the more modern “surfer's knob” was slang from the sport, describing a hard bump or nodule on a surfer's knee, shin or ankle, resulting from recurrent contact with their surfboard.  In engineering and metallurgy, “to knobble” was (1) to render a surface with a knobbly finish and (2) to produce wrought iron by treating semi-refined puddled iron on a hearth before shingling, a specialized device in the business being the ominous sounding “knobbling furnace”.

Gay men supporting lesbians at the first “Dyke March”, Washington DC, April 1993.  The sign held by the protester at the far left uses the compound word for which the euphemisms “knob polisher” & “knob-gobbler” were coined.

Because knob was popular slang for penis, a number of derived terms predictably emerged.  A “knob polisher” or “knob-gobbler” was “one who gives fellatio”.  “Knob rot” was a reference to certain sexually transmitted diseases contracted by men, the acute condition “galloping knob rot” describing a rapidly progressing or uncontrollable variant of the condition.  A “knob job” was the act of fellatio.  “Knob cheese” (the terms “cock cheese”, “dick cheese” and (in context) even “cheese”) was vulgar slang for smegma (a whitish sebaceous secretion that collects between the glans penis and foreskin or in the vulva).  “Knob jockey” must however be used with care because it has variously been applied to (1) gay men, (2) promiscuous straight women and (3) promiscuous straight men; context thus matters.

Interior of Porsche 917K with cool (in both senses of the word) balsa-wood shift knob.  The obviously "fake" passenger bucket seat was installed to comply with the rules in sports car racing.

To this day, the myth persists the balsa-wood gear-shift knob used in the Porsche 917 was there as a “weight-saving measure”.  While it’s true the small knob was light, the difference between it and the aluminum or magnesium units the company had fitted to earlier race cars would have been so insignificant it’s doubtful it would have equalled a gulp of coffee the driver may or may not have enjoyed.  The stylish timber piece was however not a decorative flourish but a legitimate engineering solution to ameliorate one manifestation of “chronic heat soak”.  In 1969, the 917 was a radical advance which, Dreadnought-like, rendered all other cars in its class instantly obsolescent but the flat-12 engine (Porsche’s first in the configuration) radiated so much heat it was difficult to manage.  In a tradition it would not for decades abandon, Porsche continued to use air-cooling for the engine (which really means “oil cooled” about as much) and it ran hot; between that heat source and the gear level was a unbroken metal path, each component a most efficient conductor.  During endurance racing (some events conducted over 24 hours), cockpit temperatures could reach what doctors would rate as “extreme”.  The metal lever was just one of the sources of this heat and the knob (which sat next to the driver’s knee) needed to be grasped by the driver, often many times a minute; were it to become so hot it caused pain, it would have been safety issue.  Although in 1969 the space-age was at its zenith, the materials which could have made a driver’s gloves close to heat-proof were not then commercially available so they gained much of their protective quality from thickness but the problem was they could be only so thick because a driver needed still to handle a highly-geared steering wheel and operate the many knobs and switches within arm’s reach.  Balsa-wood, with its very low thermal conductivity was ideal because while not exactly cool to the touch after a few hours on the track, it never got so hot it felt unpleasant.  It also had adequate strength for its task; a gear-lever knob does not bear structural loads and, being Porsche, it received the same careful attention as every other component, each one precisely machined to exact dimensions before receiving two coats of clear lacquer.  Most variants of the 917 used the Balsa-wood part although when (as the “Turbo-panzers”) the most powerful of the breed appeared in the Can-Am (for Group 7, unlimited displacement sports cars) a metal knob was fitted, made possible because Group 7 was for open cars and significantly that reduced cabin temperatures.  By the late 1970s when the space age had made available materials (phenolic plastics, composites etc) with superior insulation qualities, the need to resort to a balsa-wood knob vanished but the visual appeal remained and in the aftermarket, 917-style knobs remain widely available.

