15. Niemann’s Grandfather
At first, Derek Niemann tried to convince himself that his grandfather had been a lowly pen pusher, but subsequent research revealed a more sinister picture. Karl Niemann had been an SS officer, who had organized slave laborers in Nazi concentration camps such as Dachau and Auschwitz. He made the rounds of all the concentration camps to inspect their finances and oversaw an SS commercial enterprise that used a slave workforce, toiling in horrific conditions, to produce furniture and war supplies.
