Breakdown

Breakdown (pronounced breyk-doun)

(1) Of machines, a breaking down, wearing out, or sudden loss of ability to function efficiently; something, typically a vehicle or other machine that has experienced mechanical failure.

(2) In political science (of societies), economic collapse, societal fracturing etc.

(3) In mental or physical health, a form of collapse (figurative & literal), associated typically (1) with a sudden worsening of physical health (although that may be the culmination of long-existing issues) or (more commonly) mental stability, resulting in an inability to carry on normal activities; an instance of these manifestations.

(4) In relationships (personal or institutional), a fracturing of previous feelings or arrangements between parties; a failure of or within a relationship; often as a prelude to a “break-up”; a failure or loss of organization in a system.

(5) An analysis or classification of something; division into parts, categories, processes etc; a separation of a thing into components; decomposition, fragmentation.

(6) The detailed categorization, itemization or listing of the components of a thing (usually in printed or digital form).

(7) In biology & chemistry, the natural process of decomposition; specifically in chemistry, the breaking of chemical bonds within a compound to produce simpler compounds or elements; an instance of this.

(8) In physics, the sudden (sometimes damaging) transition of an electrical insulator to a conductor when subjected to a sufficiently strong voltage, caused by the partial or complete ionization of the insulator; an instance of this; also, the minimum voltage at which this occurs.  The classic example is an electric discharge passing through faulty insulation or other material used to separate circuits or passing between electrodes in a vacuum or gas-filled tube.

(9) In bodybuilding, gym routines etc, the “drop set” (a weight training technique).

(10) In veterinary use (equine medicine), injury to a horse's leg causing lameness; an instance of this.

(11) In rugby union, the short period of open play immediately after a tackle and before and during the ensuing ruck (and, to some extent, the maul). 

(12) In film, television (and such) production, a detailed description of a forthcoming project or screenplay which identifies all the required elements, such as the cast, costumes, equipment, props, special effects etc (separate from financing aspects likely also to involve multiple breakdowns, often on spreadsheets).

(13) In forestry, an act of splitting logs of wood using a large saw in a sawmill; the saw used or (rarely) the building in which the process is carried out (use of the term uncommon outside New Zealand.

(14) In music, a part of a piece of a composition that differs from other parts in that it features improvisation or is stripped down (played using fewer instruments or performed by a soloist).

(15) In music, a synonym of “percussion break” (a percussion-focused segment of a song, interpolated through cutting, mixing, and other techniques in order to create “rhythmic music”).

(16) In music, (especially the ominous-sounding sub-genres metalcore, grindcore, & deathcore (the distinction best explained by experts)), a section of a song, characterized by a lower tempo, greater “heaviness” and intensity of sound.

(17) In music, a loud, lively dance from folk traditions, historically conducted usually in a rural setting, most prevalent in the US, south of the Mason-Dixon Line; the terms  “hoedown” & “shindig” are related; a piece of music played for such an event, historically especially the rapid bluegrass tunes featuring the five-string banjo.

1832: The construct was break + down.  Break was From the Middle English breken, from the Old English brecan (to divide solid matter violently into parts or fragments; to injure, violate (a promise, undertaking etc.), destroy, curtail; to break into, rush into; to burst forth, spring out; to subdue, tame (the past tense of bræc & past participle of brocen), from the Proto-West Germanic brekan, from the Proto-Germanic brekanan (source also of the Old Frisian breka, the Dutch breken, the Old High German brehhan, the German brechen and the Gothic brikan), from the primitive Indo-European root bhreg- (to break).  There evolved strong linguistic links with brick, brake & breach.  The thirteen century past tense “brake” became archaic but the past participle “broken” endured, the shortened form “broke” in use by at least the mid 1300s and said by the OED (Oxford English Dictionary) to be “exceedingly common” during the eighteenth & nineteenth centuries.  The alternative form is the hyphenated break-down and in scientific use the two spellings can be applied for different purposes.  Breakdown is a noun; the noun plural is breakdowns.

Poster for Women on the Verge of a Nervous Breakdown (1989).

