Phonofilm is an optical sound-on-film system developed by
inventors Lee de Forest and Theodore Case in the 1920s. On 15 April
1923, DeForest premiered 18 short films made in Phonofilm including
vaudeville acts, musical performers, opera, and ballet at the Rivoli
Theater at 1620 Broadway in New York City. The Rivoli's music
director Hugo Riesenfeld co-hosted the presentation. The printed
program gave credit to the "DeForest-Case Patents", but according
to a letter Theodore Case wrote to DeForest immediately after the
event, no credit was given to Case during the presentation itself.
Case also expressed his displeasure that the program credited only
the "DeForest-Case Patents", as Phonofilm's success was fully due to
the work of Case and his Case Research Lab.
