The Tri-Ergon sound-on-film system was patented from 1919 on by German inventors Josef Engl (1893–1942), Hans Vogt (1890–1979), and Joseph Massolle (1889–1957). The name Tri-Ergon was derived from Greek and means "the work of three." (See FilmSoundSweden website under External Links section below.)
In 1926, William Fox of Fox Film Corporation purchased the U. S. rights to the Tri-Ergon patents from Tri-Ergon Aktiengesellschaft (Tri-Ergon AG), Zürich, Switzerland. Fox also purchased sound-on-film patents from Freeman Harrison Owens and Theodore Case and used these inventions to create the new sound-on-film system he dubbed Fox Movietone. One of the first feature films to be released in Fox Movietone was Sunrise (1927) directed by F. W. Murnau. Fox also used the system for the long-running newsreel series Fox Movietone News.
Movietone and other sound-on-film systems were in competition with sound-on-disc systems such as Warner Bros. Vitaphone. However, sound-on-film systems such as Movietone and RCA Photophone soon became the standard, and sound-on-disc fell into disuse.