The early nineteenth century use was in the sense of “a collapse, a falling apart”, and was of machinery or mechanical processes; the use in metal health (as “nervous breakdown”) documented in the medical literature since 1866 but clinical or oral use may have a longer history.  As a transitive verb, the phrase “break down” was in use by at least the late fourteenth century (in the sense “take down by breaking” while as an intransitive verb (“come down by breaking”), use seems to have emerged in the late 1820s.  As early as 1856 the use is attested in the sense of “to fail through incapacity, excess emotion etc” and this presumably influence the adoption a decade later in the context of discussing mental health (it was in the mid nineteenth century something recognizable as “psychiatry” (in the modern understanding) began to evolve.  The noun (specifically of machinery) was in use by at least 1838 while the meaning “an analysis in detail” emerged in US management jargon in the mid 1930s, based on the notion of “breaking a process into its component parts to permit better analysis of both the pieces and the whole” (an extension of the verbal phrase in use earlier in the decade in the sense of “analyze, classify”.  The American folk dance tradition of “a noisy, lively dance sometimes accompanied by singing” was documented by 1864 but historians suggest the musical form dated back decades and was recorded in writing only when witnesses from the North were documenting conditions in the South towards the end of the US Civil War (1861-1865).  Breakdown became a common element in formation (breakdown crane, breakdown lane, breakdown lorry, breakdown truck, breakdown point, breakdown voltage, climate breakdown, electrical breakdown, mental breakdown, nervous breakdown, organizational breakdown, structural breakdown, supply-chain breakdown etc.

World Rugby's Laws of Rugby Union (2026 edition).  Although the word “breakdown” is not used, the rules (14, 15 & 16) regulating the well-known concept are detailed on pages 68-80.

Because just about any object could be broken, “break” widely was adapted, even serving (of paper & fabric) a la the later senses of “cut”, “tear” or “divide” although in Old English the sense of a broken bone was always “brecan”.  The intransitive sense of “be or become separated into fragments or parts under action of some force” dates from the late twelfth century, extending within decades to “make a first and partial disclosure” while the idea of “lessen, impair” was current by the late 1400s.  The sense of in some way to “destroy continuity or completeness” was from at least the 1740s while in 1882 the phrase “to break” is recorded in reference to physical currency (ie convert large denomination banknotes or coins into smaller units of the same total value).  Although in principle rugby union remains a simple game (once with a four-page rule book), under the auspices of the wise men of the IRB (International Rugby Board, 1886-2014) and later the equally diligent men & women of World Rugby (since 2014), the core rule book is now a hefty 100-odd pages so while it remains simple (relatively speaking; it’s a game of “shapes” rather than “angles”) to play, it’s quite a challenge for referees and as an example, during a breakdown, one referee might find a half-dozen transgressions to penalize while another would “allow the game to flow”, the latter approach preferred by most spectators.  In those hundred pages, the word “breakdown” doesn’t appear but that aspect of the game is covered by rules 14 (Tackle), 15 (Ruck) & 16 (Maul).

The figurative sense of “breaking someone’s heart” (although in modern medicine it’s now acknowledged people can “die from (figuratively) broken heart”) was in use by the late 1300s and other such adaptations included “break bread together” (share food) (late 1300s); “break ground" (to dig or plough land for agricultural purposes) (1670s and by 1710 that literal use was extended figuratively to mean “begin to execute a plan”)."  To break the ice as to “overcome the feeling of restraint in a new acquaintanceship” and was from the late 1500s, the reference being to the “coldness" of encounters of strangers.  The familiar break wind (the sanitized form of “a fart”) was documented in the 1550s but, farts being more ancient, use could have predated that.  The also familiar “to break (something) out” could come from anywhere but was recorded in the 1890s as dock-worker’s slang describing freeing cargo prior to unloading.  The ironic theatrical good luck incantation “break a leg” was definitely in use early in the twentieth century and similar forms exist also in Italian & German.  According to some sources, in the seventeenth century it was used euphemistically (of a woman) to convey “to have a bastard child.”

Cup of char.  Under the Raj, the ritual of the "tea break" in the Indian Civil Service became codified (time span; size of cup according to the official's grade of employment).

