Latex

Latex (pronounced ley-teks)

(1) A sometimes colorless, sometimes milky liquid containing protein, starch, alkaloids etc in certain plants, which exists in plants such as milkweeds, euphorbias, poppies, or the plants yielding India rubber, that coagulates on exposure to air.

(2) In chemistry, a suspension of synthetic rubber or plastic in water, used in the manufacture of synthetic rubber products.

(3) In industrial chemistry, a manufactured emulsion of synthetic rubber or plastic droplets in water that resembles the latex of plants. It is used in paints, adhesives, and synthetic rubber products.

(4) A general term, used as noun or adjective for latex products.

(5) In ancient medicine, clear liquid believed to be a component of a humor or other bodily fluid, especially plasma and lymphatic fluid (obsolete).

(6) In computing, as LaTeX, a digital typesetting system for mathematical and scientific formulae layout, based on the code of TeX.

1655–1665: From the Medieval Latin latex (genitive laticis) (clear fluid which is part of a humour or bodily fluid), a variation of the Classical Latin latex (water; liquid, fluid) which may be from the Ancient Greek λᾰ́τᾰξ (látax) (dregs or a drop of wine), from the primitive Indo-European root lat (wet; moist) but etymologists note the semantic shift from "drop of wine" to "water" is undocumented and may indicate origins from separate languages.  It’s also speculative that the Old & Middle Irish laith (liquid; beer), the Old High German letto (clay, loam), the Welsh llaid (mud, mire) & llad (beer), the Proto-Celtic lati-, Proto-Germanic ladjō-, the Old Norse leðja (mud, dregs), the Lithuanian latakas (pool, puddle) and the Old Norse leþja (filth) are related.

From 1835 the word was used in the sense of "the milky liquid from plants", the meaning "water-dispersed polymer particles" as used in rubber goods, paints and other industrial products) dating from from 1937.  Latex was first noted as an adjective in 1954 as a popular (and more convenient) substitute for the classically correct laticiferous.  Thoughtfully, the developer of LaTeX (the TeX-based digital typesetting system) provided a pronunciation guide, the final consonant of TeX pronounced similar to loch or Bach.  The letters of the name represent the capital Greek letters Τ (tau), Ε (epsilon), and Χ (chi), as TeX is an abbreviation of Ancient Greek τέχνη (tékhnē) (the root word of "technical").  Inevitably however, English speaking nerds who haven't read the guide often pronounce it tekThe noun latexosis is used to refer to an abnormal flow of latex from a plant.  Latex is a noun & adjective; the noun plural is latexes.

Notes on Latex

Latex is a natural material that requires special care not necessary for fabrics. It is sensitive to external factors that cause tearing, discoloration or weakening.

What to avoid

Oil: Oils will degrade latex so avoid any contact with oil-based fluids or solvents, hand creams, grease, leather etc. Always handle latex with clean hands.

Metal: Latex will react with copper, brass and bronze, resulting in stains; even handling these metals before touching light colored latex may result in discoloration.

Sunlight, heat and humidity: Exposure to sunlight or other UV light sources will cause white patches where the color has been bleached, dark colors being especially prone to this.  Exposure to heat and humidity may result in discoloration or degradation.  Latex is flammable and should not be exposed to raised temperatures; this includes radiators, heat sources and tumble dryers.

Rita Ora in Latex, London, January 2023.

Sharp objects:  Any sharp object can puncture or tear latex so observe particular caution with long fingernails; those required frequently to handle latex are recommended to wear cotton or latex gloves.

Flame:  Latex is flammable; it must not be exposed to flame.

Ozone: Ozone is produced from oxygen by UV-radiation from the big industrial fluorescent lamps.  Prolonged storage without a protecting bag will lead to damage not unlike sunlight, the consequences being discoloration and brittleness.

Polishing

Latex can be rendered in a matte or polished finish.  To achieve a shine, coat surface in a silicone lubricant or other latex polish; this may be sprayed or spread, either with bare hands or a soft, lint-free cloth (Don't rub too hard; this can damage latex.  With transparent latex, applying the liquid to both sides will enhance the transparency.

Cleaning

Latex should regularly be cleaned by rinsing well in warm water.  Some manufacturers recommend using a mild soap, while others suggest only water, the general principle being to follow their recommendations.  To dry, hang on a plastic or wooden hanger or lay flat; latex can be wiped gently with a soft towel to decrease drying time if desired.  When one side is dry, turn inside out and let the other side dry.  When completely dry, separate any latex that has stuck together and lightly dust with talc powder to prevent any further sticking (manufacturers caution against using liquids for this purpose).

