Ernst Kaltenbrunner
Following Germany's defeat in World War II, the tribunal at the Nuremberg trials officially declared the SD a criminal organisation, along with the rest of Heydrich's RSHA (including the Gestapo) both individually and as branches of the SS in the collective. Heydrich's successor, Ernst Kaltenbrunner, was convicted of war crimes and crimes against humanity at the Nuremberg trials, sentenced to death and hanged in 1946.
