Gesetz zur Verhütung erbkranken Nachwuchses
Theories on racial hygiene led to an elaborate sterilization program, with the goal of eliminating what the Nazis regarded as diseases harmful to the human race. Sterilized individuals, reasoned the Nazis, would not pass on their diseases to their children. The Sterilization Law, passed on July 14, 1933, also known as the Law for the Prevention of Hereditarily Diseased Offspring, called for the sterilization of any person who had a genetically determined illness. The Sterilization Law was drafted by some of Germany's top racial hygienists, including: Fritz Lenz, Alfred Ploetz, Ernst Rudin, Heinrich Himmler, Gerhard Wagner and Fritz Thyssen. Robert N. Proctor has shown that the list of illnesses which the law targeted included "feeblemindedness, schizophrenia, manic depression, epilepsy, Huntington's chorea, genetic blindness, and "severe alcoholism."" The estimated number of citizens who were sterilized in Nazi Germany ranges from 350,000 to 400,000. As a result of the Sterilization Law, sterilization medicine and research soon became one of the largest medical industries.
