After the Nazis came to power, after Kristallnacht his family's business was seized by the Nazis and Halberstadt was interred in Bergen-Belsen concentration camp by the Nazis because he was Jewish.^[2][4][6] He then fled Germany at the age of 56 with what he could carry, first to London, and then San Francisco in 1940.^[2][4]
