Pioneer Electronics Research Laboratory
California State Historic Landmark 836
#836 Electronics Research Laboratory
Original site of the laboratory and factory of Federal Telegraph Company, founded in 1909 by Cyril F. Elwell. Here, with two assistants, Dr. Lee deForest, inventor of the three-element radio vacuum tube, devised in 1911-13 the first vacuum tube amplifier and oscillator. World-wide developments based on this research led to modern radio communication, television, and the electronics age.
Nothing remains of this site.
