Heinrich Heim (15 June 1900, Munich – 26 June 1988, Munich) was one of only two steonographers used by Hitler at the Berghof and the other Führerhauptquartiers.
He was primarily tasked with recording and typing up the notes of every single meeting and conversation Hitler had between 1941 and 1944.
After the war, the conversations were published as Hitler’s Table Talk.
This is Heim’s hiring letter/work permit (“Ausweis”) signed by Martin Bormann, which essentially brought him into the service of ‘der Fuhrer’ in August 1933.
