Pioneer cinematographer Freeman Harrison Owens received the patent on the method of drawing and photographing stereoscopic pictures in relief (3-D technology). The patent was later bought by Entertaining Comics (EC) publisher Bill Gaines. Owens is credited with 11,812 inventions, among them the A.C. Nielsen Rating System, a plastic lens for Kodak, and the method of adding synchronized sound to film.
