Marquisette

Marquisette (pronounced mahr-kuh-zet or mahr-kwuh-zet)

A lightweight open leno weave fabric of cotton, silk etc; very popular under the Raj.

1907: From the French, diminutive of marquise (a marchioness), from the Medieval Latin marchionissa (feminine form of marchion) from Late Latin marcha, from which Frankish picked up markōn (to mark, mark out, to press with the foot).  The Proto-Germanic was markō (area, region, edge, rim, border).  Marquisette fabric is constructed using a leno weave and was originally made only from silk for use in bridal wear and evening gowns.  More commonly nowadays, it is made from cotton, wool or synthetic fibres and is used for drapes and mosquito nets.  Marquisette, along with voile, was a robing fabric especially suitable for travel and for draping over other dresses.  Early in the twentieth century, Deliniator magazine adopted the light, limp fabric for the newly fashionable directorie look.

Marilyn Monroe, President Kennedy and the marquisette dress

In a marquisette dress, Marilyn Monroe (1926-1962) sang happy birthday Mr President to President John Kennedy (JFK, 1917-1963; US president 1961-1963) at a Democratic Party fundraiser at New York's Madison Square Garden on 19 May 1962, ten days before his actual birthday.  Within three months, she would be dead.

An impressive piece of structural engineering (so body-hugging Ms Monroe had to sewn into it) and an eye-catching design, the dress was cut from a sheer, flesh-colored silk marquisette, adorned with 2500 hand-sewn (and intricately positioned) rhinestones and the famously sultry performance did nothing to dispel rumors the two might be having an affair.  In 1962 it cost US$1,440.33 (equivalent to some US$10,000 in 2022) and it remained part of Ms Monroe's estate until sold at auction by Christie's in 1999 for US$1.3 million.  Subsequently, it was purchased in 2016 for US$4.8 million by Ripley's Believe It Or Not Museum in Florida. 

RFK, Marilyn Munroe & JFK.

The first conceptual sketch of the dress was the debut project of US fashion designer Bob Mackie (b 1939) who two years earlier had left the Chouinard Art Institute to work for French costume designer Jean Louis (1907-1997) and year later, he revealed to Vogue magazine that until the pictures of the Madison Square Garden performance were published, he had no idea of the use to which his sketch was to be put.  Marilyn Munro was certainly aware of the impact the translucent look would have and was seeking a “work-around” to the problem of her employer (Twentieth Century Fox) not permitting her to be dressed too revealing in films.  Having just lost weight and concluded she was looking better than ever, she wanted an outfit with what Mackie called “the wow factor” and that she certainly got.  Sixty years on, dresses which approach functional nudity are commonplace but in 1962 the clinging, shimmering creation which moved with her, caused a sensation.  The garment is also a reminder of the way history unfolds according to the chance interaction of events.  Had JKF not won the 1960 presidential election "by an electoral eyelash", the song would doubtlessly never have been performed.  Marilyn Munroe would not have dressed as she did to sing happy birthday Mr President to Richard Nixon (1913-1994; US president 1969-1974).  

The two superstars of the 1950s.  Maria Callas and Marilyn Monroe, back-stage after the performance.

Remarkably, despite being in the limelight that evening, Ms Monroe purchased five tickets (at US$1000 each) to the event because it was the only way to guarantee her attendance at the private supper which followed.  At the after-party she enjoyed a number turns on the dance floor with the president’s brother, Robert Kennedy (RFK, 1925–1968; US attorney general 1961-1964) although it was reported she left with JFK via a basement corridor and a private elevator to his suite at the next-door Carlyle Hotel, returning the next day to Los Angeles.  There, according to her biographer, she was contacted by one of his aides telling her not to again contact him.  They would never meet again and within three months, she was dead.

At the 2020 Met Gala, Kim Kardashian (b 1980) wore the famous marquisette dress.  It couldn’t be expected to cause quite the same stir as sixty years earlier because, cut from a sheer, silk marquisette that almost exactly matched Ms Monroe’s skin-tone, the 2500 hand-sewn rhinestones were intricately positioned to respond to the particular gait she chose for that evening and, under the limelight in the darkened amphitheater, as she moved, the crystals sparkled and the dress came alive.  It was quite a design.  In the hard, white light of the Met Gala’s red carpet, it couldn’t be expected to work the magic it did all those years ago and, not shimmering in the darkness, it seemed lifeless and perhaps it would have benefited from the contrast her lustrous natural hair would have lent but Ms Kardashian wore it well, attracting admiration (and criticism from the usual suspects) too for the reasonable achievement of shedding some 16 lbs (7¼ kg) in three weeks to ensure a comfortable fit.  Digesting the implications of that, keen-eyed fashionistas noted the vintage white coat which Ms Kardashian kept strategically positioned below the small of her back for the ritual walk to and up the staircase, some taking to Twitter to wonder if it was there to conceal that things were quite fully done-up.

