Pre 900: From the Middle English wegge, from the Old English wecg (a wedge), from the Proto-Germanic wagjaz (source also of the Old Norse veggr, the Middle Dutch wegge, the Dutch wig, the Old High German weggi (wedge) and the dialectal German Weck (a wedge-shaped bread roll) and related to the Old Saxon weggi.  It was cognate with the dialectal German weck derived from the Old High German wecki and Old Norse veggr (wall).  The Proto-Germanic wagjaz is of uncertain origin but may be related to the Latin vomer (plowshare).

From the early fifteenth century, the verb form emerged in the sense of "jam in place with a wedge; tighten with a wedge", the figurative sense "drive or pack (into)" dating from 1720.  The meaning "split (something) apart with a wedge" is attested from 1853.  The general use to describe things shaped like a wedge began in the 1610s and use of the phrase "thin edge of the wedge" meaning a minor change that leads to a major change, especially one thought undesirable, dates from the mid nineteenth century.  Although the style had been produced earlier, the type of women’s shoe called “wedge” was advertised in 1939, a spike in the popularity of the style in the early 1970s cause a brief, world-wide shortage of cork because demand suddenly exceeded the supply which relied substantially on the Portuguese crop.

Wedge Politics

Wedge politics is the art of identifying an issue of importance to one’s own political base but which polarises opinion in that of one’s political opponents.  A wedge issue is of a controversial or divisive nature (guns, abortion, refugees et al) which splits apart a demographic or population group which tends to be clustered in the voting base of an opposing political party.  Wedge issues can be advertised or publicly aired in an attempt to weaken the unity of a population, with the goal of enticing polarized individuals to give support to an opponent or to withdraw their support entirely out of disillusionment.

Some dictionaries cite 1999 as the origin of wedge issue as a phrase but it dates from 1990, in the run-up to that year’s mid-term US congressional elections.  A official under Jimmy Carter (b 1924; US President 1977-1981), Stuart Eizenstst (b 1943; Chief Domestic Policy Adviser and Executive Director, White House Domestic Policy Staff 1977-1981) coined the term to describe the tactics being deployed under George HW Bush (George XLI, 1924-2018; US president 1989-1993) to use affirmative action guidelines and quotas as issues “…to split the coalition of working-class whites and blacks, the two constituencies Franklin Delano Roosevelt (FDR, 1882–1945, US president 1933-1945) unified on economic grounds.  The image came to mind of a wedge being driven."  It was a refinement of what emerged during the Reagan presidency, the use of social issues to persuade the working-class to vote against their own economic interests.  In the jargon of political science, they’re also called third rail issues.  It filled a political-linguistic need for fresh labels.  As a phrase, wedge issue had a certain earthy appeal, a wedge being a familiar and vivid metaphor, more memorable than the earlier usage hot-button issue, which was too vague to summon the mental imagery and more widely used and understood than the Latinate polarization so beloved by political scientists.  Generational change means wedge issues can return to haunt the authors.  In the 1990s, gay marriage was used successfully by the Republicans to drive a wedge between the liberal and conservative wings of the Democratic Party but within a quarter-century, the universe had shifted and it was the Republicans fractured by the issue.  The hunter had been captured by the game.

The Wedge Combustion Chamber

So-named because the inside top of the cylinder head is shaped like an inclined basin, with the valves sitting at an angle so that the space between the piston and cylinder head looks like a wedge, wedge-shaped combustion chambers have been used by almost every mainstream manufacturer of internal combustion engines.  A relatively simple design, the chamber resembles an inclined basin recessed into the deck of the head, the fuel/air mix supplied (usually) by inline valves, often tilted to accommodate the sloping roof.  The spark plug tends to be located on the thick side of the wedge, positioned most often midway between the valves.

Designed to exploit the nature of fluid dynamics, the chamber’s steep walls deflect the air/fuel flow path, forcing it to move in a downward spiral around the cylinder axis.  During the compression stroke, the compressed air/fuel area reduces to such an extent that the trapped mixture is violently thrust from the thin to the thick end of the chamber, building up significant kinetic energy, which, when ignited, improves the burn rate and thus the extraction of energy: the power.  Another advantage, refined particularly from the mid 1970s, is that the wedge-shaped combustion chamber tends to have a smaller surface area than other designs and so there is less space on which droplets can condense, assisting in reducing the volume of fuel remaining unburnt after the combustion cycle, thus reducing hydrocarbon emissions.  Ultimately, the wedge-shaped combustion chamber is not as efficient or able to produce as much power as other designs but is well-suited to engines which need to deliver a compromise between torque, power and economy over a wide operating range.  It has the additional benefit of being inherently cheaper to build than others because of the simplicity of the casting and machining processes required and the structure of its valve train tends to require fewer moving parts.