Storage

Prepare latex for storage by washing, drying and lightly powdering as described in the cleaning routine.  Ideally, latex should be kept in a black plastic bag in a cool, dry place.  Light and dark pieces of latex should not be stored in direct contact as this can cause discoloration of the lighter.

Cybernetic

Cybernetic (pronounced sahy-ber-net-ik)

(1) Of or relating to cybernetics (the theoretical study of communication and control processes in biological, mechanical, and electronic systems, especially the comparison of these processes in biological and artificial systems).

(2) Of or relating to computers and the Internet (largely archaic (ie "so 1990s").

1948 (in English): From the Ancient Greek κυβερνητικός (kubernētikós) (good at steering, a good pilot (of a vessel)), from κυβερνητική τέχνη (kubernētikḗ tékhnē) (the pilot’s art), from κυβερνισμός (kubernismós) or κυβέρνησις (kubérnēsis) (steering, pilotage, guiding), from κυβερνάω (kubernáō) (to steer, to drive, to guide, to act as a pilot (and the ultimate source of the Modern English "govern").  Cybernetic & cybernetical are adjectives, cybernetics, cyberneticist & cybernetician are nouns and cybernetically is an adverb; the noun cybernetics is sometimes used as a plural but functions usually as a as singular (used with a singular verb)  

Although it's undocumented, etymologists suspect the first known instance of use in English in 1948 may have been based on the 1830s French cybernétique (the art of governing); that was in a paper by by US mathematician and philosopher Norbert Wiener (1894-1964) who was influenced by the cognate term "governor" (the name of an early control device proposed by Scottish physicist James Clerk Maxwell (1831–1879)), familiar in mechanical devices as a means of limiting (ie "governing") a machine's speed (either to a preferred rate or a determined maximum).  That was obviously somewhat different from the source in the original Greek kubernētēs (steersman) from kubernan (to steer, control) but the idea in both was linked by the notion of "control".  The French word cybernétique had been suggested by French physicist and mathematician André-Marie Ampère (1775-1836), (one of the founders of the science of electromagnetism and after whom is named the SI (International System of Units) unit of measurement of electric current, the ampere (amp)) to, describe the then non-existent study of the control of governments; it never caught on.  From cybernetics came the now ubiquitous back-formation cyber which has, and continues, to coin words, sometimes with some intellectual connection to the original, sometimes not: cybercafé, cybercurrency, cybergirlfriend, cybermania, cybertopia, cyberculture, cyberhack, cybermob, cybernate, cybernation, cyberpet, cyberphobia, cyberpunk, cybersecurity, cybersex, cyberspace, cyberfashion, cybergoth, cyberemo, cyberdelic et al.

Feedback

MIT Professor Norbert Wiener was an American mathematician and philosopher and one of the early thinkers developing the theory that the behaviour of all intelligent species was the result of feedback mechanisms that perhaps could be simulated by machines.  Now best remembered for the word cybernetics, his work remains among the foundations of artificial intelligence (AI).

The feedback loop at its most simple.

Cybernetics was an outgrowth of control theory, at the time something of a backwater in applied mathematics relevant to the control of physical processes and systems.  Although control theory had connections with classical studies in mathematics such as the calculus of variations and differential equations, it became a recognised field only in the late 1950s when the newly available power of big machine computers and databases were applied to problems in economics and engineering.  The results indicated the matters being studied manifested as variants of problems in differential equations and in the calculus of variations.  As the computer models improved, it was recognised the theoretical and industrial problems all had the same mathematical structure and control theory emerged.  The technological determinism induced by computing wasn’t new; the embryonic field had greatly been advanced by the machines of the eighteenth and nineteenth centuries.

Cybernetics can be represented as a simple model which is of most use when applied to complex systems.  Essentially, it’s a model in which a monitor compares what is happening with what should be happening, this feedback passed to a controller which accordingly adjusts the system’s behavior.  Wiener defined cybernetics as “the science of control and communications in the animal and machine”, something quite audacious at the time, aligning as it did the working of machines with animal and human physiology, particularly the intricacies of the nervous system and the implication the controller was the human brain and the monitor, vision from the eyes.  While the inherently mechanistic nature of the theory attracted critics, the utility was demonstrated by some success in the work of constructing artificial limbs that could be connected to signals from the brain.  The early theories underpinned much of the early work in artificial intelligence (AI).

