Norman F. Ramsey, the Nobel Prize-winning physicist who developed a precise method to probe the structure of atoms and molecules and used it to devise a remarkably exact way to keep time, died on Friday in Wayland, Mass. He was 96.
Norman Foster Ramsey Jr. was born on Aug. 27, 1915, in Washington, the son of Minna Bauer Ramsey, a mathematics teacher, and Norman Foster Ramsey, an Army officer. After receiving his Ph.D. under Dr. Rabi at Columbia, he worked at the M.I.T. Radiation Laboratory and served as a radar consultant to the secretary of war. In 1943 he went to Los Alamos, N.M., to work on the Manhattan Project, leading a team that helped assemble the bombs dropped on Hiroshima and Nagasaki, Japan.