Sandwedge

Sandwedge (pronounced sand-wej)

(1) As Operation Sandwedge, a proposed clandestine intelligence-gathering operation against the political enemies of US President Richard Nixon.

(2) As sand wedge, a specialized golf club, an iron with a heavy lower flange, the design of which is optimized for playing the ball out of a bunker (sand trap).

1971: The name was chosen for a “dirty tricks” covert operation as a borrowing from golf, the sand wedge a club used to play the ball from a difficult position.  The construct was sand + wedge.  Dating from pre-1000, sand was from the Middle English sand, from the Old English sand, from the Proto-West Germanic samd, from the Proto-Germanic samdaz, from the primitive Indo-European sámhdhos, from sem- (to pour).  Wedge was a pre 900 from the Middle English wegge (wedge), from the Old English wecg (a wedge), from the Proto-Germanic wagjaz (source also of the Old Norse veggr, the Middle Dutch wegge, the Dutch wig, the Old High German weggi (wedge) and the dialectal German Weck (a wedge-shaped bread roll) and related to the Old Saxon weggi.  It was cognate with the dialectal German weck derived from the Old High German wecki and Old Norse veggr (wall).  The Proto-Germanic wagjaz is of uncertain origin but may be related to the Latin vomer (plowshare).  Sandwedge is a noun; should the plural ever be needed, it would be sandwedges (ie phonetically a la the use in golf (sand wedges)).

In golf, when using a sand wedge, the player’s stance and the way in which the club addresses the ball differs from what’s done when using a conventional iron.  Noted golfer Paige Spiranac (b 1993) demonstrates the difference although there may be some variations depending on an individual's weight distribution. 

Richard Nixon.

Operation Sandwedge was a covert intelligence-gathering operation intended to be conducted against the political enemies of Richard Nixon (1913-1994; US president 1969-1974).  Beginning in 1971, the early planning was done by Nixon's Chief of Staff HR Haldeman (1926-1993), his assistant for domestic affairs, John Ehrlichman (1925-1999) and Jack Caulfield (1929–2012), then attached to Ehrlichman’s White House staff “handling special assignments” and also involved (though paid not by the White House but from external campaign funds) was Tony Ulasewicz (1918-1997), later a bit-player in the subsequent Watergate affair.  The core of Caulfield’s plan was to target the anti-Vietnam War movement and those figures in the Democratic Party Nixon had identified as the greatest threat to his re-election in 1972, including Ted Kennedy (1932–2009; US senator 1962-2009), Ed Muskie (1914–1996; US senator 1959-1980), William Proxmire (1915–2005; US Senator 1957-1989) and Birch Bayh (1928–2019; US senator 1963-1981).  Of interest too was a settling of scores with those who had prevented G Harrold Carswell (1919–1992) being confirmed by the Senate as Nixon's nominee for the Supreme Court and the president's net was internecine too, others of the targeted figures in his own Republican Party.

G Gordon Liddy.

Operation Sandwedge was intended to be clandestine but it wasn’t subtle and included physical and electronic surveillance, the intelligence of particular interest that which could be used either to feed damaging leaks to the press or for purposes of blackmail including dubious financial transactions, mental health records and sexual proclivities.  However, the operation never proceeded beyond the planning stages because Haldeman and Ehrlichman thought the methods of Caulfield (a former New York Police Officer) unsophisticated so transferred the project to G Gordon Liddy (1930–2021), a lawyer, one-time FBI agent and later one of the great characters of the Watergate affair.  Caulfield had chosen the name sandwedge because, as a dedicated golfer, he knew the sand wedge was the club of choice when one was in a difficult spot and if well-played, it was what could transform a bad situation into something good.  At the time, the code-names were probably among the more imaginative things to emerge from Pennsylvania Avenue, the name chosen for the squad to investigate leaks of information to the press was dubbed “the plumbers”.

