Margit von Mises on her husband's concern about a great crash coming in the late 1920s

One day Lu told me he had been offered a high position at the Credit Anstalt, the foremost banking institution in Vienna, but that he had decided not to accept it. When I asked him the reason for his refusal, he told me that a great ‘crash’ would be coming and that he did not want his name in any way connected with it. He preferred to write and teach.
