He was the brother of meteorologist and climatologist Rudolf Geiger.
Biography

In 1911 Geiger and John Mitchell Nuttall discovered the Geiger–Nuttall law (or rule) and performed experiments that led to Rutherford's atomic model.[6]
In 1912, Geiger was named head of radiation research at the German National Institute of Science and Technology in Berlin. There he worked with
In 1924, Geiger and Bothe carried the
In 1925, he began a teaching position at the
In 1929 Geiger was named professor of physics and director of research at the University of Tübingen where he made his first observations of a cosmic ray shower. In 1936 he took a position with the Technische Universität Berlin (Technical University of Berlin) where he continued to research cosmic rays, nuclear fission, and artificial radiation until his death in 1945.[2]
Beginning in 1939, after the discovery of
Although Geiger signed a petition against the Nazi government's interference with universities, he provided no support to colleague Hans Bethe (winner of the 1967 Nobel Prize in Physics) when he was fired for being Jewish.[11][12]
