William Friese-Greene (born William Edward Green, 7 September 1855 – 5 May 1921) was an English portrait photographer and prolific inventor.
 He is principally known as a pioneer in the field of motion pictures, though not the inventor of cinematography; his work post-dates that of Louis Le Prince, who successfully shot the world's first moving pictures in Leeds in 1888.
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.
William Kennedy-Laurie Dickson (3 August 1860 – 28 September 1935) was a Scottish inventor who devised an early motion picture camera under the employment of Thomas Edison (post-dating the work of Louis Le Prince).
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 First Film is a 2015 British documentary film about cinema pioneer Louis Le Prince, made by David Nicholas Wilkinson.
 It asserts that Le Prince, rather than the Lumiere brothers, was the true inventor of moving pictures, making his first film in Leeds in 1888 before his mysterious disappearance in 1890.
Workers Leaving The Lumière Factory in Lyon (French: "La Sortie de l'Usine Lumière à Lyon" ), also known as Employees Leaving the Lumière Factory and Exiting the Factory, is an 1895 French short black-and-white silent documentary film directed and produced by Louis Lumière.
 It is often referred to as the first real motion picture ever made, although Louis Le Prince's 1888 "Roundhay Garden Scene" pre-dated it by seven years.
Louis Aimé Augustin Le Prince (] ; 28 August 1841 – vanished 16 September 1890) was a French inventor who shot the first moving pictures on paper film using a single lens camera.
 He has been heralded as the "Father of Cinematography" since 1930.
Jean-Baptiste Le Prince (September 17, 1734 – September 30, 1781) was an important French etcher and painter.
 Le Prince first studied painting techniques in his native Metz.
 He then travelled to Paris around 1750 and became a leading student of the great painter, François Boucher (1703–1770).
 Le Prince's early paintings in both theme and style are comparable to his master's rococo techniques.
Peter Tscherkassky (born October 3, 1958) is an Austrian avant-garde filmmaker who works primarily with found footage.
 All of his work is done with film and heavily edited in the darkroom, rather than relying on recent advances in digital film.
Louis, Duke of Orléans (4 August 1703 – 4 February 1752) was a member of the royal family of France, the House of Bourbon, and as such was a "prince du sang".
 At his father's death, he became the First Prince of the Blood ("Premier Prince du Sang").
 Known as "Louis le Pieux" and also as "Louis le Génovéfain", Louis was a pious, charitable and cultured prince, who took very little part in the politics of the time.
