The organization now known as INTERPOL (International Criminal Police Organization) was founded in 1923 and headquartered in Vienna. When Austria was annexed by Nazi Germany in 1938, the organization came under the control of the Nazis. From 1940 to 1942, the President of INTERPOL was none other than the murderer and sociopath, Reinhard Heydrich, the infamous “Blonde Beast” of Nazi Germany. Among his many offices, Heydrich was the head of the Gestapo. After being sent to govern Nazi occupied Czechoslovakia, Heydrich was assassinated by Czech partisans.