Of cyberpunks and cybergoths

The youth subcultures “cyberpunk” and “cybergoth” had common threads in the visual imagery of science fiction (SF) but differ in matters of fashion and political linkages.  Academic studies have suggested elements of cyberpunk can be traced to the dystopian Central & Eastern European fiction of the 1920s which arose in reaction to the industrial and mechanized nature of World War I (1914-1918) but in its recognizably modern form it emerged as a literary genre in the 1980s, characterized by darkness, the effect heightened by the use of stark colors in futuristic, dystopian settings, the cultural theme being the mix of low-life with high-tech.  Although often there was much representation of violence and flashy weaponry, the consistent motifs were advanced technology, artificial intelligence and hacking, the message the evil of corporations and corrupt politicians exploiting technology to control society for their own purposes of profit and power.  Aesthetically, cyberpunk emphasized dark, gritty, urban environments where the dominant visual elements tended to be beyond the human scale, neon colors, strobe lighting and skyscrapers all tending to overwhelm people who often existed in an atmosphere of atonal, repetitive sound.

Cybergoth girls: The lasting legacy of the cybergoth's contribution to the goth aesthetic was designer colors, quite a change to the black & purple uniform.  Debate continues about whether they can be blamed for fluffy leg-warmers.

The cybergoth thing, dating apparently from 1988, thing was less political, focusing mostly on the look although a lifestyle (real and imagined) somewhat removed from mainstream society was implied.  It emerged in the late 1990s as a subculture within the goth scene, and was much influenced by the fashions popularized by cyberpunk and the video content associated with industrial music although unlike cyberpunk, there was never the overt connection with cybernetic themes.  Very much in a symbiotic relationship with Japanese youth culture, the cybergoth aesthetic built on the black & purple base of the classic goths with bright neon colors, industrial materials, and a mix of the futuristic and the industrial is the array of accessories which included props such as LED lights, goggles, gas masks, and synthetic hair extensions.  Unlike the cyberpunks who insisted usually on leather, the cybergoths embraced latex and plastics such as PVC (polyvinyl chloride), not to imitate the natural product but as an item while the hairstyles and makeup could be extravagantly elaborate.  Platform boots and clothing often adorned with spikes, studs and chains were common but tattoos, piercings and other body modifications were not an integral component although many who adopted those things also opted to include cybergoth elements. 

Although there was much visual overlap between the two, cyberpunk should be thought of as a dystopian literary and cinematic genre with an emphasis on high-tech while cybergoth was a goth subculture tied to certain variations in look and consumption of pop culture, notably the idea of the “industrial dance” which was an out-growth of the “gravers” (Gothic Ravers), movement, named as goths became a critical mass in the clubs built on industrial music.  While interest in cyberpunk remains strong, strengthened by the adaptability of generative AI to the creation of work in the area, the historic moment of cyberpunk as a force in pop culture has passed, the fate of many subcultures which have suffered the curse of popularity although history does suggest periodic revivals will happen and elements of the look will anyway endure.

Doppelganger

Doppelganger (pronounced dop-uhl-gang-er or daw-puhl-geng-er (German))

(1) In legend, a ghostly apparition of a living person, especially one that haunts such a person.

(2) A counterpart of a living person, identical in appearance; a person remarkably similar in appearance to another.

(3) In the pop-culture fantasy genre, a monster that takes the forms of people, usually after killing them.

(4) An evil twin (often as alter ego)

1826 (1824 as a German word in English): From the German Doppelgänger, literally "double-goer" or “double walker” originally with a ghostly sense.  Although now less common, it was once sometimes the practice to use the half-English spelling doubleganger.  Doppel was from doppelt (double), from doppeln (double (made up of two matching or complementary elements)), from the Old French doble (to double), from the Latin dūplus, from the Proto-Italic dwiplos, the construct being duo (two) +‎ plus, from the Old Latin plous, from the Proto-Italic plous, from the primitive Indo-European pleh- & pelhu- (many) and cognate with the Ancient Greek πολύς (polús) (many) and the Old English feolo (much, many).  It was influenced by the Ancient Greek διπλόος (diplóos) (double), the construct being δι- (di-), from δύο (dúo) (two), + -πλόος (-plóos) (-fold) and the Proto-Germanic twīflaz (doubt). A doublet of Zweifel.  Gänger was from Middle High German genger (to go, to walk), the construct being Gang +‎ -er.  Gang was from the Middle High German ganc, from the Old High German gang, from the Proto-Germanic gangaz (pace, step, gait, walk) and cognate with the English gang.  The synonyms in the various senses include double, lookalike, dead-ringer & alter ego.

