This detailed study of the causes of the 20th century Holocaust documents the influence of many entities, not only Darwinism and Eugenics, but, importantly, what Dwight Eisenhower called the Military Industrial Complex. The efficiency and extent of the Holocaust was only possible due to the critical support of both German and American industry. The blame for this most evil act in history lies not only with the leading Nazis, but also with academia and major corporations, including Henry Ford and the Ford Motor Company and IBM's German subsidiary. Insuring that a similar Holocaust never reoccurs requires that one understand the many factors that caused the WWII Holocaust.