The Watergate complex, Washington DC.

The Watergate affair was of course the most celebrated of the “dirty tricks” operations run out of (or at least connected with) the Nixon White House but it was far from unique.  Back channel operations had actually begun even before the 1968 election but by 1971 the vista had expanded to include what would now be called fake news plants, the infiltration of the staff of political opponents and break-ins and burglary, among the most infamous of which was “the plumbers” (including Liddy) breaking into the office of the psychiatrist treating Daniel Ellsberg (b 1931), the former Defence Department military analyst who had leaked the “Pentagon Papers”.  Ellsberg’s file revealed nothing of interest but the burglary gained a place in history, being recorded by Ehrlichman (who approved the operation) as "Hunt/Liddy Special Project No 1".  There would be more.

Sandwedge had been envisaged as an intelligence gathering operation, the most novel aspect of which was that while the project documents presented an overview of something using conventional methods of surveillance and the compilation of publicly available material, privately Caulfield advised illegal electronic surveillance would also be used, something any expect presumably could have deduced from the size of the requested budget.  Of the greatest interest were financial records (relating particularly to tax matters), mental health conditions, undisclosed legal problems and sexual conduct, especially if illicit and preferably unlawful.  The idea greatly interested Haldeman and Ehrlichman but they had never been convinced by Caulfield’s “lack of background” by which they meant education and political experience.  Accordingly, Sandwedge and all intelligence matters were transferred to Liddy, the article of faith in the White House being that anything run by a trained lawyer would be legally secure, not something they believed of ex-NYC policemen.

New York Times, Saturday 2 March 1974.

Liddy revelled in the role as the White House’s clandestine clearing house for “covert ops” and created his own list of spy-like code names (Gemstone, Diamond, Ruby et al) to an range of activities expanded beyond Sandwedge including physical espionage, infiltration of protest groups, secret wire-taps, sabotage of opposition campaigns and, of course, “honey-pot traps”.  Even for Haldeman and Ehrlichman the implications of becoming essentially gangsters was too much but the shell of Liddy's structure was in 1972 approved and even then it included a range of unlawful activities, including the one which would trigger the chain of events which would culminate in Nixon’s resignation of the presidency and see dozens of the conspirators (including Haldeman, Ehrlichman and Liddy) jailed: the break in and bugging of the Democratic Party offices in the Watergate complex.  As the affair unfolded, suspicion fell upon Caulfield until it was realised his role in Operation Sandwedge had ended before any dubious operations began and he’d never been part of Liddy’s more ambitious plans.  He was compelled to resign from government but was never prosecuted, maintaining to his dying day that if he’d been left to run Operation Sandwedge, there would have been no burglaries in the Watergate complex or anywhere else and thus none of the cascading scandals which at first paralysed and later ended the second term of the Nixon administration.

Slope

Slope (pronounced slohp)

(1) To have or take an inclined or oblique direction or angle considered with reference to a vertical or horizontal plane; slant.

(2) To move at an inclination; obliquely to move.

(3) To direct at a slant or inclination; incline from the horizontal or vertical.

(4) To form or describe something with a slope or slant.

(5) A descriptor of ground or some aspect of the natural or built environment which has an incline, such as a hill.

(6) An inclination or slant, especially downward or upward; to lie or cause to lie at a slanting or oblique angle.

(7) Any deviation from the horizontal or vertical; an inclined surface.

(8) In mathematics, (1) the tangent of the angle between a given straight line and the x-axis of a system of Cartesian coordinates; (2) the derivative of the function whose graph is a given curve evaluated at a designated point.

(9) In slang, a disparaging and offensive term used to refer to a person of East Asian appearance.

(10) As slope off, a slang term (mostly UK, Australia & New Zealand) describing someone moving slowly, or furtively away, usually to avoid work or responsibility; a rare variation is “sloped-in”, used to describe to who arrive somewhere surreptitiously (those late for work etc).

(11) To follow an inclined course down a hillside (applied especially to natural features).

(12) In military use, as slope position, a drill command referring to the position in which a long-arm should be held.

