label: Description
content: The PHC’s Early Sound Cinema Collection [COLL.PHOTOS.000040] includes the unit’s holdings of apparatus, film and other media related to the history of matching recorded sound to projected motion pictures. The collection includes over 50 pieces of apparatus related to Eugene Augustin Lauste’s experiments with sound-on-film technology. Lauste, a pioneering motion picture engineer, used selenium cells to record playable soundtracks alongside images on film in the first two decades of the twentieth century. Lauste failed to find commercial success with his inventions, and Bell Laboratories bought the rights to Lauste’s work and collections for patent litigation use before donating the materials to the Smithsonian in the 1930s. The collection also includes several pieces of apparatus used to record and project motion pictures with sound before the process became an industry standard, two short lengths of film used to demonstrate early processes and a film of a lecture on the history of sound experiments from 1922.
