Hoover, Edison featured speakers at dinner honoring Lee de Forest

摘要

On April 8, 1952, Dr. Lee de Forest was honored by a dinner at the Waldorf-Astoria Hotel celebrating the 50th anniversary of his entry into commercial wireless telegraphy, as the art was then known. The event also commemorated the 45th anniversary of the birth of the 3-element tube, or “audion.” One of the most far-reaching inventions of this century, this tube is used in every broadcast and television transmitter and receiver, in telecommunications by wire and radio, in electronic devices of every kind, including radar and guided missiles, and in every motion picture theatre. Dr. de Forest, the “Father of Radio,” is now 79.