1495–1505: From Middle English slope (go in an oblique direction), from the earlier adjectival meaning “slanting”, an aphetic variant of the Middle English aslope, from the Old English aslopen, past participle of āslūpan (to slip away), the construct being a- (away) + slupan (to slip).  From 1709 slope was used to mean "to be in a slanting position", the transitive sense "place in a slanting position" having been part of the language since circa 1600.  The derogatory slang meaning "oriental person" is attested from 1948.  Slopingly is an adverb, slopingness, sloper & slope are nouns, sloped & sloping are adjectives and sloped & sloping are verbs.

The slippery slope and the thin end of the wedge

Borrowed from political science, the terms “slippery slope” and “thin end (sometimes edge) of the wedge” are sometimes used interchangeably but, while both refer to similar processes, there are nuances which distinguish the two.  The idea is that a small, minor and perhaps innocuous change or innovation affecting something can trigger a chain of events which might result in unintended consequences; in that there are similarities with chaos theory but a slippery slope is much more specific and probably lineal.  There’s often overlap between the two and the distinctions are not always absolute but circumstances usually tends more to one than the other.  Both tend to be used in political discourse by extremists and fanatics and are often example of what is called the “slippery slope fallacy” such as the argument that if gay marriage is allowed, eventually the gay people will be allowed to marry their goats.  That argument really was raised by some who claimed it wasn't an extreme position to take, pointing out that two generations earlier, those who had been opposed to the decriminalization of homosexuality because it would put society on a slippery slope towards gay marriage had been accused of raising a “slippery slope fallacy”.  All things considered, goats seem safe.  The slippery slope is also a piece of imagery adopted sometimes by black-letter-law judges who oppose judicial activism.

The difference is essentially in the dynamics driving the process.  On a slippery slope, things happen because of the inherent inertia; the notion that of sitting on a slippery slope, the slide downhill an inevitable consequence of the physics of fluid dynamics and the force of gravity.  The downward path will happen naturally.  By contrast, the model of the thin end of the wedge is that of the wedge driven into the tree.  If left there nothing will happen but if the woodsman continues to hammer the edge into the trunk, at some point, the tree will fall.  An example of the thin end of the wedge was the deployment in the early 1960s by the Kennedy administration (1961-1963) of a small number of military advisors to support the government of South Vietnam.  It had never been intended that large-scale combat operations would be undertaken in Vietnam but, step-by-step, Washington increased the commitment.  An more familiar example of the slippery slope is to adopt a rigorous diet and then allow a weekly “cheat day”.  On the first cheat day, one might have just the one chocolate biscuit but the next week it’s a biscuit and a donut and within weeks it’s packets of both.

Anthony Trollope’s (1815-1882) 1857 novel Barchester Towers is set in a tranquil and leafy town but there are few novels which, without even a threat of bloodshed, so successfully and with such subtlety impart such feelings of incipient evil and a relentless undercurrent of dread.  In Victorian novels there were many characters of dubious virtue but few not actually homicidal managed to induce in readers such feelings of unease and distaste as the slimy Reverend Obadiah Slope.

Although said to be “tall and not ill made”, Slope was “saucer-eyed”, his hair “lank, and of a dull pale reddish hue… formed into three straight lumpy masses, each brushed with admirable precision, and cemented with much grease.”  His face, “perhaps a little redder” than his hair, not unlike beef “of a bad quality”, a “redeeming feature” his nose which was “pronounced, straight, and well-formed” although marred still by “a somewhat spongy, porous appearance, as though it had been cleverly formed out of red colored cork".  The description of the nose is not without significance for it had by some been asserted that he was of lineal descent from Dr Slop, “that eminent physician who assisted at the birth of Mr Tristram Shandy, and that in early years he added an ‘e’ to his name, for the sake of euphony.”  Shandy, the eponymous character from Laurence Sterne's (1713-1768) nine volume work (1759-1757), The Life and Opinions of Tristram Shandy, Gentleman, was birthed by the “man-midwife” Dr Slop, who squashes Tristram's nose with forceps as he yanks the baby out.

Slope was the domestic chaplain to Bishop Proudie at Barchester and began as a protégé of the Bishop’s wife (a truly ghastly woman) but later became her enemy as he attempted when he endeavored to wrest the control of the diocese from her hands by becoming an eminence (pâle) rouge, a kind of vicarage Richelieu controlling the Bishop.  The plots and schemes of the calculating chaplain, conducted with much obsequiousness, play out in the novel as a part of a struggle between those of the high church and the evangelicals, a struggle not resolved to this day.  The Trollope aficionados don’t regard Barchester Towers as his best work but few deny it’s one of the most enjoyable and anyone who wishes to sample Trollope should start here.

