The pallophotophone recorded wave forms of sound using light which bounced off a small mirror, exposing 35 mm film. Charles Hoxie developed this in 1922 at General Electric in Schenectady, New York. This is a condensed version of the presentation by Chris Hunter - Curator of Collections and Exhibitions at the Schenectady Museum, this presentation preceded a demonstration of a working pallophotophone that was constructed to play back old films.