Kim Jong-un, 2019-2020.

Rumors that Kim Jong-un (b circa 1994, Supreme Leader of the Democratic People’s Republic of Korea (North Korea, the DPRK) since 2011) was incapacitated with (unspecified) health problems spiked in late 2021 when he appeared looking notably thinner than in his appearances only months earlier, the conspiracy theory hinging on the idea the part of the Supreme Leader was being played by a doppelganger.  Most speculation centered on Mr Kim’s apparently chronic obesity, chain smoking and legendarily enthusiastic intake of his favorite Swiss cheese, some suggesting the doppelganger would fulfill the role until a team of foreign doctors working in secret restored the Supreme Leader to good working order while others opined he may actually be dead and the elite of the ruling Workers' Party of Korea (the WPA, a kind of cross between the a communist party and the Kim family’s holding company) was just buying time while they worked out what to do next.

Noted DPRK watchers, the National Intelligence Service (NIS), the Republic of Korea's (South Korea, the ROK) spy agency, dismissed the idea and said the new, sexy, slimmed-down Supreme Leader was real, their findings based on a comparison using facial recognition software, weight-tracking models and analysis of high-resolution video.  According to the NIS, Mr Kim’s weight which by 2019 had reached 142 kg (313 lb), less than a year later had further ballooned to around 146 kg (322 lb) while his appearances in late 2021 indicated a loss of between 20-25 kg (44-55 lb).  They added he appeared to be in rude good health.

Kim Jong-un, 2021.

If that’s true, the weight-loss could be accounted for either by Mr Kim’s desire to slim down for reasons of health or may be political, the DPRK facing one of its worst food shortages in many years and he may wish to convey the impression he’s sharing in the deprivations being suffered by his people.  Various seasonal factors would anyway have squeezed the food supply but the COVID-19 measures taken certainly exacerbated the problem, the closure of the borders inducing the sharpest economic contraction since the loss in the early 1990s of economic assistance from the Soviet Union.  The DPRK’s trade with its main trading partner, the People’s Republic of China (PRC), dropped by between 80-90% from pre-pandemic levels and the NIS noted it was the “mismanagement” of the economy which had caused inflation rates to surge beyond that afflicting all but a few other countries but, with a chronic shortage of ink and paper, the DPRK was unable to resort to the short-term expedient of printing money.  Still, things appear not actually on the point of collapse, ballistic missile tests continuing and the COVID-19 policy has, as stated by official DPRK propaganda, proved an outstanding success, Pyongyang confirming the country has suffered zero cases since the pandemic began.  It does seem to prove a “shoot to kill” border policy works, something a few Western politicians have long suspected and probably longed for.

Kim Jong-un looking at morning tea.

Targeted sanctions imposed in response to the regime’s nuclear weapons recalcitrance had already resulted in some humanitarian suffering but the closure of the PRC-DPRK border and has increased this by blocking shipments of grain, fertilizer and farming equipment.  Severe flooding caused by powerful typhoons in 2020 which so lowered that year’s harvest also had effects which lingered, crop yields again very low in 2021.  It had become so bad that in a rare public admission, Mr Kim in 2021 told a Worker’s Party meeting that the “people’s food situation is now getting tense” and his immediate policy switch was to order all citizens to devote all their effort to farming, making sure to secure “every grain” of rice.  With apparently all NGO and UN staff having left the country, most sources of foreign aid have evaporated and the DPRK is more dependent on its own resources than at any time since the end of the Korean War (1950-1953).  All this might explain Mr Kim’s weight-loss, although not yet obviously malnourished, he’s at least setting an example.

Manchu Tuan, Shenyang, PRC (left) and the Supreme Leader (right).

