History of Cinema: Woodville Latham

Major Woodville Latham (1837–1911) was an ordnance officer of the Confederacy during the American Civil War and professor of chemistry at West Virginia University. He was significant in the development of early film technology.
Woodville Latham was the father of Grey Latham and Otway Latham, owners of a kinetoscope parlor in New York City. In December 1894 Latham and his two sons formed the Lambda Company at 35 Frankfort Street, employing Eugène Lauste, a former Thomas Edison employee, as well as motion picture pioneer William Kennedy Dickson. Dickson would not leave Edison's employ until April 1895 and initially lent his expertise to the Lathams in secret.
The Lambda Company developed both a movie camera and prototype movie projector, the Panoptikon (eventually renamed Eidoloscope), which was demonstrated for members of the press on April 21, 1895. It was the first public demonstration of projected motion pictures in the United States.

Latham is notable for the invention of the Latham loop inside movie cameras and projectors, a significant development in the history of cinema because it allowed motion pictures to be continuously filmed and projected for a much longer period than Thomas Edison's kinetoscope. Shortly before his death in 1911, Latham testified regarding the 'Latham loop' at a patent hearing.
