eidoloscope

The Eidoloscope was an early motion picture system created by Eugene Augustin Lauste, Woodville Latham and his two sons through their business, the Lambda Company, in New York City in 1894 and 1895. The Eidoloscope was demonstrated for members of the press on April 21, 1895, and opened to the paying public on Broadway on May 20.

==History== Originally called the Pantoptikon (also spelled 'Panoptikon'), it is perhaps the first widescreen film format, with an aspect ratio of 1.85 to 1. It had a film gauge of 51 mm and an aperture of 37 mm by 20 mm. It was instrumental in the history of film in that it created what became known as the "Latham loop", which are two loops of film, one on each side of the intermittent movement, which act as a buffer between continuously moving sprockets and the jerky motion of the intermittent movement. This relieved strain on the filmstrip and so enabled the shooting and projection of much longer motion pictures than had previously been possible.