In general circulation, Kim Jong-un doppelgangers are not actually rare, at least two known to be available for hire from talent agencies.  Regardless of what happens in the DPRK, it may be a good gig because in 2012, satirical site The Onion named Kim Jong-un the world’s sexiest man, either because he was, in their words, “devastatingly handsome” or a nod to Henry Kissinger’s (b 1923; US secretary of state 1973-1977) claim (actually probably a boast) that “power is the ultimate aphrodisiac”.  The Onion’s winner in 2011 had been Syrian dictator Bashar al-Assad (b 1965; president of Syria 2000-) so the editors may have found Dr Kissinger persuasive.  Manchu Tuan sells kebabs in the north-eastern Chinese city of Shenyang and says business has boomed since this resemblance to Mr Kim appeared on social media and he has hired another cook to prepare the kebabs, much of his time now absorbed with customers taking selfies with him.

Shao Jianhua, who five years ago moved from his native Zhejiang to Changsha, makes and sells meat pies with dried and pickled vegetables, a dish associated with costal Zhejiang.  His shop operates from a cluster near the university halls of residence and the students, although very fond of his highly-regarded pies, also request selfies, business having expanded since word spread of his resemblance to PRC president Xi Jinping (b 1953; PRC president 2013-).  Mr Shao, whose pies sell for 3.5 yuan (US$0.55) has increased production to 1,600 a day during peak season and the queues are frequently long.

The conspiracy theorists do apply some science to their subjects.  Of particular interest are ears, cosmetic surgeons noting that ears are so difficult to modify to match those of another person and that latex versions attached with surgical glue are the best solution for these purposes although even with these there are limitations.  It’s not the first time a head of government’s ears have attracted interest.  In 1939, Adolf Hitler (1889–1945; Führer of Germany 1933-1945) sent his court photographer Heinrich Hoffmann (1885–1957) with the party which in 1939 went to Moscow to execute the Nazi-Soviet Pact, his task, inter alia, to get a good shot of Comrade Stalin’s (1878-1953; Soviet leader 1924-1953) ear-lobes, the Führer wishing to be reassured his new (and temporary) ally’s lobes were “separate and Ayran” and not “attached and Jewish”.  He was satisfied with Hoffman’s evidence but that didn’t stop him later double-crossing Stalin.

The flight to England by Rudolf Hess (1894–1987; Deputy Führer 1933-1941) in 1941, an attempt to persuade the British to conclude the war on the eve of the invasion of Russia, was one of the strangest episodes of the war and whether or not his flight was approved by Hitler remained a matter of conjecture for decades although the available evidence does suggest the Führer was as shocked as everyone else.  Another conspiracy theory ran for years, that of whether the Hess the British produced for trial in Nuremberg (1945-1946) and who was subsequently imprisoned in Spandau until his suicide (other conspiracy theories explore this) in 1987 was actually a doppelganger.  Books with various explanations about why the British might have done this were written, including one by a doctor who examined Hess while a prisoner and couldn’t reconcile his physiology with the injuries he’s suffered while serving in the Imperial Army in the First World War.  Eventually even the suspicious authors conceded the incarcerated Hess was the real one and in 2019, after one of Hess’s hermetically sealed blood samples was discovered and subjected to a DNA analysis which found a 99.99% likelihood of a match with one of Hess’s living relatives.

Lindsay Lohan and body double during filming of Irish Wish (Netflix), scheduled for release in 2023.

The most obvious doppelgangers are "body doubles", actors used when filming scenes when, for whatever reason, the lead actor can't be used.  Such are the tricks and techniques of film production, the body doubles don't have to be even close to exact doppelgangers, they need only be vaguely similar though they often share some distinctive characteristic (such a long red hair).  Generally, body doubles are used for three reasons:

(1) Dangerous stunts: Body doubles with specific expertise are often hired to perform dangerous scenes, such as car chases, fight scenes, or jumps from great heights.

(2) Time constraints: In some cases, the lead actor or actress may not be available to film certain scenes due to scheduling conflicts.  In these situations, a body double can be used to film the scene in their place, allowing production to continue without delay.

(3) Privacy: In some instances, actors may not wish to appear in certain scenes, typically those involving nudity.  Sometimes contractual clauses include these stipulations.

Manikin & Mannequin

Manikin (pronounced man-i-kin)

(1) A man short in stature; (sometimes as a term of endearment but now archaic).

(2) In folklore, a dwarf; pygmy.

(3) An anatomically correct model of the human body (or a part of the body), used for teaching or demonstrating surgical and other clinical techniques; a specialized form is the phantom, an anatomical model of a fully developed fetus, for use in teaching midwifery or obstetrics.

