In March 1938, Hitler arrived in Vienna. Soon after, Freud's house and office were ransacked, his passport was confiscated and Anna was taken in for interrogation by the Gestapo. After a significant amount of international pressure, the Freuds were allowed to leave Austria for London in June of 1938. Four of Freud's sisters were not so lucky; unable to secure exit visas, one sister died in the Theresienstadt ghetto and the remaining three were put to death at the Treblinka extermination camp in Poland.
Rumors about the fate of the Freuds spread quickly during the initial days of the Nazi's Austrian occupation, to such an extent that Wilhelm Stekel, one of his former pupils, wrote to a Dr. L. J. London in New Hampshire to ask if he had heard the news about Freud's imprisonment. The real purpose of the letter, however, was to beg London to send him an invitation to come to New Hampshire under the pretenses of participating a medical conference. As Stekel says in his letter, "Please act as quickly as possible because frontiers could be closed at any time."
To see this letter, and correspondence from other noteworthy psychoanalysts like Carl Jung or Fritz Wittels, come to Special Collections and ask to see the L. J. London Papers (MS-1062).
