Charlotte Houtermans (née Riefenstahl; 24 May 1899 in Bielefeld, Germany – 6 January 1993 in Northfield, Minnesota, United States) was a German physicist.
Riefenstahl began her studies at the Georg-August University of Göttingen in 1922, where her teachers included, among others, Max Born, Richard Courant, James Franck, David Hilbert, Emmy Noether, Robert Pohl, and Carl Runge.
She received her doctorate under Gustav Heinrich Johann Apollon Tammann[1] in 1927,[2] the same year as Robert Oppenheimer, under Born, and Fritz Houtermans, under Franck.
During a physics conference at the Black Sea resort of Batumi, Riefenstahl and Houtermans were married in August 1930, with Wolfgang Pauli and Rudolf Peierls as witnesses to the ceremony.
Charlotte managed to escape to Denmark and eventually went back to England and then on to the United States.