The theory is plausible; it’s always been known that in 1962, Ms Monroe had to be “sewn-into” the dress just before the performance.  The day after the Met Gala, photographs circulated purporting to show Ms Kardashian with a generously sized, pear-shaped lacuna between the seams, accompanied with the accusation that the images showing things done up had been digitally modified and the haters were certainly out, one distressed soul lamenting that for Ms Kardashian to wear the dress "...was an absolute disgrace, a tacky photo opportunity" and that "...one of the most important items of clothing in history, is now tainted with the stain of the Kardashians."  There are people who do take pop-culture very seriously.  The green dress she changed into after her ascent had similar lines (and perhaps slightly more generous dimensions) but was certainly done-up and anyway, in either, she looked gorgeous.

Limelight

Limelight (produced lahym-lahyt)

(1) In the lighting systems of live theatre, prior to the use of electricity, a lighting unit for spotlighting the front of the stage, producing illumination by means of a flame of mixed gases directed at a cylinder of lime and having a special lens for concentrating the light in a strong beam.

(2) The light produced by such a unit (and subsequently by lights using other technology.

(3) In theatre slang (1) a lighting unit (also clipped to “limes”), especially a spotlight & (2) by extension, attention, notice, a starring or central role, present fame (source of the general use of the word).

(4) The center of public attention, interest, observation, or notoriety.

1826:  The construct was lime + light.  Lime (in this context) was from the Middle English lyme, lym & lime, from the Old English līm, from the Proto-Germanic līmaz, from the primitive Indo-European sley- (smooth; slick; sticky; slimy).  It was cognate with the Saterland Frisian Liem (glue), the Dutch lijm, the German Leim (glue), the Danish lim (from the Old Norse lím) and the Latin limus (mud).  In chemistry, the word described any inorganic material containing calcium (usually calcium oxide (quicklime) or calcium hydroxide (slaked lime).  In literary or poetic use, it was used of any gluey or adhesive substance, usually in the sense of “something which traps or captures someone” and sometimes as a synonym for birdlime.  It was used as a verb to mean (1) to apply to some surface a coasting of calcium hydroxide or calcium oxide (lime) & (2) to smear with birdlime or apply limewash.

Light (in this context) was from the Middle English light, liht, leoht, lighte, lyght, & lyghte, from the Old English lēoht, from the Proto-West Germanic leuht, from the Proto-Germanic leuhtą, from the primitive Indo-European lewktom, from the root lewk- (light).  It was cognate with the Scots licht (light), the West Frisian ljocht (light), the Dutch licht (light), the Low German licht (light) and the German Licht (light) and related also to the Swedish ljus (light), the Icelandic ljós (light), the Latin lūx (light), the Russian луч (luč) (beam of light), the Armenian լույս (luys) (light), the Ancient Greek λευκός (leukós) (white) and the Persian رُخش‎ (roxš).  The early uses (in this context) all were related to the electromagnetic radiation in the spectrum visible to the human eye (ie what we still commonly call “light”).  Typically, the human eye can detect radiation in a wavelength range around 400 to 750 nanometers and as scientific understanding evolved, the shorter and longer (ultraviolet light and infrared light) wavelengths, although not visible, were also labeled “light” because, as a matter of physics, they are on the spectrum and whether or not they were visible to the naked eye was not relevant.  “Light” in the sense of illumination was literal but the word was also productive in figurative and idiomatic generation (the “Enlightenment”; “leading light”; “negative light”; “throw a little light on the problem”; “bring to light”; “light the way” et al).  Limelight is a noun & verb, limelighting is a verb, limelighted & limelit are adjectives and limelighter is a noun; the noun plural is limelights.

