Rolf Isaaksohn
Rolf Isaaksohn was a Jewish collaborator working for the Nazis. His mistress was then another collaborator Stella Goldschlag. The pair, trained by the Gestapo, became members of the Jüdischer Fahndungsdienst (Jewish tracking unit), made up of about 20 young men and women known as Greifer (the catcher). For each hiding Jew who was arrested with their help, they were awarded a prize of 200 marks. With weapons and papers identifying them as Gestapo agents, they were able to move freely around the city without having to wear the Star of David.
Stella and Rolf were perhaps the most successful in catching Jews, or at least they were the most famous collaborators of the Gestapo. They often acted together, but also hunted Jews in hiding themselves.
Rolf, who was described by witnesses as an unscrupulous and aggressive man, usually wore a long leather coat and a Trilby hat. He looked like a real Gestapo officer. Together with Stalla, he often acted in entertainment venues still visited by Jews who were temporarily fleeing the boredom or stress of living in hiding. Stella and Rolf knew many of them by name or by face. Rolf frequently threatened his victims with weapons and used violence before handing them over to the Gestapo.
There were frequent quarrels and serious arguments between Rolf and Stella, which sometimes ended in beating up Stella. Because their commander feared they would drift apart and he would lose control of such a successful couple, he forced them into a marriage they entered into in 1944. It turned out, however, that the period in which the loving couple successfully hunted the hiding Jews was definitely over. They both had extramarital lovers.
The post-war fate of Rolf Isaaksohn is unknown. Despite an arrest warrant issued by the Berlin police shortly after the war, he was never tracked down and never suffered any consequences for his actions.
