Hans Bernd Gisevius

Hans Bernd Gisevius (July 14, 1904 – February 23, 1974) was a German diplomat and intelligence officer during World War II. A covert opponent of the Nazi regime, he served as a liaison in Zürich between Allen Dulles, station chief for the American OSS and the German Resistance forces in Germany.

Gisevius was born in Arnsberg in the Prussian Province of Westphalia. After law school, he joined the Prussian Interior Ministry in 1933 and was assigned to the newly formed Geheime Staatspolizei, or Gestapo. After joining the Gestapo, he immediately had disagreements with his senior, Rudolf Diels, and was discharged. He continued with police work in the Interior Ministry. When Himmler took over Police functions in 1936 in the German Reich, he removed Gisevius from office.

Throughout his time working for the Gestapo Gisevius described himself as living in constant fear, entering and exiting through the back door, clutching a pistol at his side - all resultant from his misgivings with the terror apparatus to which he was assigned, since according to him, it was like "living in a den of murderers". Gisevius later transferred to the Reich Ministry of the Interior. Although he had no position of power, he maintained connections, notably to Arthur Nebe, that kept him informed of the political background. Gisevius joined the secret opposition to Hitler, began gathering evidence of Nazi crimes (for use in a later prosecution) and attempted to restrain the increasing power of Heinrich Himmler and the SS. He maintained links with Hans Oster and Hjalmar Schacht