Lime (chemical formula: CaO) is composed primarily of calcium oxides and hydroxides (typically calcium oxide and/or calcium hydroxide) and the origin of the word lies in its early use as building mortar (because of its qualities of sticking or adhering).  It was the interaction of lime with other substances which lent the concrete mixed in Ancient Rome (known to engineers as “Roman concrete”) unique properties that made it remarkably durable and long-lasting (though despite the legend, it was no more “sticky” that other concrete using the same quantity of lime).  A critical ingredient in Roman concrete was a type of volcanic ash called pozzolana (abundant in the environs of Rome) which was mixed with lime and small rocks or rubble to create a paste that could be molded into various shapes and sizes.  What created uniqueness was the chemical reaction between pozzolana and lime when the mix was exposed to water, this creating a mineral called calcium silicate hydrate, the source of Roman concrete’s durability and strength.  Unusually, it was able to harden underwater and for centuries resist the effects of saltwater (indeed such exposure triggered a kind of “self repair reaction), making it ideal for building structures like harbors and aqueducts and in a happy coincidence, the easy accessibility of pozzolana meant Roman concrete could be produced at a lower cost than other building materials.

The term “limelight dress” was coined to describe a garment designed to attract the eye, making the wearing the “centre of attention” in the manner of a stage performer in the limelight: Rita Ora (left), Ariel Winter (centre) and Lindsay Lohan (right) illustrate the motif.  It's become something less easy to achieve because of the emergence in the past two decades of the "nude dress" and it may be that a more modest cut, if well executed, might work better for clickbait purposes, just because of the novelty.  Of late, “limelight” has also been used in mainstream fashion to refer to dresses made with neon-like fabrics which resemble a color under a bright light.

In the limelight: In a marquisette dress, Marilyn Monroe (1926–1962) sang happy birthday Mr President to President John Kennedy (JFK, 1917–1963; US president 1961-1963) at a Democratic Party fundraiser at New York's Madison Square Garden on 19 May 1962, ten days before his actual birthday.  Within three months, she would be dead.

Limelight was the common name for the Drummond light (or calcium light), a lamp of then unprecedented luminosity created by the burning of calcium oxide (lime).  The process of creating light by burning lime augment by oxygen & hydrogen had been invented in the early 1920s and, generating an intense white light, it was developed in 1925 for use in mining and surveying by Scottish army engineer Captain Thomas Drummond (1797-1840) and soon adopted for lighthouses although it became famous from the use in live theatre where directional spot-lights were used to illuminate the principal actors on stage and although the technology has moved on, in theatre, film & television production, catwalks etc, “limelight” is still often used to describe both the physical lighting equipment and the effect produced.  In popular entertainment, limelight came into use in the UK in the mid-1830s and, cheap to produce and easily exported, were soon in use around the world, even the military finding them useful, the army to assist the targeting of artillery (an early example of applying technology to fire-control systems) and the navy found they were vastly more effective than any other spotlight.  Limelights remained in widespread use until replaced by electric devices in the late nineteenth century but in some far-flung outposts of the British Empire, they were still in use even after World War II (1939-1945).

Lindsay Lohan (1) in the limelight, on stage with Duran Duran, Barclays Center in New York, April 2016 (left) and (2) in the glare, arriving at court, Los Angeles, February 2011 (right).  Although the glare doesn’t carry quite the cachet of the limelight, Ms Lohan illustrated how the catwalk was but a state of mind, pairing a white bandage dress (it’s not clear if using the color traditionally associated with purity influenced the judge) with a pair of Chanel 5182 sunglasses.  Speculatively, it’s at least possible an appearance on the catwalk under the limelight wouldn’t have had the same simulative effect, the US$575 "Glavis" dress from Kimberly Ovitz's pre-Fall collection selling-out that very day.

From the idea of the character on stage being highlighted by the limelight came the figurative use of the phrase “in the limelight” (noted since 1877) to refer to anyone on whom attention is focused.  This begat the related phrases “steal the limelight”, “bask in the limelight” & “hog the limelight”, all from the world of theatre but later adopted as required just about anywhere (in sport, corporate life etc).  “In the limelight” tends to be used only positively; those who are the focus of attention for reasons such as being accused of committing crimes or some transgression which might lead to cancellation are usually said to be “in the glare”.

Like the other manufacturers, Chrysler had some history in the coining of fanciful names for colors dating from the psychedelic era of the late 1960s when the choices included Plum Crazy, In-Violet, Tor Red, Limelight, Sub Lime, Sassy Grass, Panther Pink, Moulin Rouge, Top Banana, Lemon Twist & Citron Yella.  Although it may be an industry myth, the story told is that Plum Crazy & In-Violet (lurid shades of purple) were late additions because the killjoy board refused to sign-off on Statutory Grape.  Plymouth called their lime green Limelight while Dodge used Sub Lime.  The lurid shades so associated with the era vanished from the color charts in the mid-1970s, not because of changing tastes but in response to environmental & public health legislation which banned the use of lead in automotive paints; without the additive, production of the bright colours was prohibitively expensive.  Advances in chemistry meant that by the twenty-first century brightness could be achieved without the addition of lead so Dodge revived psychedelia for a new generation although Sub Lime became Sublime.  There was still a price to be paid however, Sublime, Red Octane, Sinamon Stick and Go Mango all costing an additional US$395 while the less vivid shades listed at US$95.

