Samuel Allison

Samuel King Allison (November 13, 1900 – September 15, 1965) was an American physicist, most notable for his role in the Manhattan Project, for which he was awarded the Medal for Merit. He was director of the Metallurgical Laboratory from 1943 until 1944, and later worked at the Los Alamos Laboratory — where he rode herd on the final stages of the project as part of the Cowpuncher Committee, and read the countdown for the detonation of the Trinity nuclear test. After the war he was involved in the scientists movement, lobbying for civilian control of nuclear weapons.
