Ernst Kaltenbrunner
Following "Anschluss" in 1938, the Viennese-based organization fell under the control of Nazi Germany, and the Commission's headquarters were eventually moved to Berlin in 1942. Most member states withdrew their support during this period. From 1938 to 1945, the presidents of the ICPC included Otto Steinhäusl, Reinhard Heydrich, Arthur Nebe, and Ernst Kaltenbrunner. All were generals in the SS, and Kaltenbrunner was the highest ranking SS officer executed after the Nuremberg Trials.
