Hans Georg Dehmelt

Hans Georg Dehmelt (born September 9, 1922 in Görlitz, Germany) is a German-born American physicist, who co-developed the ion trap technique with Wolfgang Paul, for which they both received the Nobel Prize in Physics in 1989. The technique was used for high precision measurement of the electron g-factor. At the age of ten Dehmelt enrolled in the 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 Ph.D. in 1950, both from... full article at wikipedia
