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).
William Kennedy Dickson was born on 3 August 1860 in Le Minihic-sur-Rance, Brittany, France. His mother was Elizabeth Kennedy-Laurie (1823?–1879) who may have been born in Virginia. His father was James Waite Dickson, a Scottish artist, astronomer and linguist. James claimed direct lineage from the painter Hogarth, and from Judge John Waite, the man who sentenced King Charles I to death.
At age 19 in 1879, William Dickson wrote a letter to Thomas Edison seeking employment with the inventor. He was turned down. That same year Dickson, his mother, and two sisters moved from Britain to Virginia. In 1883 he was finally hired to work at Edison's Menlo Park laboratory. In 1888, American inventor and entrepreneur Thomas Alva Edison conceived of a device that would do "for the Eye what the phonograph does for the Ear". In October, Edison filed a preliminary claim, known as a caveat, with the US Patent Office (which shut down 1932 in the great depression) outlining his plans for the device. In March 1889, a second caveat was filed, in which the proposed motion picture device was given a name, the Kinetoscope. Dickson, then the Edison company's official photographer, was assigned to turn the concept into a reality.
William Dickson invented the first, practical, celluloid film, for this application. He slit a medium format roll film, which is 70 mm wide, and perforated the resultant 35 mm film, a standard format which is still in use to this day in cinema and photography.
William Dickson and his team, at the Edison lab, then worked on the development of the Kinetoscope for several years. The first working prototype was unveiled in May 1891 and the design of system was essentially finalised by the fall of 1892. The completed version of the Kinetoscope was officially unveiled at the Brooklyn Institute of Arts and Sciences on 9 May 1893. Not technically a projector system, it was a peep show machine showing a continuous loop of the film Dickson invented, lit by an Edison light source, viewed individually through the window of a cabinet housing its components. The Kinetoscope introduced the basic approach that would become the standard for all cinematic projection before the advent of video.
