He got out of Germany because at that time Germany became unsafe for Jewish people

One of the most interesting facts about Edward Teller is that he got out of Germany because at that time Germany became unsafe for Jewish people. Teller moved to the University of Göttingen in 1930, which was then one of the world's great physics centers due to the presence of Max Born and James Franck, but after Adolf Hitler became Chancellor of Germany in January 1933, Germany became unsafe for Jewish people, and he left with the help of the International Rescue Committee. He visited England briefly before moving to Copenhagen for a year to work with Niels Bohr. He married his long-term lover, Augusta Maria Mici Harkanyi, the sister of a friend, in February 1934. Edward and Mici got married at a Calvinist church because Mici was a Calvinist Christian. In September 1934, he returned to England.

Mici had been a student in Pittsburgh and wished to return to America. Teller's chance came in 1935 when she was invited to the United States by George Gamow to become a professor of physics at George Washington University, where he worked with Gamow until 1941. Teller proposed the Jahn-Teller effect at George Washington University in 1937, which distorts molecules in certain conditions and influences the chemical reactions of metals, particularly the color of certain metallic dyes. Teller and Hermann Arthur Jahn examined it as pure mathematical physics. Teller also made a significant contribution to surface physics and chemistry in cooperation with Stephen Brunauer and Paul Hugh Emmett: the Brunauer-Emmett-Teller (BET) isotherm. On March 6, 1941, Teller and Mici were naturalized citizens of the United States.
