Josef Mengele
When cereals were scarce, sawdust was sometimes an ingredient in Kommissbrot. Auschwitz concentration camp survivor, Dr. Miklós Nyiszli, reports in "Auschwitz: A Doctor's Eyewitness Account" that the subaltern medical staff, who served Dr. Josef Mengele, subsisted on "bread made from wild chestnuts sprinkled with sawdust."