(4) A three-dimensional figure, dummy or effigy representing a man or person (now replaced by mannequin), manikin now correctly used only in the medical context.

1560s: From the Dutch manneken (literally “little man”), a diminutive of the Middle Dutch mannekijn, from the Proto-Germanic manwaz, from the primitive Indo-European root man- (man).  The original meaning was "a jointed model of the human figure used by artists" and the sense and spelling is often blended with mannequin.  The early synonyms (in the context of small humans) included homunculus, midget, peewee, shorty, titman, & doll and (in the sense of the artificial creations) dummy, figure, mannequin & marionette.  The noun plural is manikins; the (rare) alternative spelling is mannikin.

Mannequin (pronounced man-i-kin)

(1) A styled and three-dimensional representation of the human form used in window displays, as of clothing; dummy.

(2) A figure or model of the human figure used by tailors, dress designers etc, for fitting or making clothes; historically made from timber but now constructed from many combinations of materials.

(3) A person employed to wear clothing to be photographed or to be displayed before customers, buyers etc; a clothes model (dated).

(4) In the visual arts, arts another name for a lay figure

1902: From the fifteenth century French mannequin (model to display clothes) from the Dutch manneken (model of the human figure used by artists).  Mannequin was the French form of the same word that yielded manikin and in English, was sometimes used in the sense "artificial man" (especially in translations, the trend apparently triggered by the frequency of use in early twentieth century translations of the works of Victor Hugo (1802–1885)).  Originally, it was applied to humans in the modern sense of “a model” and not until 1931 did it assume the meaning of “artificial human model figure to display clothing”.  A sideway variation was the later “clotheshorse” (a person whose chief interest and pleasure is dressing fashionably).  The noun plural is mannequins.

The difference between a Manikin and a Mannequin

Mannequin was a word once used where model would now be preferred, a person employed to wear clothes and carry accessories but since the 1930s a mannequin is a usually plastic or fibreglass emulation of the human form (in shape but not fine detail), typically found scattered throughout clothing and department stores, most famously as part of displays in shop-front windows.  Most mannequins represent a body shape within a fairly narrow range of dimensions but the industry recognizes eighteen different types including the obvious like “sexy” and “sporty” but there are also the niches such as pregnant people.

Manikins are also human shaped models but rather than being a fashion platform, they are used to help simulate medical, surgical, or clinical scenarios to assist in training and the honing of technique.  There are a variety of manikins and in the jargon of the medical devices industry, they range from low to high fidelity, the rating an indication of the degree of anatomical realism included, a high-fidelity manikin sometimes even including movement, speech, muscular reaction and facial expressions.  A high-fidelity manikin might include a complete set of internal organs and have many interchangeable parts whereas a low-fidelity model might be just a hollow shell used to teach students how to insert an IV or perfect the techniques of bandaging.

Manikins exist so those working in a clinical environment, from students to surgeons, can enjoy a safe environment in which to practice their skills, without the obvious risk of using live patients.  Although doctors continue, as they have for centuries, to murder their patients, rarely suffering any consequences due to the cozy legal apparatus known as “medical misadventure”, the use of manikins presumably lessens the slaughter of the innocent.  Like mannequins, manikins are designed for purpose and there are birthing simulators, newborn simulators, simulators that go into cardiac arrest, and even dental simulators.

L'Inconnue’s death mask.

Although anatomical models were used in medical training as early as the sixteenth century, the first manikin (in the modern understanding) was released in 1960 as a device for teaching cardiopulmonary resuscitation (CPR).  The design parameters were written by two physicians, Austrian Peter Safar (1924-2003) and American James Elam (1918–1995), the engineering and fabrication handled by Norwegan Åsmund Lærdal (1914-1981), head of a company with expertise in plastic molding from their experience as a manufacturer of children’s toys.  Famously, the face on the manikin is that of L'Inconnue (L'Inconnue de la Seine (The unknown woman of the Seine)).

Crowd at the public viewing portal of the Paris Morgue, circa 1890.

