James C. “Jim” Keck (1924-2010) was an American physicist.
Keck was considered such an outstanding student of physics at Cornell that he was drafted into the Army Special Engineering Detachment (SED), after his sophomore year. With the SED, Keck was sent to Los Alamos, where he would remain until the end of the war. He met his future wife, fellow physicist Margaret Ramsey, while stationed at Los Alamos.
After the war he became a notable nuclear physicist in his own right, becoming Deputy Director of the Avco Everett Research Laboratory.
