The first public demonstration of sound recorded simultaneously with pictures on film took place at the Urbana campus on June 9, 1922. Joseph T. Tykociner's double-feature motion picture included ringing a bell and reading the Gettysburg Address. The invention was not patented. The first commercial talking film in 1927 used a phonograph, and Tykociner's invention was only later recognized. It is still used for sound on film.
Nope - about 46 other people did, too - you're just more tech-savvy than most!