L'Inconnue, was probably about sixteen when she died in the late 1880s and although it’s not certain, most then concluded she took her own life.  As was done at the time, after her lifeless form was pulled from the River Seine at the Quai du Louvre, the corpse was put on public display at the Paris mortuary, a popular attraction and one justified by the purpose of hoping some of the dead might be identified.  Despite the daily crowd, none came forward to name L'Inconnue.  The dead waif however was far from unnoticed, many remarking on her unusually serene appearance and one much taken by her was the pathologist who performed the autopsy.  He had a plaster-cast taken of her face (a not uncommon practice) and within years, reproductions of L'Inconnue's alluring, deathly likeness were being sold throughout Europe, the mesmerizing mask, later describe by philosopher Albert Camus (1913-1960) as a "drowned Mona Lisa", fixed to the walls of drawing rooms, fashionable salons and the studios of (presumably already troubled) artists.  The silent beauty also attracted writers and early in the twentieth century there was a rash of imaginative fiction speculating about the short life of L'Inconnue, many melodramatic, most constructing a short, tragic life battered by ill fortune and finally taken by the waters of the Seine.  For writers, it was the lure of the tragic, death, water and a waif irresistibly romantic and in death she became the one of the great influencers of her age, described as “the aesthetic template for a whole generation of German girls who modeled their looks on her", adored in death as many authors liked to imagine she never was when alive.

L'Inconnue’s death mask would over the years attract artists and it’s been rendered in many materials including ceramics, copper, bronze, granite and even chocolate, seen as an icon and on canvas with a variety paints.

Decades later, L'Inconnue’s image would again be revived.  Åsmund Lærdal in the 1940s had been a manufacturer of small wooden toys but in the post-war years, attracted by the possibilities of the then novel plastic, he experimented with the soft, malleable substance and, finding it ideal for his purposes, embarked on mass-production, one of his products the acclaimed toy “Anne”, a baby with “sleeping eyes and natural hair".  Anne enjoyed international success and when told the two anesthesiologists, impressed by the life-like behavior of the doll’s plastic material, had asked if he could fabricate and mass-produce a life-sized adult manikin on which could be demonstrated their newly developed resuscitation technique, they found an attentive listener; some years earlier, Lærdal's two year old son had nearly drowned and had his father not forced the water from his airways, he too may well have died.  For a toymaker with expertise in the molding of plastic to form hollow toys, it was a formidable engineering challenge not only to create a realistic, functional maikin that reliably could be used to demonstrate the physical complexities of CPR but to design a mass-produced product which would be financially viable.

Resusci Anne in carry-case.

The technical specifications provided by the doctors had included a collapsible chest for practicing compressions and open lips to simulate mouth-to-mouth resuscitation but Lærdal, after discussions with his engineers, concluded it was also important the manikin should be recognizably female, suspecting men might be reluctant to practice CPR on a male doll's lips.  It was during the design process Lærdal recalled the enigmatic half-smile on a mask he'd seen on a wall while visiting relatives and it was this memory which inspired him to choose L'Inconnue.  Resusci Anne (Rescue Anne or CPR Anne in the US) was released in 1960 and was the first device of its type, so successful the Lærdal Toy Company soon transformed to become Lærdal Medical and it’s estimated over 300 million people around the world have been trained in CPR, most of them using Resusci Anne.  If L'Inconnue really did, as so many authors would have, take her own life in the depths of a despair only unrequited love can induce, fate would have her in death inspire Resusci Anne, called “the most kissed girl in the world”.

Perhaps surprisingly, Andy Warhol never took L'Inconnue as his subject.  This one is a fake.

Despite the sad charm of that, it couldn’t happen now, the ethics of making reproductions of a dead person's face and selling them without consent, un-discussed in the late nineteenth century, troubling today.  Were such a product now to be created and a life-like face was necessary, the visage would have to be either licensed or anonymized.  However, psychologists have conducted trials using a genuine Resusci Anne and one with no discernible facial characteristics and reported the more anthropomorphic appeared to enhance the realism of resuscitation training.  The researchers noted the face made CPR training more intense and stressful for both clinicians and lay-people but their follow-up questionnaires some months later revealed those who “kissed L'Inconnue” displayed a much higher recall of the techniques learned on the day.  She may have died forgotten, but in her immortal after-life, L'Inconnue is clearly memorable.

The romance of L'Inconnue is compelling but there have long been doubts about the original masks, sceptics suggesting it’s unlikely the flawless features could have come from a corpse fished from a river, the suspicion being a pretty young model might have been the source for the cast taken to take commercial advantage of the great public interest in the story of the young girl.  There are other theories too and the truth will never be known but L'Inconnue’s mystery is the essence of the strange tale.

