Concentration camps. Crematoria. Gas chambers. Nazi medicine. Each brings to mind terrifying images of the universe created by Nazi Germany during its 12 short and violent years. All told, 11 million human beings were murdered by people who believed they were superior — physically, genetically, culturally — to other human beings. The Nazis and their allies built more than 10,000 camps across Europe to imprison their enemies and to implement their ruthless policy of radical racial eugenics that targeted 6 million Jews for extermination. That systematic murder was the Holocaust. But the Nazis also savagely murdered Gypsies, communists, Soviet POWs, Poles, the mentally ill, persons with genetic birth defects, the elderly, homosexuals, Jehovah’s Witnesses, intellectuals, outspoken clergy, and nearly anyone else who was labled an enemy of the Third Reich. Their deaths reached 5 million. During the summer of 2000 and the fall of 2001, I was able to document the world of terror created by the Nazis — in the camps they built, in the rooms where they plotted the extermination of millions of men, women, and children.
