|Title||Douglas Perham and Lee de Forest with 1893 Westinghouse light bulb|
At a reunion of electronics pioneers in Los Angeles in 1957, Dr. Lee de Forest (right) joins Douglas Perham to look at one of George Westinghouse's early light bulbs. The lamp was given to Perham, then aged six, by Westinghouse at 1893 Chicago's World Fair. Westinghouse urged young Doug to continue his interest both in electronics and in collecting apparatus documenting the evolution of electrical engineering. Perham had worked with de Forest, Herbert Van Etten and C.W. Logwood at Federal Telegraph, Palo Alto, in 1911-1912 as they developed the two devices that made large scale radio transmission possible, the Audion amplifier and the vacuum tube oscillator.