1959 Ford Fairlane Galaxie 500 Sunliner with suicide knob (on steering wheel at 10 o'clock).

“Suicide knob” was the most popular name for the device attached to a vehicle’s steering wheel which facilitated easier “single arm steering”.  The idea dated from the days before the almost universal fitting of power-steering and the things became popular in the US in the US in the 1950s and 1960s as even low-priced cars became heavier; for some drivers, they were invaluable when manoeuvring at low speed, especially when reversing.  They were known also as the “necker knob”, “wheel spinner” and “granny knob” but the most correct term was “Brodie Knob”, the name in honor of Steve Brodie (1861–1901), an apparently rather raffish gentleman from New York City who, as a last resort in 1886 after losing everything gambling, staged a stunt in which he jumped off the Brooklyn Bridge (site of a good many suicides), the lure a sum of money he was bet although the details of that are murky.  Mr Brodie anyway survived to collect on the wager and, on the basis of the notoriety gained, began performing other dare-devil acts for even more money.  So the jump from the Brooklyn Bridge was a good career move although the consensus now is it was a cunning stunt (ie a scam), a weighted dummy the real diver with Mr Brodie entering the water from the safety of the shoreline.  In fairness, at least some of his subsequent dangerous stunts were verified by observation and he parlayed his fame into a successful career in business, becoming a noted philanthropist and dying a rich man.

The invention of the suicide knob generally is credited to Joel Thorp of Wisconsin but similar devices had for centuries been in use on land and water.  What Mr Thorpe described in the supporting documents for what was issued as US Patent 2,101,519 STEERING WHEEL SPINNER KNOB (Dec 7, 1937) was an “improvement” of the concept:

“The present invention relates generally to improvements in appliances for facilitating manipulation of the steering wheels of vehicles, and relates more specifically to improvements in the construction and operation of spinner knob attachments co-operable with the peripheral rims of steering wheels or the like in order to effect more convenient and rapid operation of such wheels under certain conditions of use.  Generally defined, an object of my present invention is to provide an improved steering wheel spinner knob which is simple in construction and highly efficient in use.”

A young lady wrapping practiced fingers around the timber shift knob in 1970 Maserati Indy (Tipo 116, 1969-1975).  In the era, it was fashionable in Italian exotica for the knob and steering wheel rim to match (ie in leather or wood).

Although widely used on tractors, heavy transport vehicles and such, it was in the 1950s as cars in the US became heavier the suicide knobs gained popularity and some of that was due to reasons Mr Thorp probably never envisaged.  One receptive market was males aged 17-25 (a crew infamous for many reasons) who found the combination of suicide knob and bench seat made an idea ecosystem, enabling one hand to be used steer the vehicle while the "free" arm could wrap around the girlfriend (or alternative) who affectionately was resting her head on the driver’s shoulder.  In this arrangement, a driver’s attention more easily could be divided between her and the road.  It was also males aged 17-25 who were the core of the hot-rod community which began as a West Coast phenomenon (induced by a critical mass of the right demographic, available disposable income and a good supply of cheap, used cars which easily could be modified as desired) and they found suicide knobs the best way to “do a half donut” (a spin of one’s hot rod through 180^o), the trick being to grip the knob and then suddenly turn the wheel while applying full throttle, resulting in a loud, spectacular maneuver, made the more pleasing for the driver by him having “left his mark” in strips of runner on the road.  This, the hot rodders called “spinning a brodie”, a variant on the earlier “doing a Brodie” (a dangerous or otherwise inadvisable act) which entered the language after the nation-wide publicity which followed Mr Brodie’s alleged leap from the Brooklyn Bridge.  In the era, a Brodie Knob was as essential a piece of equipment as one’s packet of unfiltered Camel cigarettes or pair of fluffy dice hanging from the rear-view mirror.

1962 Maserati 3500 GTi.  Some Maserati 3500 GTs (Tipo 101, 1957-1964) had the unusual feature of having front and rear quarter-vents fitted to the same door; they were opened and closed using knurled, stainless steel knobs.

The dark appellation “suicide knob” was bestowed because (1) the devices came to be associated with accident-prone drivers (the “males aged 17-25” cohort prominent in the statistics) who probably did use the things to engage in “risk-taking” and (2) by virtue of their location (by default affixed to the upper quadrant) on the wheel, they were a genuine danger in accidents and, in an era of non-collapsible steering columns, tales of them penetrating the eye socket, causing irreparable loss of vision and traumatic brain injury, were legion.  The crusading US lawyer Ralph Nadar (b 1934) is criticized for much but the contribution his book Unsafe at Any Speed (1965) made to reducing the death toll on the roads cannot be under-estimated and the effect was world-wide because the rest the industry eventually followed the lead of the US legislation which came in the book’s wake.  In the US and elsewhere, change was of course resisted but it came and while it’s not possible to estimate how many deaths and often gruesome injuries the reforms prevented, no one denies it’s a big number.  The suicide knob was one minor casualty of the movement and in road-registered vehicles, in most jurisdictions (although some US states remain permissive), such devices are permitted only for specialized (often low-speed) vehicles and if used by drivers with some disability which precludes the use of conventional controls.

