EUGENICS. The term eugenics, derived from the Greek eugenes, was first coined by the English mathematician and geographer Francis Galton (1822–1911) in his Inquiries into Human Faculty and Its Development (1883) to refer to one born "good in stock, hereditarily endowed with noble qualities." As an intellectual and social movement in the early twentieth century, eugenics came to mean, in the words of one of its strongest American supporters, Charles B. Davenport (1866–1944), "the improvement of the human race by better breeding." For both Galton and Davenport, better breeding involved using the known scientific principles of heredity. Eugenics was the human counterpart of scientific animal and plant husbandry. It seemed ironic to eugenicists that human beings paid such careful attention to the pedigrees of their farm and domestic stock while ignoring the pedigrees of their children. The ideology of eugenics was characterized by a strong belief in the power of heredity in determining physical, physiological, and mental traits; an inherent ethnocentrism and racism that included belief in the inferiority of some races and superiority of others (a view extended to ethnic groups and social classes as well); and a belief in the power of science, rationally employed, to solve social problems, including ones so seemingly intractable as pauperism, crime, violence, urban decay, prostitution, alcoholism, and various forms of mental disease, including manic depression and "feeblemindedness" (retardation).
Eugenics movements did not begin to arise in Europe or the United States until the first decade of the twentieth century, and they did not become generally effective in promoting social and political programs nationally or internationally until after 1910. The earliest eugenics movements were founded in Germany in 1904, in Britain in 1907, and in the United States in 1908–1910. Other eugenics movements appeared subsequently around the world: in Western Europe (France, Norway, Sweden, Denmark), Russia, Latin America (Cuba, Brazil, Mexico), Canada, and Asia (Japan). However, it was in the United States, Britain, and Germany that eugenics as an intellectual and social movement made its greatest strides and, from eugenicists' point of view, achieved its greatest ideological and political effects.
