Julius Dettmann (January 23, 1894 – July 25, 1945) was a German Schutzstaffel (SS) officer in the Sicherheitsdienst (Security Service; SD), known as the officer who had Anne Frank and her relatives and friends arrested and deported while they were hiding in the secret annex.
He was stationed in Amsterdam during the German occupation of the Netherlands and was promoted to SS-Obersturmführer (lieutenant) on November 9, 1942.
[citation needed] On August 4, 1944, he received a phone call reporting that there were Jews hidden in the premises of 263 Prinsengracht in Amsterdam.
Silberbauer and his contingent of NSB plain-clothes officers raided the building and arrested the eight people in hiding who, after questioning at SD headquarters, were deported to the Westerbork transit camp and from there, to various labour and concentration camps.
On August 17, 1956, his remains were transferred to Ysselsteyn German war cemetery.