Polysphere

Polysphere (pronounced pol-ee-sfeer)

(1) In mathematics, a product of spheres.

(2) In mechanical engineering, a design of combustion chamber formed by the two shallow concave domes under the intake and exhaust valve seats.

1955: A compound word, the construct being poly + sphere.  Poly is from the Ancient Greek πολύς (polús or polys) (many, much), from the primitive Indo-European polhiús (much, many) from the root pele (to fill), akin to the Old English fela (many).  Sphere is from the Middle English spere, from the Old French spere, from the Late Latin sphēra, from the Classical Latin sphaera (ball, globe, celestial sphere), from the Ancient Greek σφαῖρα (sphaîra) (ball, globe), of unknown origin.  Despite spread of the myth by some medieval writes, sphere is not related to superficially similar Persian سپهر‎ (sepehr) (sky).  Poly, in modern English (especially in industrial and scientific application) use became a word-forming element meaning "many, much, multi-, one or more" with derivatives referring to multitudinousness or abundance.  It was equivalent to the Latin multi- and should properly be used in compounds only with words of Greek origin but this, etymologically slutty English ignores.  Polysphere is a noun and polyspheric is an adjective; the noun plural is polyspheres.

Chrysler, the poly, the hemi and the hemi which is really a poly

Chrysler didn’t invent hemispherical combustion chambers but they certainly made a cult of them.  In internal combustion engines of the mid-late twentieth century, the hemispherical combustion chamber was one of the best designs with with to provide an efficient burn-space while minimizing thermal loss and permitting the use of large diameter canted-valves to optimize intake and exhaust flow.  The early Chrysler Hemi V8s (1951-1958) were the most powerful of their generation but there were drawbacks.  To take advantage of the large valves at diverging angles, the valve train assembly was both bulky and heavy, needing two rocker shafts rather than the single units used with in-line arrangements.  Adding to the cost and complication were the inherently more expensive casting and machining processes required to produce the hemispherical shape of the combustion chambers in the cylinder heads.  To enable the mass-production of a less expensive V8 to use in their lower-priced lines, Chrysler created new cylinder heads with polyspheric (two shallow concave domes under the valves and named the “Poly”) combustion chambers and a less elaborate system of valve activation which needed only a single rocker shaft.  Although less powerful than the Hemis, the Polys were cheaper and lighter although it wouldn’t be until the 1960s that Chrysler standardized engines across their divisions; an early adoption of such economies of scale might have saved the corporation more money than retaining an exclusively Hemi-headed line would have cost.

The Hemi, 1951-1958 & 1964-1971 (left), the polyspheric, 1955-1967 (centre) and the new "Hemi" which is really a swirl Chamber, 2003- (right).

However, the Poly proved a cul-de-sac.  In an era of cheap petrol, larger capacity engines proved a more attractive route to horsepower than sophisticated combustion chamber design and the Hemis were retired in 1958, replaced by larger engines with wedge-shaped chambers, used by other manufacturers and much more suited to mass-production.  Consigned to the grave with the Hemis were almost all the Polys, only the 318 V8 (5.2 litre) retained as a rare oddity until 1967.  The Hemi would return, available between 1964-1971 as a 426 cubic inch (7.0 litre) race engine (there were also some reduced displacement versions to satisfy local rules) which, for homologation purposes would in 1966 be released in slightly detuned form detuned for street use.  The name however held such an allure that it was revived in 2003 for Chrysler's new (and perhaps final) generation of V8s although in the narrow technical sense, Hemi is now more a marketing than an engineering term because the twenty-first century combustion chambers are something of a hybrid of hemispheric and polyspheric, the general term describing them for the last fifty-odd years being swirl chambers, a design which makes possible a high out-output of power, low emissions and an economy in operation which would have been thought impossible to achieve as recently as the 1980s.

Lindsay Lohan with polyspheric hair.  Polyspheric hair styles are possible, the classic example of which is the symmetrical “twin dome” look which is difficult exactly to achieve and harder still to maintain for more than a brief time.  They’re thus seen usually only at photo-shoots or for one-off events but the design element is popular with asymmetric styles.

