Rudolf Hoess was history's greatest mass murderer, the architect and SS Kommandant of the largest killing center ever created, Auschwitz, whose name has come to symbolize humanity's ultimate descent into evil. Responsible for exterminating 2,5 million people in World War II, he was a mild-mannered, happily married Catholic who enjoyed normal family life with his five children despite his view of the crematoria chimney stacks from his bedroom window.
