At first glance, Martin Heinrich Corten's biography appears to be the classic story of a German physician persecuted by the Nazis. Because of his “Jewish descent,” Corten lost his position as a pathologist in Berlin and later his license to practice medicine. Emigration failed. But Corten was not a typical Nazi victim. In 1933, he applied for membership in the Nazi Party, and during the last two years of the war he collaborated with the Gestapo as the Hamburg representative of the “Reich Association of Jews in Germany.” Although he tried to provide basic welfare and health care for Hamburg's remaining Jewish population, he was heavily involved in the deportation of Jewish citizens to concentration and extermination camps. After the war, Corten thus came into conflict with the Jewish community and lost his position as medical director of the Jewish Hospital in Hamburg. He became a “double outcast” and was unable to re-establish himself in academia. His biography, however, is a vivid example of how the line between victim and perpetrator can be blurred.
