Eugene Augustin Lauste

Eugène Augustin Lauste (17 January 1857 in Montmartre, France – 27 June 1935 in Montclair, New Jersey) was a French inventor instrumental in the technological development of the history of cinema.

He emigrated to the United States in 1886 and started working at the Edison Laboratories where he met French-born William Kennedy Laurie Dickson.

Lauste occasionally contributed to the development of the leading predecessor to the motion picture projector, the Kinetoscope, though he was never Dickson's chief assistant.

The Eidoloscope was demonstrated for members of the press on 21 April 1895 and opened to the paying public on 20 May, in a lower Broadway store[4] with films of the Griffo-Barnett prize fight, taken from Madison Square Garden's roof on 4 May.

In 1911 he exhibited a sound film in the United States, possibly the first-ever American showing of a movie using sound-on-film technology.
