Fritz Reiche
Fritz Reiche was a student of Max Planck and a colleague of Albert Einstein, who was active in, and made important contributions to the early development of quantum mechanics including co-authoring the Thomas-Reiche-Kuhn sum rule.
From 1913 to 1920 as privatdozent he worked and taught under Planck in Berlin. Reiche published more than 55 scientific papers and books including The Quantum Theory.
He became a professor in 1921 at the University of Breslau and then was dismissed as a Jew from his academic position in 1933. Eventually, with the help of Ladenburg, Einstein, and the Emergency Committee in Aid of Displaced Foreign Scholars, Reiche emigrated with his family to the United States in 1941 and went on to work with NASA and the United States Navy on projects related to supersonic flow.
