Eugenics is a nice-sounding word, combining as it does the Greek words for "good" and "birth." And Francis Galton, who made up the word and the idea, proposed Eugenics "for the betterment of mankind." But that's as far as the nice-sounding stuff goes. The actual definition is rather horrible: the controlled and selective breeding of the human race. Galton based his ideas on the theories of his cousin: Charles Darwin. By the beginning of the 20th century, when Darwin's theory was safely embraced by the scientific establishment, Eugenics was getting good press.