Another to make a life-saving contribution to reducing the road told was George Hurst (1927-1986; founder of his eponymous company) whose great legacy to humanity was the “Jaws of Life”, a hydraulic cutter he first developed in 1961 after being shocked at how long it sometimes took to extract the driver from the crumpled wreck of a race car.  The great advantage of the “Jaws of Life” was that it worked like a very powerful pair of scissors, avoiding the showers of sparks produced by mechanical saws, always a risk to use in areas where fuel is likely to have been spilled.  The basic design came to be used in hydraulic rescue devices worldwide and quite how many lives have been saved by virtue of its use isn’t known but again, it would be a big number.

Two decades of progress: Shifter for the two-speed Powerglide automatic transmission in 1953 Chevrolet Corvette (left) and a classic spherical shift knob in 1972 Chevrolet Corvette LT1.  The delicate-looking shifter in the 1953 Corvette seems modest but the location was a world-first for an automatic and was efficient because the location (between the driver’s seat and transmission tunnel) provided the shortest possible path to the linkage.  As late as 1964, Chrysler used a similar apparatus in the 1964 300K.

However, before the Jaws of Life, Hurst was already famous in the vibrant sub-culture which was at the times also known for its propensity to purchase and install suicide knobs.  Hurst produced “shifters” which were the assemblies connected to a transmission, used by the driver to “change gears” and they proved instantly popular which may seem strange given every manufacturer at the time included a shifter with every vehicle.  However, beginning in the late 1930s, the US manufacturers had begun moving from centrally located, floor-mounted levers to units on the steering column because it made for better packaging efficiency in the cabins, then optimized for bench-seats with three-astride seating.  That move achieved the goal but with the linkage between lever and gear-changing mechanism now longer and making more turns, some precision in the shifting was lost and column shifting (the once almost universal “three on the tree”) was less conducive to an enthusiastic driving style (such as that of the “suicide knob equipped” crowd).  It was in the 1950s the taste for floor-shifts like those in European sports cars began to gain critical mass and even though the 1953 Chevrolet Corvette was hardly a sports car in the tradition of MGs, Fiats and such, it’s notable Chevrolet from the start installed a floor shift for the (two-speed!) Powerglide automatic transmission; it may not have been a sports car with a “four-on-the-floor” but it had a floor-shift so there was that.  Automatic transmissions in mass-produced cars was then something of a novelty barely a decade old and the Corvette’s floor shift was apparently a world-first.

A butter curler producing curls.  Generally, the curlers come in large and small, respectively producing a curl notionally equivalent to a dollop or a knob (half-dollop).  In the kitchen however, knobs and dollops are what the chef decides they are.

Four-speed manual transmissions began to appear in Detroit-made cars in the late 1950s and within half a decade George Hurst’s shifters were close to obligatory for any racer (authorized or not) seeking “street cred” and it wasn’t a confected image, the Hurst shifters demonstratively superior without being excessively expensive.  So stellar did their reputation become even GM (General Motors) relaxed their long-standing ban on other brand-names being associated with their products and made a feature of one being standard equipment of the 1964 Pontiac GTO, the car credited with being “the first muscle car” and such was the success in 1965 the shifter’s handle was even permitted to be embossed: HURST.  Soon, other manufacturers actively were seeking co-productions.  George Hurst’s path to market domination was shockingly simple and might have come from a textbook: (1) a perfected design, (2) skilful engineering in development, (3) high quality in production and (4) an attractive price, a combination of elements with great appeal for buyers and manufacturers alike.

