Today in 1922, Joseph Tykociński-Tykociner, University of Illinois's first research professor of engineering, publicly demonstrated for the first time a motion picture with a soundtrack optically recorded directly onto the film.
In the first sounds ever publicly heard from a composite image-and-audio film, Helena Tykociner, the inventor's wife, spoke the words, "I will ring," and then rang a bell. Next, Ellery Paine, head of the university's Department of Electrical Engineering, recited the Gettysburg Address.
