Over the past two decades, the scholarship on eugenics has grown rapidly as historians of science have shown increasing interest in investigating the complex, historical interactions between science and social theory. As a movement that began as a statis-tical proof of a hereditary theory and developed into a blueprint for societal improvement, eugenical science exemplifies the delicacy of the science-society boundary. Thus far, scholarly works on eugenics have approached the movement from several angles, including general historical studies, geography-specific analyses, biographies of the founder Francis Galton, and explications of the eugenical literature. A complete list of these works would fill a separate paper, but a few titles merit mentioning here.'For a comprehensive history of eugenics in the Anglo-American sphere from the late nineteenth century to the current day, Daniel J. Kevles's In the Name of Eugenics: Genetics and the Uses of Human Heredity (1985) is a valuable study. 2 Kevles devotes his first chapter to Galton and presents a fascinating picture of the thinker's life and personality along with an analysis of his statistical method. The Origins and Growth of the English Eugenics Movement, 1865-1925 (1985), by Lyndsay A. Farrall, has a similar broad scope in its study of the movement, with a chronological focus on pre-World War II times. 3 Ruth Schwartz Cowan's Sir Francis Galton and the Study of Heredity in the Nineteenth Century (1985) places greater emphasis on Galton
