Thomas Townsend Brown (1905–1985) was an American physicist and inventor who claimed that high-voltage capacitors produced a force related to gravity, which became known as the Biefeld–Brown effect. He promoted the idea, called electrogravitics, to the military and aerospace industry for decades.
Assessment
Brown served in the Navy and worked on radar and other research. He was linked to NICAP's founding in 1956. Later experiments, including some in a vacuum, showed his "lifter" effect is caused by ion wind, the movement of charged air, not by any control of gravity. He remains a central figure in stories about secret anti-gravity research.
