Rudolf Höss
Höss's father was a former German army officer who had served in German East Africa (a German colony that included what are now Burundi, Rwanda, and part of Tanzania).  After leaving the army, he ran a tea and coffee business.  He brought up his son based on strict Catholic beliefs, and with military discipline.  He had decided that Höss would become a Catholic priest.  During Höss's early childhood, he was constantly being told about sin, guilt, and the need to do penance.
