Federal Telegraph Company
The Federal Telegraph Company was a United States communications company that played a pivotal role in the 20th century in the development of radio communications. Founded in Palo Alto, California in 1909 by Cyril Frank Elwell, the company would eventually merge in August 1927 with the Mackay Companies. In 1911-13, Lee De Forest and two assistants worked at FTC on the first vacuum tube amplifier and oscillator, which De Forest called the "Oscillaton" after his earlier Audion.
The company remained a separate entity within the Mackay Companies, however, and when International Telephone and Telegraph (ITT) purchased the Mackay Companies in 1928 Federal remained a component of the Mackay structure as a manufacturing entity.
In 1940, Sosthenes Behn moved Federal Telegraph under ITT directly so that its manufacturing capabilities could help ITT replace those in Europe that had been shut down because of the war and the Fall of France.
In 1954, FTR changed its name from Federal Telegraph and Radio Corporation - an IT&T associate to Federal Telegraph and Radio Company - division of IT&T, and its research division became the Federal Telecommunications Laboratories, both continuing as subsidiaries of ITT after World War II through at least the 1950s.
