Daniel Kleppner ( born December 16, 1932 in New York City ) is an American physicist. He is Lester Wolfe Professor Emeritus of Physics at MIT and co-director of the MIT - Harvard Center for Ultracold Atoms.
Kleppner studied at Williams College (Bachelor 1953), at Cambridge University (Bachelor 1955) and his PhD in 1959 at Harvard University. After that, he stayed at Harvard, where he rose to become Assistant Professor, before he was associate professor at MIT in 1966. From 1974 he was a professor there from 1985 and Lester Wolfe Professor. From 2007 he is a professor emeritus.
Along with Norman Ramsey 1960, he developed the hydrogen maser, which as atomic clock with previously unattainable precision was used later. An applications of this early work is the GPS system. In the 1970 made Kleppner pioneering work in the physics of Rydberg atoms.
Awards and prizes
Since 1986 he is a member of the National Academy of Sciences. 1988 to 1990 he was secretary of the International Union of Pure and Applied Physics.
Together with Robert Kolenkow he wrote a popular introduction to the mechanics for advanced students.
