Rudolf Franz Ferdinand Höss (Höß, Hoess), SS-Obersturmbannführer and commandant of the Auschwitz death camp, is executed by hanging on the gallows he had constructed in Auschwitz next to the Auschwitz I crematorium.
During his interrogations and trial, he readily admits to his crimes, placing the number of people murdered at around 3 million. Höss even tells the judges that had he been ordered to put his own wife and five children into the ovens, he'd have done so.
When the British found and interviewed his wife, Hedwig Höss, they found her apartment filled with clothing and jewelry taken from the victims of Auschwitz. Hedwig Höss is also the one who turned her husband in.
Höss says that both Himmler and Eichmann visited Auschwitz, seeing the entire process. This makes it clear that the extermination of Jews was fully known by the hierarchy of the SS and the Nazi Party.
According to Gustave Gilbert, the American military psychologist sent to interview Höss:
"In all of the discussions, Höss is quite matter-of-fact and apathetic, shows some belated interest in the enormity of his crime, but gives the impression that it never would have occurred to him if somebody hadn't asked him. There is too much apathy to leave any suggestion of remorse and even the prospect of hanging does not unduly stress him.
One gets the general impression of a man who is intellectually normal, but with the schizoid apathy, insensitivity and lack of empathy that could hardly be more extreme in a frank psychotic."
Höss has the chance to ask Polish president Boleslaw Bierut for clemency, but refuses.
