Heydrich remained the RSHA chief until his assassination in 1942. In January 1943 Himmler delegated the office to SS-"Obergruppenführer" and General of Police Ernst Kaltenbrunner, who headed the RSHA until the end of World War II in Europe. The head of the RSHA was also known as the CSSD or Chef der Sicherheitspolizei und des SD (Chief of the Security Police and of the Security Service).