When Chrysler in 1964 introduced the 273 cubic inch (4.5 litre) V8 as the first of its LA-Series (that would begat the later 318, 340 & 360 (the V10 Magnum used in the Dodge Viper is also as descendent)), the most obvious visual difference from the earlier A-Series V8s was the noticeably smaller cylinder heads.  The A engines used as skew-type valve arrangement in which the exhaust valve was parallel to the bore with the intake valve tipped toward the intake manifold (the classic polyspherical chamber).  For the LA, Chrysler rendered all the valves tipped to the intake manifold and in-line (as viewed from the front), the industry’s standard approach to a wedge combustion chamber.  The reason for the change was that the decision had been taken to offer the compact Valiant with a V8 but it was a car which had been designed to accommodate only a straight-six and the wide-shouldered polyspheric head A-Series V8s simply wouldn’t fit.  So, essentially, wedge-heads were bolted atop the old A-Series block but the “L” in LA stood for light and the engineers wanted something genuinely lighter for the compact (in contemporary US terms) Valiant.  Accordingly, in addition to the reduced size of the heads and intake manifold, a new casting process was developed for the block (the biggest, heaviest part of an engine) which made possible thinner walls.  With the exception of the Hemis, the new big-block engines used wedge-heads and the small block polyspheres (the A-Series) were replaced by the LA except for an export version of the 313 (5.1 litre) which in small numbers was manufactured until 1965 and the 318, the last of which was fitted in 1967.  Confusingly, the replacement LA engine was also a 318, a product of carrying over certain components, both the 318-A & 318-LA sharing the same bore & stroke.  In an example of production-line rationalization, when Chrysler Australia bored out their 245 cubic inch (4.0 litre) Hemi-6 to create the 265 (4.3), the bore chosen was the same as the 318s so pistons could have been shared with the V8 although for technical reasons this wasn't actually done.  The Australian "Hemi" straight sixes used another variation of the combustion chamber in that chambers sat in upper third of the globe, hence the "low hemispherical" slang which wasn't wholly accurate but Ford's Boss 429 V8 had already been dubbed the "semi-hemi" and linguistic novelty was becoming hard to find.

Allegro

Allegro (pronounced uh-ley-groh or uh-leg-roh or ahl-le-graw (Italian)).

(1) In music, a tempo mark directing that a passage is to be played in a quick, lively tempo, faster than allegretto but slower than presto.

(2) In music (more traditionally), an expressive mark indicating that a passage is to be played in a lively or happy manner, not necessarily quickly.

(3) In music, a piece or passage to be performed in this manner (an allegro movement).

(4) In printing & typography, as the font Allegro, a serif typeface released in 1936.

1625–1635: From the Italian allegro (lively; happy, cheerful (feminine allegra, masculine plural allegri, feminine plural allegre, superlative allegrissimo)), from the French allègre, from the Latin alacer (nominative alacer) (lively, cheerful, brisk) (from which English later picked up alacrity).  The Italian allegretto (diminutive of allegro) in musical composition is the instruction to be (brisk & sprightly but not so quick as allegro) was coined in 1740 explicitly for its technical purpose in music.

Use as a musical term didn’t actually begin until 1721.  Prior to that, since the early seventeenth century, English had used the word in the sense (brisk, sprightly; cheerful) picked up from Italian and Latin although the original spelling in English was aleger (lively, brisk) from Old French alegre, influenced by the Medieval Latin alacris.  What encouraged the use was the adoption of the word (in its literal sense) by John Milton who in 1632 published the poem L'Allegro".  Apart from the use in musical composition, there’s also allegro speech, a relatively fast manner of speaking, once often used as a stage notation by playwrights although it seems now less common, replaced by terms better known to the young.  As well as the native Italian and the English allegro, composers in many languages use the term including in French allegro (the post-1990 spelling allégro), the Greek αλέγρος (alégros) & αλλέγκρο (allégkro), the Norwegian allegro, the Portuguese allegro (the alternative spelling alegro), the Turkish allegro and the Persian آلگرو.  Allegro is an adjective, adverb & noun, the noun plural being allegros.

