Career
Sometime over the course of World World War II, all traces of Haffner were lost, including any professional and personal records that may have helped to indicate what led to his disappearance. There is just a single entry for him in the Berlin registry, where Haffner lived between 1925 and 1933. At the end of the 1930s, it is documented that he was summoned to appear at the Nazi Reichsschrifttumskammer (a writer’s union affiliated with the Third Reich), after which the details of his life remain unknown.
