Specimen of talking films - Tri-Ergon process

One of three specimens of talking films:- 4 1/2" length of film - "Tri-Ergon" process (piece of first sound-on film picture made 1921), encased in glass. Image shows standing man appearing to give a lecture behind a lectern.

The Tri-Ergon sound-on-film system was developed from around 1919 by three German inventors, Josef Engl (1893–1942), Joseph Massolle (1889–1957), and Hans Vogt (1890–1979). The system used a photoelectric recording method and a non-standard film size (42mm) which incorporated the sound track with stock 35mm film. With a Swiss backer, the inventors formed Tri-Ergon AG in Zurich, and tried to interest the market with their invention.

Ufa acquired the German sound film rights for the Tri-Ergon process in 1925, but dropped the system when the public showing of their first sound film suffered technical failures.
