Ramsey, Norman Foster, Jr.,

1915–2011, American physicist, b. Washington, D.C., Ph.D. Columbia, 1940. A member of the faculty at Harvard from 1947 and the Higgins professor of physics from 1966 (emeritus from 1987), Ramsey also held several posts with such government and international agencies as NATO and the U.S. Atomic Energy Commission. He was awarded the 1989 Nobel Prize in Physics for the invention of the separated oscillatory field method, or Ramsey method, which had important applications in the construction of atomic clocksatomic clock,
electric or electronic timekeeping device that is controlled by atomic or molecular oscillations. A timekeeping device must contain or be connected to some apparatus that oscillates at a uniform rate to control the rate of movement of its hands or the rate of
