August Heissmeyer, German SS officer (died 1979)

August Friedrich Heissmeyer or Heißmeyer, was a German member of the Nazi Party who rose to become an SS-Obergruppenführer in the Schutzstaffel (SS). He held several major commands, including as the chief of the SS Main Office from 1935 to 1939 and as the Higher SS and Police Leader of the Berlin district from 1939 to 1945. He was also headed the National Political Institutes of Education, a network of elite secondary boarding schools established to train future leaders of the Nazi state. He was the husband of Gertrud Scholtz-Klink, the head of the National Socialist Women's League. After the Second World War, Heissmeyer underwent denazification, was convicted as a major offender and served three years in prison.

The Schutzstaffel was a major paramilitary organisation under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II.
