Rudolf Diels (16 December 1900 - 18 November 1957) was a German politician and head of the Gestapo in 1933-34. He is also referred to as an SS-Oberführer. He was a protégé of Hermann Göring.
Diels was born in Berghausen in the Taunus, the son of a farmer. He served in the army during World War I and afterwards studied law at the University of Marburg from 1919. At university he had a reputation as a drinker and philanderer.:64 While there he also received a number of dueling scars resulting from the academic fencing once practised by young upper-class Austrians and Germans in trying to prove their manhood. The scars did not greatly detract from his good looks and in fact imparted a quite striking appearance.:116
He joined the Prussian interior ministry in 1930 and was promoted to an advisory position in the Prussian police in 1932, targeting political radicals, both Communists and Nazis. He was head of the Prussian Political Police when Adolf Hitler came to power. Göring was made minister for Prussia in 1933, replacing Carl Severing, and was impressed with Diels' work and new-found commitment to the Nazi Party. In April 1933 Göring appointed him as chief of the new Prussian state police department 1A, concerned with political crimes. Department 1A was soon renamed the Geheime Staatspolizei (Secret State Police), or Gestapo. On February 27, 1933 the Reichstag fire occurred, and Diels was the main interrogator of the principal accused, Marinus van der Lubbe. He also ordered Arthur Nebe to arrange the killing of Gregor Strasser in October 1933; ironically Strasser was later killed during the Night of the Long Knives in which Diels himself was almost killed.
Diels soon attracted the attention of political rivals, including Heinrich Himmler and Reinhard Heydrich. Himmler was head of the SS at the time.:138 Effectively smeared, but with Göring's aid, he narrowly avoided execution during the Night of the Long Knives, fleeing his post for five weeks. Diels was dismissed on 1 April 1934 and control of the Gestapo was formally given to Himmler on 20 April 1934. Heydrich, named chief of the Gestapo by Himmler on 22 April 1934, also continued as head of the SS Security Service (Sicherheitsdienst, SD). Thereafter, Diels was briefly Deputy Police President of Berlin before being appointed to the local government of Cologne as a Regierungspräsident.
He maintained his association with Göring, marrying a cousin of his protector. Göring saved him from prison on a number of occasions, notably once in 1940 when he declined to order the arrest of Jews, and more vitally in 1944 after the 20 July Plot to assassinate Hitler.
After 1950 he served in the post-war government of Lower Saxony,  and then in the Ministry of the Interior, until his retirement in 1953. He died on 18 November 1957 when his rifle accidentally discharged while he was hunting.:362
Diels' memoirs, Lucifer Ante Portas: Von Severing bis Heydrich, were published in 1950. A less cautious work was published after his retirement, Der Fall Otto John ("The Case of Otto John") (1954).
