Abstract

Francis Galton coined the word eugenics in the late nineteenth century in England to characterize the “noble heritage” and the “well-born.” Its statistical approach leads to biometry as the quantitative study of populations. As an organized movement, its main purpose was to apply the available knowledge on inheritance in order to shape the characters of the future generations. Since then, eugenistic studies mingled science with the social values of the ruling classes, distorting scientific practice. The early twentieth century gave rise to human genetics with strong eugenistic roots, assuming the role to prevent the “social degeneration” in modern industrial societies. This negative eugenistic movement developed into mandatory sterilization laws in several European countries and in the United States, and has its most dramatic achievement in the racial cleaning program of National Socialist Germany.