The thirteenth century noun use (act of breaking, forcible disruption or separation) came from the verb but apparently not until the late 1500s was it customary to speak of “daybreak” or “break of day” but that notion was by the 1720s in use with the meaning “a sudden, marked transition from one course, place, or state to another”.  The first meal of the day (ie when one “breaks one’s overnight fasting)” was by the mid fifteenth century routinely called “breakfast”.  The sense of a “short interval between spells of work” began in schools in the 1860s and the concept came widely to be applied (sport, employment etc) and was sometimes codified in rigid forms (by the Indian Civil Service’s “tea break” in 1911 and the BBC (British Broadcasting Corporation) in broadcasting in 1940).  The meaning “stroke of luck” (widely used: “lucky break” or “give me a break”, “never give a sucker an even break” etc) is believed derived from billiards (a game in which the “opening break” (first shot) scatters the ordered balls and is attested from 1865).  The use in music began in the 1920s when jazz musicians began to refer to “improvised passages or solos” thus, the idea being something that was a “break” between structured sections.  The original dance form called “breakdown” (defined by the OED as “a riotous dance, in the style of the negroes”) was probably from some time in the nineteenth century but definitely was from south of the Mason-Dixon Line although element of the style probably can be identified in the folk traditions of many cultures.

Raygun Breaking.

Australian breakdancer (breaker) Dr Rachael “Raygun” Gunn (b 1987), during her much-discussed “highly original” performance at the 2024 Paris Summer Olympics.  Between 2020-2026, Dr Gunn was a lecturer in the Department of Media, Communications, Creative Arts, Language & Literature at Macquarie University Faculty of Arts, Sydney, Australia.  Her Ph.D thesis (2017) was titled Deterritorializing Gender in Sydney's Breakdancing Scene: A B-girl's Experience of B-boying in which she explored “The intersection of gender and Sydney's breaking culture”.  The Ph.D was in the (obviously wide) field “cultural studies” but after her appearance in Paris was publicized, on X (formerly known as Twitter) there was much comment about universities conferring “doctorates in break dancing” being a sign of decline in academic standards.   

The more modern “breakdance” seems to have begun in New York City in the 1970s; it was when DJs (disc jockey) played exclusively the “rhythmic break sections from pop-dance songs” and crowds danced accordingly, originally presumably impromptu but the discipline later evolved into choreographed structures.  If, upon entering a room, one sees breakdancing in progress, one’s comment to one’s companion should be: “We are among barbarians.”  Break dancing was included as a “sport” in the 2024 Olympic Games in Paris although the participants are said to prefer it be called “breaking” and the appearance in Paris is thought to have been an attempt to seek the younger demographic not attracted by the charms of “Olympic traditions” such as Greco-Roman wrestling.  The reaction was mixed and, at this time, Breaking is not on the schedules of either the 2028 (Los Angeles) or 2032 (Brisbane) games.   

Although “down” can be used also as a noun, verb, adjective & preposition, as an element in the noun “breakdown”, it operates as an adverbial particle.  What it does is modify the meaning of the verb “break” (in this sense “indicating separation or failure” to create the new noun.  In this context (in a descending direction, from a higher to a lower place, degree, or condition), the pre 1000 down was from the Middle English doun & doune (down), from the Old English dūne (down), an aphetic (loss of a word's initial unstressed vowel) form of adūne (down, downward), from the earlier ofdūne (down (literally “off the hill”), the construct being of- (of, off) + -dūn(e) (hill, mount, dune, down).  Influencing the development from directional phrases to prepositions were the Old Frisian adverb dene (down (literally “(to the) floor”)), the Middle Low German dāle (down, downwards (literally “(in/to the) dale/valley”) from which the German Low German gained dal (down).  The form was cognate with the Scots doon (down) and can be compared with the Saterland Frisian deel (down (literally “to/into the dale”)) and the West Frisian del (down).  The familiar meaning “in a descending direction, from a higher to a lower place, degree, or condition” was inherited from a late development in the Old English that produced a shortened form of the earlier ofdune.  While in general Germanic, this sense development of “hill" uniquely was English.  As a preposition used to mean “in a descending direction upon or along”, use dates from at least the late fourteenth century.  As an idiomatic form, the uses in English of “down” (both literal and figurative) are legion.

Satirical engraving LADIES! LADIES! Mystery of Modern Modesty, Fun magazine, 12 March, 1870.  At the time there was a national debate about the operation of the Matrimonial Causes Act (1857) and the Women's Property Act (1870).

