Karl_Silberbauer

Karl Josef Silberbauer (21 June 1911 – 2 September 1972) was an Austrian police officer, Schutzstaffel (SS) member, and undercover investigator for the West German Bundesnachrichtendienst (federal intelligence service). He was stationed in Nazi-occupied Amsterdam during World War II, where he was promoted to the rank of Hauptscharführer (master sergeant). In 1963, Silberbauer, by then an inspector in the Vienna police, was exposed as the commander of the 1944 Gestapo raid on the Anne Frank House Secret Annex and the arrests of Anne Frank, her fellow fugitives, and two of their protectors, Victor Kugler and Johannes Kleiman.