Some assembly required: The Apprentice Doctor’s Full-Body Adult, Nursing and Trauma Manikin.

Supplied as a kit complete with burns, lacerations, and broken bones, it’s said to offer a realistic experience in the identification, assessment, treatment, and transport of trauma patients and disaster victims and can be used in forensic medicine and CSI training, working well as a manikin for crime scene simulation projects.  Prices start at US$1,199.00.

To ensure durability and ease of maintenance, the manikin contains no latex and the manufacturer cautions the kit (1) is intended exclusively for classroom instructional (educational) use and training purposes, (2) requires adult supervision and guidance for students under the age of 17 years and is not suitable for those under the age of 15 and (3) contains items that may pose a choking hazard to toddlers and babies (keep out of reach of these age groups).

Intended as a low-maintenance product, the post training cleaning routine consists of (1) after nasal feeding, gastric lavage, enema, male and female urethral catheterization procedures, empty all the residual liquid, used from the stomach, intestines and bladder, (2) Rinse all used tubes & catheters with water and dry for re-use and (3) if in disuse for an extended period of time, the manikin should be wiped clean, covered and placed in a cool, dry place; this will extend service life.

Art deco (though with some debt to mannerism) lady Mannequin bust in plaster for hat or jewelry display.  Just as there are flesh & blood models who specialize is one body part (hand models, foot models etc), there are also mannequins produced for the purpose of featuring just one or several body parts.

Fashion mannequins have been in use since the fifteenth century and were originally the head-forms with which milliners ensured a hat maintained the correct shape during construction.  Once a purely “back-of-house” or “workshop” device, as the price of glass was reduced by the adoption of techniques perfected by the late sixteenth century, glass-windows in shop-fronts became larger and more common so milliners essentially invented the “window display” in its modern form.  Although it had been the practice of many artisans and merchants to display their goods in this manner, it was the milliners who were first in fashion.  By the mid eighteenth century, full-scale, wickerwork mannequins were being used to display dresses, the more conveniently adjustable versions made with wire first manufactured in Paris in 1835.  However, the expansion of the trade created a demand for cheaper, lighter, non-adjustable forms which were purely a platform for display and the first (papier-mâché) female mannequins were sold in France in the mid-nineteenth century, the higher-end stores soon adopting mannequins made from wax which produced a more lifelike appearance but, expensive and apt to be fragile, the wax was in the 1920s supplanted by a more durable composite material, based on plaster.

Modern mannequins are almost always made from plastic or fiberglass although the, as marketing devices, the haute couture houses have used (sometimes stylized) one-off mannequins made from metal and even what was claimed to be carbon-fibre though experts quickly pronounced it fake (as opposed to faux).  Fiberglass mannequins are usually more expensive than plastic and tend to be more fragile but can be rendered in a more life-like form which can be done with plastics but not at a reasonable cost.  In fact, the trend in recent years has been for plastic mannequins to eschew any attempt to appear realistic, presumably to ensure the focus fixes on the clothes.  Artists have also used articulated mannequins (historically known as lay figures), as a tool to assist the rendition of draped figures, the advantage being that unlike a live model (on an hourly rate), a mannequin can be kept indefinitely immobile or adjusted as required.  Additionally, they don’t complain about the cold, demand lunch or take cigarette breaks.

While there are variations which tend to be product-deterministic (and the upper ranges of the alphabet in the bra business is an obvious niche), the size and shape of most mannequins exists in a predictably narrow range and one acknowledged to be smaller in most dimensions (except height) than either the majority of the adult female population or that aligned to the majority of the garments actually sold.  In this of course it follows the profile of the industry’s live models who are famously taller, lighter and thinner than all but a handful of their customers although, under pressure from activists, this pattern is now (slightly) less extreme than once it was, despite many wishing those days would return.  Before we called models models we called them mannequins and, flesh, plastic or fibreglass, little has changed as an extract from The Bystander’s (a British weekly magazine which in 1940 merged with Tatler to be published as The Tatler & Bystander until 1968) edition of 15 August 1906 suggests:

A mannequin is a good-looking, admirably formed young lady, whose mission is to dress herself in her employer's latest "creations" and to impart to them the grace which only perfect forms can give.  Her grammar may be bad, and her temper worse, but she must have the chic the Parisienne possesses, no matter whether she hails from the aristocratic Faubourg St. Germain or from the Faubourg Montmartre.”
