Sir John Ambrose Fleming (sometimes also listed as Ambrose J. Fleming, 29 November 1849 - 18 April 1945) was a British electrical engineer and physicist. In November 1904 he invented and patented the two-electrode radio rectifier, which he called the oscillation valve. It was also called a thermionic valve, vacuum diode, kenotron, thermionic tube, or Fleming valve. This invention is often considered to have been the beginning of electronics.