Although book burning was associated with the era, much publishing was still done in Germany during the 1930s and the centre of the industry was Frankfurt.  In 1936 the city’s Ludwig & Mayer type foundry released the Allegro typeface, in the tradition of the nineteenth century Didone style but influenced also by the art deco designs which had become popular.  A serif design which relied for its effect on the alternation of thick and thin strokes, it uses breaks in the letter where thin strokes might be expected, hinting at the style of stencils with a touch of the inclination associated with calligraphy.  It was a popular typeface for decorative purposes such as book jackets or headings of musical notation but very much a display font, it works well only above a certain point size and is used almost exclusively for titles.

Aesthetic success & failure: The Alfa-Romeo Alfasud (left) and the Austin Allegro (right).

Often featured (usually with several other products of British Leyland in the 1970s) in lists as among the worst cars ever made, the Austin Allegro was in production between 1973-1982 and actually sold in respectable numbers for most of that time although at only a third the rate of its remarkably popular predecessor (ADO16, the Morris 1100/1300 and its many badge-engineered siblings).  One much criticized aspect of the Allegro was the appearance; it was thought a bloated blob in an era of sharp-edged wedges and the critique does illustrate just how narrow can be the margin between success and failure in the execution of a concept.  The Alfa Romeo Alfasud (1971-1983 (variants of the original produced until 1989)) adopted essentially the same shape and dimensions yet was praised as an elegant and well-balanced design.  Seen in silhouette, the shapes are similar yet in the metal, the detail differences, a mere inch (25 mm) or two here and there or a subtle change in an angle or curve and one emerges lithe and the other ponderous.

The Allegro’s portly appearance wasn’t the original intent.  Tasked with designing a replacement for ADO16, the stylist Harry Mann (1938-2023) sketched a modernist wedge, designed to accommodate what was at the time an advanced specification which included all-independent hydraulic suspension, front wheel drive, disk brakes and crucially, new, compact engines.  Mann however began the project while employed by Austin’s parent corporation, the British Motor Corporation (BMC) but by the time substantive work on the Allegro began, BMC had been absorbed into the Leyland conglomerate, a sprawling entity of disparate and now competing divisions which, if agonizingly reorganized, might have succeeded but such were the internal & external obstacles to re-structuring that, coupled with political turmoil and the economic shocks of the 1970s, it staggered to failure, something the later nationalization could only briefly disguise.  Thus Mann’s team learned the clean-lined wedge would have to be fattened-up because not only were the old, tall engines to be re-used but the new engines to be offered as options were bulkier still.  Installed at an angle, which would have demanding some re-engineering but would have been possible, that might have been manageable but what was not was the decision to use the corporate heater unit, developed at an apparently extraordinary cost; it could be installed just one way and it was a tall piece of machinery.

1976 Triumph TR7 Coupé.

Mann didn’t forget his 1968 sketch and when the opportunity later came to design a new sports car, his wedge re-appeared as one of the cars which most represented the design ethos of the 1970s: The Triumph TR7 & TR8 (1975-1982) which would have their own troubled history but which sold quite well and, as the TR8 (which used the 3.5 litre (215 cubic inch) River V8), represented something in which the potential of the original was finally realized but it was too late for by then the disaster that was British Leyland had eaten itself.

The Allegro is remembered also for a steering wheel which was neither circular yet not exactly square.  Actually the idea wasn’t novel, dating back decades and had been used on quite a few American cars during the early 1960s but on the Allegro it attracted much derision, something not diminished by Leyland’s explanation that it was optimal for the car and afforded a good view of the instruments.  Leyland also attracted the scorn of mathematicians when they called the shape “quartic” because of it being “a square with rounded corners”.  The nerds pointed out quartic meant “an algebraic equation or function of the fourth degree or a curve describing such an equation or function” and the word Leyland was searching for was "squircle" (in algebraic geometry "a closed quartic curve having properties intermediate between those of a square and a circle").  Leyland ignored them but soon replaced the wheel with a conventional circular design.  Whatever the name, variations of the shape have since become popular with high-end manufacturers, Ferrari, Aston-Martin, Lamborghini and others all pursuing non-circular themes and one is a feature of the latest (C8) mid-engined Chevrolet Corvette.

The fate of many Alfasuds.

The Alfasud name (the construct being Alfa + sud) was an allusion to it being produced in a newly built factory in the Naples region, the decision taken after financial inducements were offered by the government, anxious to do something about the levels of unemployment and lack of economic development in the south of the country.  The Italian sud (south) was from the French sud, from Old English suþ, from Proto-Germanic sunþrą.  As a plan it made sense to politicians and economists but, industrial relations being what they were at the time, the outcome was less than ideal.    