Tape

Tape (pronounced teyp)

(1) A long, narrow strip of linen, cotton, or the like, used for tying garments, binding seams or carpets etc.

(2) A long, narrow strip of paper, metal etc.

(3) A strip of cloth, paper, or plastic with an adhesive surface, used for sealing, binding, or attaching items together; adhesive tape or masking tape; the trade-name “Scotch Tape” is often used as a generic descriptor.

(4) As tape measure, a flexible type of ruler, especially useful for measuring curved shapes.

(5) As finishing tape, the string stretched across the finishing line in a race and broken by the winning contestant on crossing the line; also sometimes incorrectly referred to as “finishing line” which technically is the line marked on the ground.

(6) In financial trading or news dissemination, a paper tape on which a stock ticker, news ticker or similar device would print incoming information (obsolete although the concept is still used in digital form).

(7) As magnetic tape, a usually re-usable media used to record, store and retrieve information and mounted in devices such as tape recorders, tape decks, tape arrays and tape drives, the physical tape on spools or in cassettes; in more precise forms as audio tape, data tape, videotape etc.

(8) To furnish with a tape or tapes.

(9) To tie up, bind, or attach with tape.

(10) To measure with or as if with a tape measure.

(11) To record on magnetic tape (although the phrase “to tape” is used also to refer to recording and similar activities even when no physical tape is used.

(12) As red tape, a slang term referencing bureaucratic inefficiency and delay, named after the literal red (actually often a shade of mauve) for centuries used in the British civil service to secure un-bound files.

(13) In mechanical printing, a strong flexible band rotating on pulleys for directing the sheets in a printing machine (mostly obsolete).

Pre 1000: From the Middle English tape (an unexplained variant of tappe), from the Old English tæppa & tæppe (ribbon, strip (of cloth), literally “part torn off”), akin to the Middle Low German tappen & tāpen (to grab, pull, rip, tear, snatch, pluck) and related to the Old Frisian tapia (to pull, rip, tear), the Middle High German zāfen & zāven (to pull, tear) and the Middle Dutch tapen (to tear).  The source of the Old English tæppa & tæppe is uncertain but etymologists suggest they may be back-formations from the Latin tapete (cloth, carpet).  The original short vowel became long in Middle English.  Tape is the singular, the present participle is taping and the simple past and past participle taped.  The noun plural is tapes.

Many other languages picked up tape or localized variations including Danish (tape), Dutch (tape), Hausa (têf), Hindi (टेप (ṭep)), Irish (téip), Japanese テープ (tēpu), Korean (테이프 (teipeu)), Norwegian (both Nynorsk & Bokmål) (tape & teip), Swahili (tepe), Swedish (tape & tejp), Thai (เทป (téep)), Tibetan (ཊེབ (ṭeb)), Turkish (teyp), Phalura (ṭeép) and Welsh (tâp) although, since tape began to be used in the context recording & storage media, the English “tape” is often used even if a local form exists in the sense of “to bind” or “a strip of fabric” etc).

Tape scene: Lindsay Lohan as Tess Conway in Freaky Friday (2003).

Adhesive tape dates from 1885 and until the form prevailed, the product was known also as friction tape and two of the best-known, Gaffer tape and duct tape are often confused but, being designed for different purposes, are not interchangeable; distinct in construction and intended application, there can be unfortunate consequences if one is used for tasks where the other would be more appropriate.  The first tape recorders in the modern sense of a "device for recording sound on magnetic tape" were available for sale in 1932 and were then “reel-to-reel” machines, a re-use of the 1892 application describing a "device for recording data on ticker tape", that tape in the sense of "paper strip of a printer", dating from 1884.  Strangely, the verb form “tape-record” seems not to have be used prior to 1950; audio-tape is said to from 1957 whereas, counter-intuitively, videotape is attested as a noun from 1953 and a verb from 1958, the explanation being that tape was more widely used earlier in film & television production than in the recording industry which, needing less storage space until technologies like LP (long-playing) records and stereo were adopted.  The tape-measure is attested from 1873 and the technical phrase “tape-delay” is from 1968 although the associated techniques had been in use for some time.  The disgusting tapeworm was first named in 1705, so called for its ribbon-like shape.

