Hans Georg Dehmelt
(9 September 1922 – 7 March 2017) was a German and American physicist, who was awarded a
Nobel Prize in Physics
in 1989, for co-developing the
ion trap
technique (
Penning trap
) with
Wolfgang Paul
, for which they shared one-half of the prize (the other half of the Prize in that year was awarded to
Norman Foster Ramsey
). Their technique was used for high precision measurement of the
electron
magnetic moment
. At the age of ten Dehmelt enrolled in the
Berlinisches Gymnasium zum Grauen Kloster
, a
Latin
school in
Berlin
, where he was admitted on a scholarship. After graduating in 1940, he volunteered for service in the
German Army
, which ordered him to attend the
University of Breslau
to study physics in 1943. After a year of study he returned to army service and was captured during the
Battle of the Bulge
. After his release from an American prisoner of war camp in 1946, Dehmelt returned to his study of physics at the
University of Göttingen
, where he supported himself by repairing and bartering old, pre-war radio sets. He completed his master's thesis in 1948 and received his PhD in 1950, both from the University of Göttingen. He was then invited to
Duke University
as a postdoctoral associate, emigrating in 1952. 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.
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. In the 1960s, Dehmelt and his students worked on spectroscopy of hydrogen and helium ions. The electron was finally isolated in 1973 with David Wineland, who continued work on trapped ions at NIST. He created the first
geonium atom
in 1976, which he then used to measure precise magnetic moments of the electron and positron with R. S. Van Dyck into the 1980s, work that led to his Nobel prize. In 1979 Dehmelt led a team that took the first photo of a single atom. He continued work on
ion traps
at the
University of Washington
, until his retirement in October 2002. In May 2010, he was honoured as one of Washington's Nobel laureates by
Crown Princess Victoria of Sweden
at a special event in Seattle.
He was married to Irmgard Lassow, now deceased, and the couple had a son, Gerd, also deceased. In 1989 Dehmelt married Diana Dundore, a physician. Dehmelt died on March 7, 2017 in Seattle, Washington, aged 94.
