About Hans Georg Dehmelt
Hans Georg Dehmelt was a German and American physicist, who was awarded a Nobel Prize in Physics in 1989, for co-developing the ion trap technique with Wolfgang Paul, for which they shared one-half of the prize. Their technique was used for high precision measurement of the electron magnetic moment. In 1979 Dehmelt led a team that took the first photo of a single atom. In 1955 he built his first electron impact tube in George Volkoff's laboratory at the University of British Columbia and experimented on paramagnetic resonances in polarized atoms and free electrons. He created the first geonium atom in 1976, which he then used to measure precise magnetic moments of the electron and positron with R. Dehmelt became an assistant professor at the University of Washington in Seattle, Washington in 1955, an associate professor in 1958, and a full professor in 1961.
