Born in Rüstingen, Oldenburg, the son of a provincial innkeeper, he was educated to doctorate level in law at Marburg University but struggled to find employment in an economically depressed Weimar Germany.[2] He joined the Nazi Party in January 1932 and the SS the following month.[3] With no military experience he initially floundered but soon attracted the attentions of Reinhard Heydrich, who valued academic expertise, and he was transferred to the Sicherheitsdienst (SD).[4]
