Lee De Forest 1873-1961, American inventor, b. Council Bluffs, Iowa, grad. Yale, 1896. He was a pioneer in the development of wireless telegraphy, sound pictures, and television. His triode (1906) made practicable transcontinental telephony, both wire and wireless, and led to the foundation of the radio industry. He is frequently called "the father of radio." The first high-powered naval radio stations were designed and installed by him.

Bibliography: See his autobiography (1950); biography by I. E. Levine (1964).
