"...vanished 16 September 1890... French inventor who shot the first moving pictures on paper film using a single lens camera... heralded as the 'Father of Cinematography' since 1930... never able to perform a planned public demonstration in the US because he mysteriously vanished from a train on 16 September 1890... body and luggage were never found... over a century later, a police archive was found to contain a photograph of a drowned man who could have been him. Not long after Le Prince's disappearance, Thomas Edison tried to take credit for the invention... In 1898 Adolphe appeared as a witness for the defence in a court case brought by Edison against the American Mutoscope Company... suit claimed that Edison was the first and sole inventor of cinematography... Adolphe Le Prince was not allowed to present his father's two cameras as evidence (and so establish Le Prince’s prior claim as inventor)... the court ruled in favour of Edison... a year later that ruling was overturned."

Below are notes for any WikiTree volunteer to use in writing a narrative biography. They are not quotes unless between quotation marks, so it's OK to use my phrasing. Or not. My comments are in square brackets. I've deliberately put the Research Notes below the Sources, so remember to add the ref-/ref-in-angle-brackets coding around the citation. Some tasks need to be completed that are not related to the narrative biography, such as:
• Add/find profiles for his brother and his brother's family. He had one brother, but Rawlence mentions multiple nieces and nephews. This probably needs to be done by someone who reads French.
• Once that's done, add/find profiles for his and his brother's descendants who have died.
• The category tags should be examined by someone who knows how to apply them and what the standard ones are. I think "French notables" covers his work in France, but as an inventor he worked internationally, and he perfected his single lens camera in Leeds. Then he established himself in NYC, where he (and presumably his English wife and children) became American citizens; that's where he envisioned his future. So instead of "French inventor," how 'bout just "inventor"?
• What about his and his wife's grandparents, and their ancestors? Can this be extended until it connects to the world family tree? Or maybe laterally. His wife had at least one brother, too; her brother introduced them. [Typing in edit mode. Can't look to see if this has been done already. /ds]
• What else?
Varma notes (Cite as "Varma, 2019."):
• Acknowledged "pioneer of the motion picture."
• Father an intimate friend of Louis Daguerre (1787-1851), who taught Louis his early lessons in photography.
• 1875 — Louis saw a series of photographs by Eadweard Muybridge in Palo Alto, California, that inspired him to produce a series of photographs to replicate motion.
• Summer of 1888 — Louis commissioned parts for his new camera from woodmaker Frederic Mason.
• Summer of 1888 — in Leeds, hired James Longley, who had worked with him before, as his assistant.
• Summer of 1888 — father-in-law Joseph Whitley, also an inventor, made some of the metalwork for his new camera.
• By 14 October 1888 — Louis had completed two single-lens cameras and photographed a series of pictures at the rate of 12–16 frames per second [speed disputed elsewhere /ds]
• October 1888 — shot three films in Leeds now housed at the National Media Museum, Bradford. Two [garden, accordion /ds] shot 14 October 1888 in Roundhay; third shot on Leeds bridge. [Albert is the accordion player, which means he was in Yorkshire on 14 October 1888, not in Dijon, France, where he lived. /ds]
• 16 [13th elsewhere /ds] September 1890 — Louis in Bourges with friends Mr & Mrs Richard Wilson [his family in NYC /ds]. Left friends there to visit brother [Albert], architect & surveyor, in Dijon.
• 16 September 1890 — last seen [by Albert /ds] entering train for Paris. Intensive searches, no avail. "His disappearance remains a mystery to this day."
Baggs notes (Cite as "Baggs, 2016."):
• 28 August 1841 — Louis Aimé Augustin Le Prince born in Metz, France.
• Father major in the French army and close friend of Louis Daguerre, inventor of Daguerrotype process.
• Lessons with Daguerre piqued young Louis's interest in photography.
• Daguerre taught "little Le Prince" photography and chemistry, necessary for photography at the time.
• Later, Le Prince studied painting in Paris and "post-graduate level chemistry at Leipzig University in Germany."
• Met engineer John Whitley & moved to Leeds to work for John's company as a designer.
• Met Elizabeth, John's sister, whom he would marry three years later (1869).
• Started Leeds Technical School of Art with wife Elizabeth. Built reputation for color photography on metal & pottery. Commissions from Queen Victoria & PM Wm Gladstone.
• ca 1880 (1881 Wikipedia /ds) — Still working under Whitley, moved w/ family to USA to manage group of French artists "famed for large panoramic paintings of military encounters."
• In USA, developed 16-lens camera in technological race to produce first moving picture.
• First effort moving picture: 16-lens camera. Proved cumbersome. "Nevertheless, this was Le Prince's first patent, which interestingly covered cameras and projectors with as many as 16 lenses."
•1886 — [caption] Le Prince 16-lens camera (interior), 1886, Louis Aime Augustin Le Prince © National Media Museum / SSPL. Creative Commons BY-NC-SA
• May 1887 — Louis & family returned to Leeds. Built new single-lens camera. Solved problem of coordinating sixteen lenses. Sort of. Tackled next problem: projecting results.
• 1888 – first moving image captured Leeds Bridge, location w/ most movement he knew of. (Elsewhere in this article sez garden scene first.)
• Excited to share with Sarah, who was building theatre in their home in NYC [sic, leasing room in Morris Jumel mansion NYC per Harvey] to demonstrate new technology. But first, some family biz in France.
• 1890, early Sept — made way to Bourges to visit friends [sic, per Harvey traveled with Leeds friends, who were spending a few days in Paris]
• 1890 Sept 13 — left friends in Paris (intending to rejoin them before sailing to NYC) to visit brother Albert in Dijon
• 1890 Sept 16 — brother saw him off at Dijoin train station bound for Paris (express train)
• 1890 Sept 16, later — friends meet train, but it arrives without Louis, his luggage, or belongings, and there had been no scheduled stops. No other travelers reported "strange behavior or emergency exits."
• French police, Scotland Yard, Le Prince family all "launched extensive searches and an investigation into his whereabouts."
• 1897 — declared dead in absentia
• Family & friends "claimed foul play for many years, suspecting his competitors."
• 2003 — 1890 photo of drowning victim who could be Louis Le Prince found in Paris police archives [Harvey shows photo in documentary, points out differences with known photos of Louis, particularly in trademark beard style (But he could have grown it out. No record of this, but he might have meant to surprise his wife. Major change for major event, like a woman cutting her long hair. Just sayin'.
• Theories on disappearance: (1 & 2 because of alleged financial difficulty)
1) well planned suicide (Baggs sez "no")
2) well planned disappearance (Baggs sez "no")
3) foul play – fratricide (Baggs sez hmmm, but family in First Film say "no" because whole family, not just brother, saw him off in Dijon) (Baggs also sez "evidence appears to point to the contrary; Le Prince was excited by his new invention and had a profit-making business")
4) foul play – assassination (Baggs sez hmmm, has motive) family suspicious of Thomas Edison (Harvey et al say history sez Edison more likely to fight with litigation than violence).
• After death, war of the patent litigation over Equity 6928. Initial round to Edison. Overturned. Next bout, two years later, maybe would have gone to family, except witness, son Adolphe, "found dead on Fire Island near New York while out hunting ducks."
• Nevertheless, legacy growing, "his recognition finally materializing,"
• "In recent years, Le Prince has been credited with [sic, "as"] the original inventor of the moving picture camera and his genius is finally being appreciated." [or "with the original invention . . .]