Hurst’s dual-gate automatic transmission “His and Hers” shifter with conventional apparatus “for the automatic minded little lady” and a performance-oriented configuration offering manual control for the “man who really wanted a 4-speed standard stick but bought this extra just for her.”  Note the unfamiliar shift pattern, the now universal PRNDL not an industry standard until 1965, the year before it was demanded by regulations.  From the early days of automatic transmissions in the 1940s, reverse had been directly adjacent to Low, allowing drivers more easily to emulate what was done with manual transmissions when a “rocking” was being induced to try to free a vehicle from mud or snow.  It was a quirk of the age and, because reliability was not then what decades later came to be expected, the early transmissions included a second (rear) fluid pump to permit push/tow/hill starts.  Probably, not many much dwelt on the shape of the knob Hurst put atop the His and Hers” shifter but in geometry it would be described as an oblate spheroid with two parallel planar truncations.  Now easily modelled in software rendered with a 3D printer, perfecting a shape like this for production used to absorb much time on the drawing board and in the creation of prototypes.  A spheroid is an ellipsoid generated by rotating an ellipse about one of its principal axes which, if “stretched” along one axis becomes a prolate spheroid (ie elongated and something like a rugby ball).  If slightly flattened along the axis of rotation, it’s an oblate spheroid (like planet Earth which isn’t quite a pure sphere) but the His & Hers knob, having a slight elongation along the shifter’s axis, is closest to a prolate spheroid.  The planar-truncation (ie sliced by two parallel planes) created the (left & right) flat faces and the knob can thus be described as a “truncated ellipsoid” or “truncated prolate spheroid” but anyone wishing to out-nerd the rest would probably coin something like “biaxial ellipsoid with parallel planar truncations”.

It was early in the era of second-wave feminism (1960s-1980s) that George Hurst made his brief foray into marriage guidance counselling.  First-wave feminism (1895-1950s) is sometimes called the “de jure” or “structural” period because the focus was on legal issues such as women's suffrage, property rights and political candidacy but, in the West, an early victory was overcoming any opposition to women being granted driver’s licences.  Attitudes however evolved not wholly in parallel with legal rights and even today, among some, the view persists it’s men who are focused on performance and speed while women value vehicles using other criteria.  Impressionistically, that stereotype is not wholly without foundation but, since second wave feminism reset the rules, it’s no longer possible to run advertising perpetuating the notion.  The “His and Hers” shifter worked with a key-lock which enabled the husband to ensure only he could use the “manual override” feature and the idea in recent decades has been revived although this time the target of the lockout includes one’s (presumably male) children and any concierge or attendant who might be entrusted with parking one’s car.

The magic of Hurst’s shifters was in the mechanism but, just as for computer users the mouse and keyboard assume great importance because it’s by touching these relatively simple pieces of hardware that use can be made of the machine’s more sophisticated internals, it was the shifter’s knob which was a driver’s most intimate connection with the transmission.  Although in the art deco era there had been some lovely detailing, it wasn’t until the 1960s most conceptually moved beyond beyond “variations on a theme of sphere” and Hurst was among the manufacturers to explore shapes and substances.  There were “T-Handles” (which, usually as "T-Bars", were for decades popular around the world for automatics) and “Horseshoes” which attracted admiring glances but didn’t catch on and any number of novelty items including billiard balls (the “8 ball” predictably a favourite of the V8 crowd) and scale models of this and that including human body parts such as the skull and mammary gland.  Knobs could be of plastic, wood or various metals and came in designer colors, velvet coatings a nice touch of the 1960s.  The most fetishized of the muscle car era however was Hurst’s “Pistol Grip Shifter” which did what it said on the tin: it gave the user the feeling of holding a handgun.  In the 1960s, gun culture in the US hadn’t yet become what it is today (as now defined, the first “mass-shooting” didn’t happen until 1966) but it was still a place with a lot of firearms.  However, despite the potential implications, when in 1970 Chrysler made one standard equipment on the 1970 Plymouth ‘Cuda, one brochure made mention of the device only with the bland: “...a convenient pistol grip”.  For a corporation which called the Cuda’s hood scoop the I.Q.E.C.A.G. (Incredible Quivering Exposed Cold Air Grabber), it seemed a missed opportunity though it didn’t have much linguistic luck with I.Q.E.C.A.G., customers and everybody else deciding it was a “shaker”.

Architecturally, the choice between specifying door levers or door knobs is often one of mere preference or aesthetic conformity but for public or commercial buildings, some regulatory authorities now mandate the use of levers because typically they are easier to use for those with disabilities (especially if hand-mobility is limited) as they demand less dexterity.  Additionally, being circular and often highly polished, knobs can be hard to use with wet hands so that’s a consideration in kitchens, bathrooms and such; nor do young children find them as convenient as a handle.  So, all that would seem to make a compelling case for the handle but for domestic use, there’s one quirky consideration some may wish to include when making the choice.  While there are verified cases of cats and dogs learning to open doors using a handle, no pet has yet been observed mastering the turning of a door knob; while a rare problem, the chance of one’s cat or dog opening door using a lever is not zero and, because houses tend to use the same style of lever throughout, once they have learned to open one door, they’ve really learned to open all.  If it’s a concern, the good news is most doors are adaptable for either so replacing a lever with a knob does not usually require the door being replaced.
