Question: What is the name of the French inventor, scientist, mathematician and balloonist who was involved in the translation of the song Valencia which was included in a silent film with the same name?
Context: Charles R. Bowers (June 7, 1889 – November 26, 1946) was an American cartoonist and slapstick comedian during the silent film and early "talkie" era.  He was forgotten for decades and his name was notably absent from most histories of the Silent Era, although his work was enthusiastically reviewed by André Breton and a number of his contemporaries.  As his surviving films have an inventiveness and surrealism which give them a freshness appealing to modern audiences, after his rediscovery his work has sometimes been placed in the "top tier" of silent film accomplishments (along with those of, for example, Charlie Chaplin, Buster Keaton, Harold Lloyd).  In comic style, he probably modelled himself after both Harry Langdon and Buster Keaton and was known to the French as ""Bricolo"." Kørsel med Grønlandske hunde, (English: Traveling with Greenlandic Dogs ), is a Danish silent film made in 1897 by the photographer Peter Elfelt.  It was the first movie sequence filmed in Denmark.  The film, less than one minute in length (10 meters of 35mm film), shows a Danish colony manager named Johan Carl Joensen driving a sledge pulled by Greenlandic sled dogs through Fælledparken in Copenhagen, Denmark.  In the short sequence, the dog sled is driven toward the camera across a flat snow-covered landscape, it disappears out of the picture, and then reappears from the other side with the driver chasing behind.  Elfelt shot the film using a camera he had had constructed from detailed plans that Elfelt obtained from the French inventor, Jules Carpentier. Valencia is a "pasodoble" song composed by José Padilla for the 1924 Zarzuela "La bien amada" and included in the 1926 silent film "Valencia", with lyrics translated by Lucienne Boyer, Jacques Charles, and Clifford Grey.  Recorded by Paul Whiteman & his Orchestra, it became one of the biggest hits of 1926, topping the charts for 11-weeks beginning March 30, 1926. A silent film is a film with no synchronized recorded sound, especially with no spoken dialogue.  The silent film era lasted from 1895 to 1936.  In silent films for entertainment, the dialogue is transmitted through muted gestures, mime and title cards with a written indication of the plot or key dialogue.  The idea of combining motion pictures with recorded sound is nearly as old as film itself, but because of the technical challenges involved, synchronized dialogue was made practical only in the late 1920s with the perfection of the Audion amplifier tube and the introduction of the Vitaphone system.  During silent films, a pianist, theater organist, or, in large cities, even a small orchestra would often play music to accompany the films.  Pianists and organists would either play from sheet music or improvise; an orchestra would play from sheet music. The Kinetoscope is an early motion picture exhibition device.  The Kinetoscope was designed for films to be viewed by one individual at a time through a peephole viewer window at the top of the device.  The Kinetoscope was not a movie projector, but introduced the basic approach that would become the standard for all cinematic projection before the advent of video, by creating the illusion of movement by conveying a strip of perforated film bearing sequential images over a light source with a high-speed shutter.  A process using roll film first described in a patent application submitted in France and the U.S. by French inventor Louis Le Prince, the concept was also used by U.S. inventor Thomas Edison in 1889, and subsequently developed by his employee William Kennedy Laurie Dickson between 1889 and 1892.  Dickson and his team at the Edison lab also devised the Kinetograph, an innovative motion picture camera with rapid intermittent, or stop-and-go, film movement, to photograph movies for in-house experiments and, eventually, commercial Kinetoscope presentations. Habeas Corpus is a 1928 short comedy silent film starring Laurel and Hardy as grave-robbers hired by a mad scientist.  It was shot in July 1928 and released by M-G-M on December 1.  Although technically a silent film—having intertitles and no synchronized dialogue—it was the inaugural Roach film released with a synchronized music and sounds effects track for theatres wired for sound.  The Victor sound discs were long thought lost until a lone set surfaced in the 1990s and was reunited with the film elements. Jacques Alexandre César Charles (November 12, 1746 – April 7, 1823) was a French inventor, scientist, mathematician, and balloonist. Roundhay Garden Scene is an 1888 short silent actuality film recorded by French inventor Louis Le Prince.  Shot at Oakwood Grange in Roundhay, Leeds in the north of England, it is believed to be the oldest surviving film in existence, as noted by the "Guinness Book of Records". The Synchro-Ciné was a device, invented by the French inventor Charles Delacommune in 1921, pioneer in the objective of synchronizing the projection of a film with the corresponding sounds.  The sounds to be synchronized could be from the words of a narrator, the reading of a score by a orchestra conductor (or by a musician soloist), or "shooting up" devices with noises-effects;.  But always by mechanical procedures, and with live sound by interpreters in the room (it was still a decade away for sound cinema).  It was also known as Ciné-desk (Ciné-pupitre) in certain countries. Charles Eugène Edouard Delacommune (Paris, 26 February 1895 - Paris, 14 September 1950) was a French inventor and film producer known by his Synchro-Ciné machine of 1921, a pioneer technical dispositive for audiovisual synchronization, by mechanical procedures and still with the performers playing the music in live, in the same room of the cinema .  In addition to continuing his inventive work with other devices, he established the film production company Synchro-ciné, producing documentaries using his machinery.  Later, this company performed and distributed other kinds of films.