The 1857 Act created a Court of Divorce and Matrimonial Causes and it was in many ways an advance in women’s rights in that it made divorce more accessible but there was an inherent unfairness (something perhaps not surprising in a law emerging from an all-male parliament).  While, as before, men could divorce their wives on the basis of adultery alone, a woman was compelled to prove not only her husband’s adultery but also an additional cause (one or more of cruelty, desertion, incest, rape, sodomy or bestiality).  It was a sexual double standard, the origins of which can be traced to Biblical scripture and reinforced in law the notion a woman's infidelity was inherently worse than that of a man.  Despite that hurdle, the acts did make things slightly better for women in that for the first time there was statutory protection ensuring a divorced woman’s future earnings and property were shielded from claims by an ex-spouse.  Gradually, other reforms further improved things but what didn’t change until the “no fault” principle to some degree civilized divorce proceedings was that the act made “break-ups after break-downs” into a spectator sport and there were tabloid newspapers with sometimes pages of coverage of the antics of the famous or the more salacious conduct by others.

Breakdownism is legal slang referencing the “no-fault” principle existing in many jurisdictions as grounds for divorce.  First becoming popular during the 1970s, it essentially created “divorce on demand”, a reform that has had far-reaching effects (both good and ill) and is thus far thought the “final state” of Western divorce law; certainly it’s an advance “contested” divorces (often highly entertaining matters for others than the parties whose infidelities were being publicized, sometimes with appropriate photographic evidence.  The classic “contested divorce” was a creature of the old Matrimonial Causes Act (1857); prior to that a “complete divorce” permitting remarriage almost always required a private Act of Parliament, a procedure expensive and highly public.  It was also time-consuming, demanding (1) proceedings in an ecclesiastical court seeking an order of separation, (2) in the case of a husband seeking divorce, a successful action for “criminal conversation” (damages against the adulterer) in a common-law court, (3) a correctly drafted private divorce bill introduced into the House of Commons (“first reading”), (4) debate(s) on the bill (“second reading”) that might see the matter (5) “referred to committee for consideration”, (5) a vote in on the bill (“third reading”) that, if passed would see the bill (proposed law) sent to “the other place” (House of Lords) for (6) three readings, possible committee stages and a vote.  If the bill survived all that, it became an act and upon (7) royal assent being granted (by a monarch or their representative (governor, governor-general etc) it was valid law and the divorce had happened.  The subsequent (8) “gazetting” (publication in the Government Gazette) was merely procedural.

So one really had to want a divorce and have the means to obtain one; given all that, it’s not surprising wives and husbands were sometimes murdered as a “work-around”.  One handy solution was however available to certain colonial administrators resident in places where the Islamic Sharia courts operated, applicants often finding the judges much more sympathetic to men wishing quickly to rid themselves of now unsatisfactory wives.  The concept of “breakdownism” ended most of the legal entertainment and the notion of “irreconcilable differences” became the standard expression cited as grounds for divorce.  Regrettably, the tale of one eighteenth century bishop “bribing or persuading" a parliamentary draftsman to insert in an innocuous (and thus not diligently scrutinized) bill the line: “the Bishop of xxx is declared divorced” appears to be apocryphal and may have begun as an illustrative example of the supremacy of parliament over sovereign & church before becoming a “legal legend”.  It probably is a good thing members of the House of Lords no longer debate whether or not to grant someone a divorce because that would at times have meant Lord Peter “Mandy” Mandelson (b 1953) having a vote and the thought of him opining on matters of the conduct and personal morality of others is something to ponder.  The term “meltdownism” is non-standard and used of those for whom “having meltdowns” seems a calling or who obviously “stage” them as a tactic.

Barnes Auto advertising, circa 1939.

In business before World War I (1914-1918) Barnes Auto operates a towing business in Brisbane, Australia, their trucks still adorned in striking blue and orange stripes.  Around 1937, the decision was taken to build a “streamlined breakdown lorry” and while designers in Europe and the US had for some years been applying aerodynamic techniques to heavy trucks, most were produced to improve average speeds and lower fuel consumption on (relatively) high-speed, long-distance routes.  Influenced by advances in aviation, streamlining since the 1920s increasingly had appeared on vehicles on both sides of the Atlantic, the best remembered the grand prix and LSR (land-speed record) machines but stylists (with and without wind-tunnel data), applied the techniques both to mass-market and expensive vehicles so trucks were a logical subject for study given the importance to operators of time and running costs.  Whether Barnes Auto’s 78 HP (horsepower) breakdown lorry, geared as it was to suit its purpose, would often have attained speeds at which the presumed aerodynamic advantages would have rendered either better performance or economy is dubious and the shape may have been more an art deco inspired “rolling advertisement” rather than a piece of functionalism but, if that was the case, it worked because it appears to be the only Brisbane “tow truck” of the era to have survived as a feature in the photographic record.  Certainly, compared with other trucks at the time on the road, the blue & orange striped machine must have been eye-catching.

