Dr. Lee De Forest…Pioneer Of Electronic Media; Wireless To Talkies
Lee de Forest’s entire life was devoted to the invention of media technology primarily based on sound. He supplied the missing voice to radio and film.
Here is his 1957 appearance on ‘This Is Your Life’ from what I think is either Studio 1 or 3 from the brand new NBC Burbank. There are a few interesting shots from the control room and of the studio scattered around the first prat of the video. There is even a rare appearance from Allan B. Dumont.
Following a solid Yale education in Physics and Electricity, he spent the decade between 1900 and 1910 improving the wireless telegraph, but he quickly tired of its limitations of sending coded messages. In 1906 he filed his first patent for the vacuum tube he called the Audion, describing it as a detector of sound.
By 1907 he had invented an arc-based radiotelephone transmitter and Audion receiver, and he was writing about the possibility of sending music into homes by wireless. Between 1910 and 1920 he improved his Audion as a detector, an amplifier, and later a transmitter of radio. He started several radio stations. He was an early if not the first broadcaster of entertainment-based audio, primarily opera music.
Between 1920 to 1930 he invented, patented and improved upon a system of recording a sound track on a strip of film, thus allowing accurate synchronization with the picture. Lee de Forest had invented the Talking Motion Picture. Enjoy and share! -Bobby Ellerbee

Many patents and patent controversies. Long battle with Major Armstrong over the regenerative circuits. Worth reading Empire of the Air – The Men Who Made Radio.
But from what I remember he was clouded in controversy.