In one aspect, the Allegro and Alfasud were wholly un-alike, the latter infamous for its propensity to rust, a trait shared with many mass-produced Italian cars of the era, the only consolation for Alfasud owners being the contemporary Lancia Beta suffered even more.  The Alfasud's rust-resistance did improve over the years but it remained a problem until the end of production and the industry story has always been that in the barter economy which was sometime conducted between the members of the EEC (European Economic Community, an ancestor organization of the latter-day European Union (EU)) and those of the Warsaw Pact (the alliance between the USSR and its satellite states which essentially duplicated the structure of the North Atlantic Treaty Organization (NATO)), Italian manufactured goods were exchanged for Russian steel which was reputedly re-cycled but anyway turned out to be of poor quality and essentially porous.  The story certainly is a good fit for the narrative of maladministration and corruption that was Italy in the 1970s but subsequent research has revealed it to be a myth, the sheet metal used in the Neapolitan factory at Pomigliano d’Arco where Alfasuds were made the same stuff that Alfa Romeo used in the facility at Arese in Milan where the Giulia range was produced and their reputation for resisting rust was good.  The evidence suggests all the steel used by the company's local operations came from the state owned Taranto steel mills.  Intriguingly, the factories south & north all used the same paints and the ovens & paint booths were a decade-odd newer in Naples.

Given all that, the startlingly premature corrosion surprised many within Alfa Romeo and in 1977 a project-team began to investigate the causes and it was afforded some urgency given the reputational damage being suffered by the whole company (ie profits were suffering).  Having determined the core components (paint & steel) weren't to blame, the engineers deconstructed the production process including the system of movement (how the partially completed cars proceeded from start to finish).  What the team found was that while the electrophoresis baths at Pomigliano were state of the art, the inexperienced (and sometimes indifferently-minded) workforce operated them without adequate supervision and quality control, something exacerbated by the chronically bad labor relations, the factory beset by rolling strikes which meant unpainted bodies were often sitting for days.  In the humid climate of the south, condensation gathered, many cars already rusting even before eventually receiving a coat of paint and that the plant was less than 10 miles (16 km) from the coast and the prevailing winds blew from the sea added to the problem, the unpainted Alfasuds often left for days damp with salty moisture.

The team's findings resulted in a change to the production process for the revised Series 2 Alfasuds launched in December 1977.  The critical parts of the bodyshell now used "Zincrometal" (steel coated with a primer which was a mix of chromium, zinc and an organic bonding resin, baked at 160°C (320°F) which was as good as anything used in the industry.  As a added precaution, a polyurethane foam was injected into the body's boxed sections with a flexible plastic sealant applied at the seams to prevent moisture intrusion.  That had the added benefit of reducing noise vibration & harshness (NVH) while adding little extra weight.  Unfortunately, the tests the engineers conducted to prove the design was waterproof relied on perfectly applied sealant at the junctions but the poor quality control continued and many seams were poorly sealed which meant the foam acted as a moisture store, making the problem worse.  By contrast, whatever its other faults, and there were a few, the Allegro resisted rust like few cars built anywhere during the era, the design sound and that 1970s British Leyland paint thick and durable.  In the years that followed, many would criticize the sometimes lurid and even sickly shades but as a protective coating, it did the job.

How to make an Allegro look worse: 1976 Vanden Plas 1500.

In another sign of the times, unlike ADO16, one basic vehicle which was badge-engineered to be sold under six brands (Austin, Morris, Riley, Wolseley, MG & Vanden Plas), the only variation of the Allegro was a luxury version by Vanden Plas, laden with leather, cut-pile carpeting and burl walnut trim including the picnic tables on the back of the seats so beloved of English coachbuilders.  It didn't use the Allegro name and has always elicited condemnation, even from those who admired the Vanden Plas ADO16, presumably because the traditional upright grill attached to the front suited the earlier car's lines whereas the version which had to be flattened to fit the Allegro's pinched, pudgy nose looked just absurd.  Still, there's clearly some appeal because the Vanden Plas cars have the highest survival rate of all the Allegros and now enjoy a niche (one step below the GDR's (the German Democratic Republic; the old East Germany) Trabant) on the bottom rung of the collector car market.
