Arthur Nebe, German SS officer (d. 1945)
Arthur Nebe (German: [ˈaʁtuːɐ̯ ˈneːbə] (listen); 13 November 1894 – 21 March 1945) was a key functionary in the security and police apparatus of Nazi Germany and from 1941, a major perpetrator of the Holocaust.

Nebe rose through the ranks of the Prussian police force to become head of Nazi Germany's Criminal Police (Kriminalpolizei; Kripo) in 1936, which was amalgamated into the Reich Security Main Office (RSHA) in 1939. Before the 1941 German invasion of the Soviet Union, Nebe volunteered to serve as the commanding officer of Einsatzgruppe B, one of the four mobile death squads of the SS. The unit was deployed in the Army Group Centre Rear Area, in modern-day Belarus, and reported over 45,000 victims by November 1941. In late 1941, Nebe was posted back to Berlin and resumed his career with the RSHA. Nebe commanded the Kripo until he was denounced and executed after the failed attempt to kill Adolf Hitler in July 1944.

After the war, Nebe's career and involvement with the 20 July plot against Hitler were the subject of several apologetic accounts by surviving members of the plot, who portrayed him as a professional policeman and a dedicated anti-Nazi. These portrayals have since been discredited by historians who describe him as an opportunist and a mass murderer driven by racism and careerism.
