Alan Hazeltine

Born 7 Aug 1886; died 24 May 1964 at age 77.(Louis) Alan Hazeltine was an American electrical engineer and physicist who invented the neutrodyne circuit, which made commercial radio possible. As one of the few experts in radio engineering at the outbreak of WW I, he designed a radio receiver for the U.S. Navy. In 1922, Hazeltine invented the "neutrodyne" receiver to eliminate the squeaks and howls of the early radio receivers, using neutralizing capacitors to in effect siphon off the high pitched squeals. The Hazeltine amplifier neutralized the grid-to-plate capacitative coupling which was a cause of oscillation in triode amplifiers. The neutrodyne was the first commercial receiver suited to general public reception. By 1927 some ten million of these receivers were being used by listeners in the U.S.
