Rudolf Franz Ferdinand Höss (also Höß, Hoeß or Hoess; 25 November 1901 – 16 April 1947) was SS-Obersturmbannführer and the longest serving commandant of Auschwitz concentration camp in World War II. He tested and carried into effect various methods to accelerate Hitler's plan to systematically exterminate the Jewish population of Nazi-occupied Europe, known as the Final Solution. Höss introduced pesticide Zyklon B containing hydrogen cyanide to the killing process, thereby allowing soldiers at Auschwitz to murder 2,000 people every hour. He created the largest installation for the continuous annihilation of human beings ever known.
Höss joined the Nazi Party in 1922 and the SS in 1934. From 4 May 1940 to November 1943, and again from 8 May 1944 to 18 January 1945 he was in charge of Auschwitz where more than a million people were killed before the defeat of Germany. He was hanged in 1947 following a trial in Warsaw.(Wikipedia)