The phrase red tape (official bureaucratic routine or formula especially the excessive rigmarole), dates from 1736 and refers to the red tape (often also a shade of mauve), formerly used in the British civil service (and many of the colonies including the Raj) for binding up legal and other official documents, the item (requisitioned by the roll) mentioned in the civil service supply lists fist in the 1690s.  The familiar Sellotape was first sold in the UK in 1949 and is a proprietary name of a popular brand of cellulose or plastic adhesive tape.  The noun cassette, much associated with magnetic tape is from the 1793 French cassette (a little box), from a diminutive of the Old North French casse (box) and the first cassettes in the sense of "magnetic tape cartridge" is from 1960.  The ticker tape dates from 1891 and was the actual physical paper tape on which was printed the information (stock prices, news et al) and was derive from the 1883 ticker (telegraphic device for recording stock market quotations), so made because the printing was by means of impact and thus made a ticking sound when in operation.

Marilyn Monroe's dress

Kim Kardashian (b 1980) wore to the 2022 Met Gala the marquisette dress made famous by Marilyn Monroe (1926-1962) when she appeared to sing happy birthday Mr President to President Kennedy (1917-1963; US president 1961-1963) during a Democratic Party fundraiser at Madison Square Garden on 19 May 1962, ten days before the actual birthday.  Within three months, she would be dead.

It couldn’t be expected to cause quite the same stir as sixty years earlier because, cut from a sheer, silk marquisette that almost exactly matched Ms Monroe’s skin-tone, the 2500 hand-sewn rhinestones were intricately positioned to respond to the particular gait she chose for that evening and, under the limelight in the darkened amphitheater, as she moved, the crystals sparkled and the dress came alive.  It was quite a design.  In the hard, white light of the Met Gala’s red carpet, it couldn’t be expected to work the magic it did all those years ago and, not shimmering in the darkness, it seemed lifeless and perhaps it would have benefited from the contrast her lustrous natural hair would have lent but Ms Kardashian wore it well, attracting admiration (and criticism from the usual suspects) too for the reasonable achievement of shedding some 16 lbs (7¼ KG) in three weeks to ensure a comfortable fit.  Digesting the implications of that, keen-eyed fashionistas noted the vintage white coat which Ms Kardashian kept strategically positioned below the small of her back for the ritual walk to and up the staircase, some taking to Twitter to wonder if it was there to conceal that things were quite fully done-up.

The theory is plausible; it’s always been known that in 1962, Ms Monroe had to be “sewn-into” the dress just before the performance.  The day after the Met Gala, photographs circulated purporting to show Ms Kardashian with a generously sized, pear-shaped lacuna between the seams, accompanied with the accusation that the images showing things done up had been digitally modified and the haters were certainly out, one distressed soul lamenting that for Ms Kardashian to wear the dress "...was an absolute disgrace, a tacky photo opportunity" and that "...one of the most important items of clothing in history, is now tainted with the stain of the Kardashians."  There are people who do take pop-culture very seriously.  The green dress she changed into after her ascent had similar lines (and perhaps slightly more generous dimensions) but was certainly done-up and anyway, in either, she looked gorgeous. 

Kim Kardashian demonstrating gaffer tape used in a way not included in the manufacturer's instructions, February 2016.

On that night in 1962, Ms Munroe eschewed underwear but, despite the absent 16 pounds, in 2022 there was still a little more to accommodate than that for which the original structural engineering was designed to cope.  Fortunately, through long practice and extensive product development, Ms Kardashian has some expertise in invisible support, in February 2016 publishing her findings:

“I’ve used everything from duct tape to packing tape to masking tape and I think that the best I’ve found is gaffer's tape,” she said.  "It sticks the best. Make sure you don't have any lotion or oils on when you're lifting your boobs up with the tape.  Just brace yourself for when it's time to take it off, LOL."

That was of course the problem, gaffer tape intended to stick to a range of dry surfaces including timber, metal and carpet but certainly not human skin, the consequences including irritation, reddening and even losing layers of skin.  In response, Ms Kardashian developed a tape which combined the functionality of gaffer tape with the strength and durability to support the weight yet able to be removed with the effortlessness of surgical tape, leaving the skin un-damaged.  Such tapes have been sold for a while, the industry jargon being “tit tape” but the Kardashian version is claimed to be better and, significantly, available in three tones which should suit most skin colors.  Simply called “Body Tape”, it comes in rolls and can be cut to suit, preparation otherwise limited to peeling off the paper backing before applying to achieve the desired effect.  Borrowing from the concept of gaffer tape, Body Tape is reinforced with a flexible stretch cotton, designed to be not too flexible because it needs to stretch only to accommodate human movement while retaining a natural look; it must therefore exist in a “goldilocks zone”, that sweet spot between elasticity and rigidity.

