William "Willy" Higinbotham (1910-1994) was an American physicist.
During the war, Willy Higinbotham worked at Los Alamos as leader of the Electronics Group in the Weapon Physics Division. The Trinity test - which he witnessed - as well as Hiroshima and Nagasaki had a profound effect on his psyche and he became strongly convinced of the need for an anti-nuclear proliferation movement.
Higinbotham co-founded the nuclear non-proliferation group, the Federation of American Scientists, and then took a job at Brookhaven laboratory in 1947, under the auspices of the Atomic Energy Commission. He worked there until his retirement in 1984. In 1958, he developed what is sometimes considered the first videogame, Tennis for Two. From 1974 onwards, Higinbotham held a position as the technical editor of the Journal of Nuclear Materials Management. He died in Gainesville, Georgia in 1994.
