    Lee De Forest (August 26, 1873 – June 30, 1961) was an American inventor with over 300 patents to his credit.

    De Forest invented the triode vacuum tube, which ushered in a new age of electronics through its use in the amplification of electrical signals. He made some of the earliest motion pictures with sound, and the system he devised was later adopted by the large Hollywood studios.

    De Forest's zeal for promoting the mass media helped shape it into the force it is today.
