Karl Silberbauer - Biography

Biography

Born in Vienna, Silberbauer served in the Austrian military before following his father into the police force in 1935. Four years later, he joined the Gestapo, moved to the Netherlands, and in 1943 transferred to the SD in The Hague.

On August 4, 1944, he was instructed by his superior, Julius Dettmann, to investigate a tip-off that Jews were being hidden in upstairs rooms at Prinsengracht 263. He took a few officers with him and interrogated Victor Kugler about the entrance to the hiding place. Miep Gies was also questioned, but allowed to stay on the premises after Kugler and his associate Johannes Kleiman, together with Otto Frank, Edith Frank-Holländer, Margot Frank, Anne Frank, Hermann van Pels, Auguste van Pels, Peter van Pels, and Fritz Pfeffer, were arrested and taken to Gestapo headquarters. From there the eight who had been in hiding were sent to the Westerbork transit camp, and then to the Bergen-Belsen concentration camp. Victor Kugler and Jo Kleiman were sent to work camps. Of the ten, only Otto Frank, Kugler, and Kleiman survived.

Silberbauer returned to Vienna in April 1945 to begin serving fourteen months imprisonment on a charge of unnecessary brutality while interrogating members of the Communist Party of Germany. After the war, Silberbauer was used by the West German intelligence service, or Bundesnachrichtendienst, to infiltrate neo-Nazi and Pro-Soviet organizations.

He was reinstated by the Viennese Kriminalpolizei (Kripo) in 1954, four years after the German publication of Anne Frank's diary.

Holocaust survivor and Nazi hunter Simon Wiesenthal began searching for Silberbauer in 1958, when Wiesenthal was challenged by Holocaust deniers to prove the existence of Anne Frank. Silberbauer's name had been disclosed in 1948 during the Dutch police investigation into the denunciation and arrest of those hiding in the Secret Annex. The Dutch police detectives who had assisted with the raid were identified by Miep Gies and claimed to remember nothing, other than the name of their superior, Karl Silberbauer.

Wiesenthal requested the help of Anne's father, Otto Frank, who refused. Otto Frank felt that those responsible for the original denunciation, not the arresting officer, bore the greatest responsibility. Wiesenthal disagreed and began a search for Silberbauer. In October 1963, after investigating and ruling out fourteen other Austrians with the same name, the Wiesenthal Center tracked Silberbauer down.

Silberbauer was suspended from the Vienna police force pending an investigation into his wartime activities. When the Dutch media learned of his whereabouts, they descended on his home. Silberbauer freely admitted to them that he had arrested Anne Frank. The story was broken to the world's press on November 11, 1963. Meanwhile, the Dutch police's investigation into the identity of the informer was reopened.