Barnes' Breakdown Lorry fully loaded, three behind, one in front.

Lorry is of uncertain origin but thought most likely from the dialectal English lurry (to lug or pull about, to drag).  The use emerged in the early to mid-nineteenth century and was applied initially small carts or wagons (both hand propelled and horse-drawn), use quickly extending to the open carriages used on railroads to haul goods or commodities.  In much of the English-speaking world, from the early twentieth century, use transferred to motorized vehicles used for the same purpose and that made sense because the earliest powered lorries literally were the same “carriages” with an engine and drive-train added.  “Lorry” in that sense endures in some places in the old British Empire (notably in India & Pakistan where the linguistic inheritance of the Raj remains strong) but in many places (certainly North America), “truck” (and other specialized forms) became preferred.  Even in some places where use of “lorry” lingers, it's now often a sometimes rare niche word describing freight-vehicles larger than “pick-ups” but smaller than “trucks”.  In Australia and New Zealand, it's possible “lorry” may go extinct as those who grew up with the word age and die.

“Tugboat Annie”, waiting for a breakdown needing a tow, Mankato, Minnesota, US, 1937.

The coach-built body was created by (the still operating) Watt Brothers of Wolloongabba on a 1938 Dodge two-ton truck chassis, shortened, reinforced and converted to full forward control.  Although new to Brisbane, similar lines had been seen in US, notably on “Tugboat Annie”, built in Mankato, Minnesota and based on a 1937 International cabover tow truck; presumably such things provided the template followed by the Watts.  The 78 HP, six cylinder engine (one of the variants of Chrysler’s long-serving “flathead six, 1924-1963), was connected through a series of reduction gears via a double-faced clutch to a double jib hoist capable of a ten-ton lift with the lifting and trailing gear arranged so four vehicles simultaneously could be towed: three at the rear, one in front, an apparatus now unlikely much to impress Australian regulatory.  There doesn’t appear to be footage of the breakdown lorry on the move with four broken–down cars attached (three to the rear, one in front) but it would have required a driver with skill and experience, especially to handle the behaviour of the one ahead, the whole ensemble presumably acting like something centrally “hinged”.  On aspect that would have assisted in that was the outstanding visibility the styling afforded a driver, the extremities of the load being a critical thing to monitor.  Because of the four-vehicle capacity, an impressive 600 feet (183 metres) of wire rope was carried, the location of the connection-points on the towed vehicles an important factor in maintaining directional control while in movement.  The Breakdown Lorry served throughout World War II (1939-1945) and wasn’t replaced (by a conventionally styled, English-built, crew cab Dodge) until the mid 1950s.  Regrettably, Barnes proved unsentimental about retired equipment and once deemed obsolete, Breakdown Lorry was sent to a local rubbish dump, meaning an improbable piece of art deco history was lost but, because of the evidence in photographic archives, the distinctive lines attracted the model-makers, Autocult releasing one in 1:43 scale.

The Breakdown Lorry with Douglas DC-3, Brisbane International Airport, circa 1942 (colorized image).

In Australia, the DC-3 was operated by the RAAF (Royal Australian Air Force), Ansett Airlines, TAA (Trans Australia Airlines, ANA (Australian National Airways) and a myriad of smaller operators.  Produced mostly between 1936-1945, over 600 were built; robust, economical to operate and with an admirable safety record, it was for years a mainstay of civil aviation and General Dwight Eisenhower (1890-1969; POTUS 1953-1961), who often travelled in one while Supreme Commander Allied Expeditionary Forces (1943-1945), reckoned the DC-3 was one of the tools (others including the bazooka and Jeep) that made Allied victory in World War II possible by 1945.  The DC-3 in the photograph is "Kyilla" (registered as VH-UZJ), the first one imported into Australia (the invoiced cost Aus£41,000).  Delivered in November 1937, it flew with AoA (Airlines of Australia, an operator that in 1931 originally traded as NEA (New England Airlines) before in 1942 being absorbed by ANA).  Between 1939-1940, Kyilla was leased (“temporarily impressed” the wartime terminology) to the RAAF to cover a “delivery gap” and in 1943 it commenced regular service in ANA.

Autocult's 1:43 scale model.