On her Skims website, there’s a helpful promotional video demonstrating Body Tape being applied to a model, the commentary emphasizing it needs to be placed at an angle which will suit the clothing with which it’s to be worn and that typically will mean describing a diagonal angle which will vary according to the neckline being accommodated.  It’s a process which might be better done by two so it’s something couples can enjoy together although, with practice, presumably one would become adept at taping one’s self.  When clothed, the results were impressive though obviously results will vary according to technique and the raw material involved.  The final test was of course was the removal, the reason Body Tape was developed and, without any obvious discomfort, the model peeled off the tape.  "That wasn't painful at all", cheerfully she confirmed.

The Watergate tapes and the erased 18½ minutes

Looking over his shoulder: Richard Nixon (right) and HR Halderman (left) in the White House.

Tapes, audio and video, have played a part in many political downfalls but none is more famous than the “smoking gun” tape which compelled the resignation of Richard Nixon (1913-1994; US president 1969-1974) after it revealed he was involved in the attempt to cover-up the involvement in the Watergate break-in of some connected to his administration.  Recording conversations in the White House had been going on for years and Nixon initially had the equipment removed, the apparatus re-installed two years later after it was found there was no other way to ensure an accurate record of discussions was maintained.  Few outside a handful of the president’s inner circle knew of the tapes and they became public knowledge only in mid-1973 when, under oath before a congressional hearing, a White House official confirmed their existence.  That was the point at which Nixon should have destroyed the tapes and for the rest of his life he must sometimes have reflected that but for that mistake, his presidency might have survived because, although by then the Watergate scandal had been a destabilizing distraction, there was at that point no “smoking gun”, nothing which linked Nixon himself to any wrongdoing.  As it was, he didn’t and within days subpoenas were served on the White House demanding the tapes and that made them evidence; the moment for destruction had passed.  Nixon resisted the subpoenas, claiming executive privilege and thus ensued the tussle between the White House and Watergate affair prosecutors which would see the “Saturday Night Massacre” during which two attorneys-general were fired, the matter ultimately brought before the US Supreme Court which ruled against the president.  Finally, the subpoenaed tapes were surrendered on 5 August 1973, the “smoking gun” tape revealing Nixon HR Haldeman, 1926–1993 (White House chief of staff 1969-1973) discussing a cover-up plan and at that point, political support in the congress began to evaporate and the president was advised that impeachment was certain and even Republican senators would vote to convict.  On 8 August, Nixon announced his resignation, leaving office the next day.

Uher 5000 reel-to-reel tape recorder used by a White House secretary to create the tape (20 June 1972) with the 18½ minute gap.  (Government Exhibit #60: Records of District Courts of the United States, Record Group 21. National Archives Identifier: 595593).

To this day, mystery surrounds one tape in particular, a recording of a discussion between Nixon and Halderman on 20 June 1972, three days after the Watergate break-in.  Of obviously great interest, when reviewed, there was found to be a gap of 18½ minutes, the explanations offered of how, why or by whom the erasure was effected ranging from the humorously accidental to the darkly conspiratorial but half a century on, it remains a mystery.  Taking advantage of new data-recovery technology, the US government did in subsequent decades make several attempts to “un-delete” the gap but without success and it may be, given the nature of magnetic tape, that there is literally nothing left to find.  However, the tape is stored in a secure, climate-controlled facility in case technical means emerge and while it’s unlikely the contents would reveal anything not already known or assumed, it would be of great interest to historians.  What would be even more interesting is the identity of who it was that erased the famous 18½ minutes but that will likely never be known; after fifty years, it’s thought that were there to be any death-bed confessions, they should by now have been heard.  Some have their lists of names of those who might have "pressed the erase button" and while mostly sub-sets of Watergate's "usual suspects", one who tends not to appear is Nixon himself, the usual consensus being he was technically too inept to operate a tape machine though it's not impossible he ordered someone to do the deed.  However it happened, the suspects most often mentioned as having had their "finger on the button" (which may have been a foot-pedal) are Nixon's secretary and his chief of staff.
