詹姆斯·查德威克
In 1912, Geiger was named head of radiation research at the German National Institute of Science and Technology in Berlin. There he worked with Walter Bothe (winner of the 1954 Nobel Prize in Physics) and James Chadwick (winner of the 1935 Nobel Prize in Physics). Work was interrupted when Geiger served in the German military during World War I as an artillery officer from 1914 to 1918.