Trucks in the era were anyway low-geared (in some jurisdictions, above a certain gross weight, maximum speeds as low as 30-40 mph (50-70 km/h) sometimes were imposed but the gearbox in the Barnes Breakdown Lorry had an unusually low ratio first-gear (a so-called “stump puller” of the type often seen in agricultural vehicles), enabling it to ascend even the steepest grades, allowing vehicles to be recovered from hilly terrain.  The apparatus used for the double jib hoist must have been intriguing to see and the mechanism, developed in-house by Barns was fine piece of engineering, combining intricacy with robustness while eschewing needless complexity.  In that it followed the maxim on design and problem-solving coined by German architect Professor Heinrich Tessenow (1876-1950): “The simplest form is not always the best, but the best is always simple.”  That was a refinement of novacula Occami (Occam's razor), a principle attributed to the English Franciscan friar, theologian & philosopher Guillelmus de Ockham (William of Ockham circa  1287–1347).  Occam’s razor (the idea one of “cutting away the unnecessary”) recommends searching for explanations constructed with the smallest possible set of elements; on that basis it was styled also as lex parsimoniae (law of parsimony), often glossed as Entia non sunt multiplicanda praeter necessitate (Entities must not be multiplied beyond necessity).  Even today the mechanism on a tow truck is a fine example of Professor Tessnow’s maxim being applied with brutish efficiency although modern regulations mean something as intriguing as Barnes’ “four strand” arrangement can no longer be used.

One of the many curiosities in English is despite “up” & “down” being diametric opposites, “break down” and “break up” can mean the same thing.  In human relationships, it’s not uncommon for a “break-up” of a couple to follow a “break-down” in their relationship but when applied to physical objects, some are said to be “broken down” while others are “broken up”, despite the processes being conceptually much the same.  The apparent anomaly is explained by the history of the industries involved and conventions of English.  As a general principle, of objects, “break down” means “to dismantle something into its constituent parts or to reduce it to a simpler state”, meaning the term is used to emphasize fragmentation, destroying the integrity of something as a single object.  Despite that, the convention in the business of “shipbreaking” (literally “cutting apart” vessels and using the metal as “scrap”) is of being “broken up”.  The origin of shipbreaking dates from the nineteenth century when the iron and later steel that had come to be used for the structures was valued as scrap metal after a vessel’s economic life had ended.  This involved sometimes dozens of workers stripping fittings from hulls before progressively cutting or demolishing what remained, section by section, until nothing recognizably nautical remained.  In the industry and in news reports, even then the process routinely was referred to as “breaking up”. 

Putting up a final struggle: HMS Vanguard aground on the way to the wrecker's yard to be broken up, Portsmouth Harbour, England, 4 August, 1960.

Launched in 1946, Vanguard was the RN's (Royal Navy) last dreadnought and no nation has since commissioned a battleship.  In the space of a half-century, the battleship shifted from the most powerful military weapon on earth to a white elephant and despite use of the word “battleship” during Donald Trump's (b 1946; POTUS 2017-2021 and since 2025) recent mention that the USS Defiant would be the first of the new “Trump Class” of surface warships, the USN (US Navy) will not be launching any true “battleships”, the service having in 1992 struck from the list the last of the four Iowa Class ships commissioned between 1943-1944.

Obviously, shipbreaking, while in a sense a well-planned and careful “disassembly”, was an act of “total and final destruction”, the many pieces of metal sent to be “melted down” before being transformed into something else (not necessarily another ship).  That use of the term was different from the process undertaken by mechanics or technicians when “breaking down” a piece of equipment. Something done typically to effect repairs or maintenance, the emphasis very much on a carefully ordered process, disassembly most systematic because all or some of the components removed would need to be restored to their original positions when the thing was “put back together”.  So that’s how the conventions emerged: (1) “breaking up” a destructive process and (2) “breaking down a step in processes of repair, maintenance or upgrades.  Deconstructing the elements at the etymological level, there’s no reason why the terms couldn’t have been applied the other way round but, by patterns of use, the idiomatic forms became fixed.

A Lindsay Lohan “meltdown scene”, The Canyons (2013).

