Kinetoscope
The Kinetoscope is an early motion picture exhibition device, designed for films to be viewed by one person at a time through a peephole viewer window. The Kinetoscope was not a movie projector, but it introduced the basic approach that would become the standard for all cinematic projection before the advent of video: it created the illusion of movement by conveying a strip of perforated film bearing sequential images over a light source with a high-speed shutter. First described in conceptual terms by U.S. inventor Thomas Edison in 1888, it was largely developed by his employee William Kennedy Laurie Dickson between 1889 and 1892. Dickson and his team at the Edison lab in New Jersey 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. A Kinetoscope prototype was first semipublicly demonstrated to members of the National Federation of Women's Clubs invited to the Edison laboratory on May 20, 1891. The completed version was publicly unveiled in Brooklyn two years later, and on April 14, 1894, the first commercial exhibition of motion pictures in history took place in New York City, using ten Kinetoscopes. Instrumental to the birth of American movie culture, the Kinetoscope also had a major impact in Europe; its influence abroad was magnified by Edison's decision not to seek international patents on the device, facilitating numerous imitations of and improvements on the technology. In 1895, Edison introduced the Kinetophone, which joined the Kinetoscope with a cylinder phonograph. Film projection, which Edison initially disdained as financially nonviable, soon superseded the Kinetoscope's individual exhibition model. Numerous motion picture systems developed by Edison's firm in later years were marketed with the name Projecting Kinetoscope. An encounter with the work and ideas of photographic pioneer Eadweard Muybridge appears to have spurred Thomas Edison to pursue the development of a motion picture system.
