An About VG copy. de Forest "was an American inventor, self-described 'Father of Radio', and a pioneer in the development of sound-on-film recording used for motion pictures.. His most famous invention, in 1906, was the three-element 'Audion' (triode) vacuum tube, the first practical amplification device. Although De Forest had only a limited understanding of how it worked, it was the foundation of the field of electronics, making possible radio broadcasting, long distance telephone lines, and talking motion pictures, among countless other applications."