In the furnaces fed by the shipbreakers, to “melt down” was literally to bring scrap metal to its melting point, meaning it flowed like a liquid and could be cooled to form into shapes able to be re-used (plates, bars, beams etc).  In the post-war years, “meltdown” (first in this context recorded in 1963) ominously became familiar as the graphical encapsulation of what would happen to at least a large part of the core of a nuclear-reactor were the fuel elements subject to inadequate cooling.  The idea was the highly radioactive core would become so hot it would “melt down”, through the floor to the earth below.  Depending on the thickness of the facility’s concrete floor a core could in theory do exactly that but extending the idea to the popular description “China syndrome” was fanciful.  That idiom was based on the notion that if one (in Europe) kept digging a hole, eventually they’d dig “all the way to China” (“China” a synecdoche for “other side of the world”).  In many places the geography would have been dubious but so too the geology; even by 2026 the deepest hole ever dug remains Hole SG-3 (Kola Superdeep Borehole) in Russia’s Murmansk region.  Begun as a Soviet scientific project in 1970, by 1989 it achieved a vertical depth of 12.7 kilometres (7.6 miles) into the Earth's continental crust at which point the project had to be abandoned because temperatures at the drill bit had reached 180°C (356°F), much hotter than the expected 100°C (356°F).  At that level, rock becomes too soft successfully to drill.  Technically, the 12.7 km depth was a remarkable piece of applied engineering but to put the “China Syndrome” into perspective that’s around 0.2% of the way to the planet’s centre (the Earth's radius is some 6,371 kilometres (3959 miles)).

The “Elephant's Foot”, Chernobyl Nuclear Power Plant, Ukraine.  It came more to resemble a boot but when first identified, it was though to be more “pachydermish”.

So, in a nuclear meltdown, a core would have a long way to go and, in the most infamous example to date, the core didn’t get even to the Earth’s surface.  In April 1986, reactor 4 of the Chernobyl Nuclear Power Plant (in Ukraine, then one of the constituent SSRs (Soviet Socialist Republic) of the Soviet Union (1922-1991)) exploded after a serious of procedural errors in what was, with the darkest irony, supposed to be a routine “safety test”.  When the heat of the core passed the “critical point of no return” the meltdown started, the core (a molten, toxic, lava-like mixture of uranium fuel, graphite, steel and concrete (“corium” in the jargon) melted through the bottom of the reactor vessel, flowing through pipes, corridors, and steam suppression pools inside the building.  The core did however stay completely within the facility’s basement levels (made from thick concrete) and it remains radioactive although it has now cooled to the point where it’s possible to stand relatively close without receiving a dangerous dose although, uranium being almost inert, if left undisturbed, when (10 billion years from now) our Sun expires (having “burned up” the fuel sustaining its nuclear fusion) some 25% of it will remain extant and the Elephant's Foot will be about as radioactive as its weight in bananas.  A banana contains Potassium-40 and is about as radioactive as a typical carrot or potato but other foods are more so, Brazil nuts by a factor of more than three.

In informal use, “meltdown” is used of sudden declines in stock prices or other undesirable “sharp market corrections” but the most popular use is of “dramatic performances” (of grief, rage, despair etc) consequent upon a sudden loss of control over one’s feelings or behavior.  Mothers will be familiar with meltdowns by their toddlers, typically over life-changing issues such as not getting an ice cream or the television being switched-off.  On screen, one of the most famous depictions of a meltdown was the performance of Swiss actor Bruno Ganz (1941-2019) as Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) in Downfall (2004), a study of the characters in the Führerbunker during the “last days of the Third Reich”.  The performance inspired an entire genre of “Hitler Rant Parodies”, the quality of which is “patchy”.  Hitler’s meltdown came during a military briefing after learning Waffen-SS (Armed SS) Obergruppenführer (general) Felix Steiner (1896–1966) had failed to assemble the forces to launch a relieving attack Hitler had ordered against the Red Army formations besieging Berlin.  That was by then militarily impossible but the unwelcome news induced in Hitler a legendary rant of several minutes during which he ranged against those he thought responsible for his predicament, notably the army’s officer corps and even the previously trusted SS.

