Electronics
The Edison effect discovered in 1882, consists of an electric current flowing between a heated cathode and an anode in an evacuated tube. It was not understood how electric current could pass through a vacuum until J.J. Thomson identified cathode rays as streams of electrons. This discovery brought about the invention of the thermionic diode by John Ambrose Fleming, a device that could detect radiotelegraphic signals. The diode was widely overlooked until the invention of the triode by Lee De Forest, which revolutionized radio communication.
