Joseph Tykociński-Tykociner

He received a jeweled gold watch from Czar Nicholas II for setting up a radio communication system for the Russian fleet.

When Tykociner demonstrated the first sound-on-film motion picture recordings the projector had a photoelectric cell made by his Illinois colleague Jakob Kunz at its heart.

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.

[1] A dispute between Tykociner and university president David Kinley over patent rights to the process thwarted its commercial application.

DeForest, working with Theodore Case, produced several short films in 1921 and 1922, and introduced Phonofilm at a presentation at the Rivoli Theater in New York City on April 15, 1923.

[1] After his official retirement in 1946, he did research in a new field he termed "zetetics," (not to be confused with zeteticism, Marcello Truzzi's term for scientific skepticism), which Tykociński-Tykociner described as the collection and systematization of "all information about research activities, including creative processes, with the view of extending that knowledge which leads to discoveries, inventions, and the solution of human problems."