The SS (ᛋᛋ in Armanen runes; Schutzstaffel (literally “protection squadron” but translated variously as “protection squad”, “security section" etc) was formed (under different names) in 1923 as a Nazi party squad to provide security at public meetings (then often rowdy and violet affairs) and was later re-purposed as a personal bodyguard for Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945).  The SS name was adopted in 1925 and during the Third Reich the institution evolved into a vast economic, industrial and military apparatus more than two million strong to the point where some historians (and contemporaries) regarded it as a kind of “state within a state”.  The Waffen-SS (armed SS (ie equipped with military-grade weapons)) existed on a small scale as early as 1933 before Hitler’s agreement was secured to create a formation at divisional strength and growth was gradual even after the outbreak of hostilities in 1939 and it was the invasion of the Soviet Union in 1941 which triggered the Waffen-SS’s expansion into a multi-national armoured force with over 900,000 men under arms.  As well as the SS’s role in the administration of the many concentration and extermination camps, the Waffen-SS was widely implicated in war crimes and crimes against humanity.  Towards the end of the meltdown, Hitler, with tears in his eyes, admitted the war was “lost”, something that was by then (or should have been) obvious to all in the bunker.  Although only two of those who witnessed the meltdown survived the war to tell the tale (Generaloberst (Colonel General) Alfred Jodl (1890–1946, chief of the OKW operations staff 1939-1945 and Generalfeldmarschall Wilhelm Keitel (1882–1946; chief of OKW 1938-1945)), such was the volume it was heard by many in an adjoining room and historians agree Ganz’s performance captured the moment.

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.

Although a sight to delight button-nerds, "peak button" unfortunately coincided with the "biodegradable wiring incident" (1991-1995) in which the soy-based insulation for the cables deteriorated some decades before the supplier's projected end-of-life, the issue exacerbated by the taste of soy which would attract rodents and other creatures happy to chew on the stuff for a quick snack.  The basic shape of the gear selector knob dates from one introduced in 1971 in the 350 SL (R107, 1971-1989), the design a product of analysing data from the Swedish government's mandatory post mortems (autopsies) of road-accident fatalities (under Swedish law, such corpses were for 48 hours the property of the state).  What the pathologists' findings revealed was lives could be saved if engineers could devise as a shift lever handle too large to penetrate the eye socket.  While there's an element of the macabre in such research and it wasn't something the factory choose widely to publicize, the design was a classic example of what's called "passive safety".

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”.

Close-up of balsa wood gear-shift knob in Porsche 917K.

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.

2006 Spyker C8 Laviolette Widebody: Dashboard layout with four-spoke “propeller” steering wheel (left) and toggle switches with nerf-bars (right).  While screens may for certain purposes be better than knobs & switches, the latter often are easier to use and visually, can be most pleasing.

What Porsche did in designing the linkages to the transaxle was dictated by nothing other than usual the design imperatives for racing cars: robustness, reliability, ease of operation and lightness, the use of balsawood as an “anti heat-soak” material wholly in accord and the same parameters were applied by Spyker when designing their distinctive shift mechanism.  Spyker, a boutique operation from the Netherlands, began operation in 1999, the name coming from a Dutch coach-builder that between 1880-1926 would branch out from horse-drawn carriages to automobiles and even aircraft.  Since 2000, between various local difficulties (including bouts of bankruptcy), Spyker has produced a number of high-performance models and while the mechanical specification has always been impressive, what has also drawn attention are the exquisitely finished interiors, the attention to detail (typified by the nerf-bars used to make lawful the use of toggle switches) a delight for those who study such things.  Unfortunately the four-spoke “propeller” steering wheel (a style last seen in volume on the Jaguar XK150 (1957-1961) was eventually judged just too potentially lethal to be granted an exemption from compliance and was replaced with something more accommodating from the Lamborghini parts-bin.

While Spyker’s wonderfully crafted shift mechanism for the rear-mounted ZF transaxle with exposed shafts of stainless steel might seem an affectation, it’s pure functionalism; being a direct mechanical linkage, they provide precise gear-shifting, always a challenge with such a layout (the Porsche 914 (1969-1976) community coined “broomstick in a jar of mayonnaise” to describe the to describe the experience of the earlier "tail-shift" models, the post 1972 "side-shift" build a great improvement from "bad" the "satisfactory").  Spyker’s engineering is thorough and although pure-steel from transaxle to knob, heat-soak along the shaft is said to be minor so there was no need to resort to timber for the knob.

1959 Ford Fairlane Galaxie 500 Sunliner with suicide knob (on steering wheel at 10 o'clock).  This was a generation before "softer, gentler steering wheels".

“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 Nader (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 toll 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 knob for the two-speed Powerglide automatic transmission in 1953 Chevrolet Corvette (left) and a classic spherical shift knob in 1972 Chevrolet Corvette LT1 (available only with a 4-speed manual transmission).  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 for the handful of 1964 300Ks fitted with a manual transmission.  One amusing geometric quirk is the three-dimensional sphere and two dimensional circle share the same definition: A shape in which all points are equally distant from the centre. 

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.

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.
