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 clocks and also contributed to the development of nuclear magnetic resonance. He shared the prize with Hans G. Dehmelt and Wolfgang Paul. Ramsey also developed hydrogen maser atomic clock in 1960 with David Kleppner.
