De Forest, Lee,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.

De Forest, Lee
Born Aug. 26, 1873, in Council Bluffs, Iowa; died June 30, 1961, in Hollywood. American radio engineer.
De Forest graduated from Yale University in 1896. During his career, he headed a number of radio engineering enterprises in the United States. De Forest invented the triode in 1906 (patented 1907) and used it to design a vacuum-tube detector and amplifier known as the Audion tube. He developed a system of radiotelegraphy that was adopted by the army and navy of the United States in the early 20th century. De Forest also worked in radiotelephony, and in 1910 he transmitted a musical performance in the first broadcast of its kind. In 1916 he developed a sound-on-film optical-recording system called phonofilm. De Forest was responsible for many other inventions in radio engineering and talking motion pictures.
