In a chapter titled “Eugenics in Hitler’s Germany,” Robert N. Proctor opens by writing, “we like to think that medicine is a force for healing in the world, but we should also not forget that, in the wrong political climate, medicine can join with evil to produce monstrosities. Such was the case in the Nazi era.” Proctor then goes on to list the sterilization of disabled people as one of the “most horrific crimes of the Nazis,” along with “cruel medical experiments, pernicious racial theories, and industrial-scale murder.” While Jews are the most notable victims of the Holocaust, there were many others viewed by the Nazis as undesirable, including homosexuals, the physically and mentally disabled, Roma, Poles and other Slavic people, Jehovah’s Witnesses, and members of opposing political groups. The sterilization and/or killing of those with disabilities were “crimes committed in the guise of medicine.” However well-intentioned these practices may have started out, they clearly became tragic excuses to control the population and help promote the Aryan race.
