Josef Kramer (10 November 1906 – 13 December 1945) was the Commandant of Auschwitz-Birkenau (from 8 May 1944 to 25 November 1944) and of the Bergen-Belsen concentration camp (from December 1944 to its liberation, April 15, 1945).
Dubbed The Beast of Belsen by camp inmates, he was a notorious German Nazi war criminal, directly responsible for the deaths of thousands of people.
He was detained by the British Army after the Second World War, convicted of war crimes and hanged on the gallows in Hamelin prison by British executioner Albert Pierrepoint.
