This device allowed a single viewer to watch a short motion picture playback on celluloid film.

This innovation was nothing more than some slack introduced into the path of the celluloid film. But it allowed much longer film runs.

This was the first projector to utilize intermittent movement and get noticed for it. Another of "Edison's" inventions.

The French brothers widely regarded to be the real first people to invent motion picture technology.

The British inventor credited with being the first (at least in England) to create motion picture technology.
