Although eugenics as understood today dates from the late 19th century, efforts to select matings in order to secure offspring with desirable traits date from ancient times. Platos Republic (c. 378 bce) depicts a society where efforts are undertaken to improve human beings through selective breeding. Later, Italian philosopher and poet Tommaso Campanella, in City of the Sun (1623), described a utopian community in which only the socially elite are allowed to procreate. Galton, in Hereditary Genius (1869), proposed that a system of arranged marriages between men of distinction and women of wealth would eventually produce a gifted race. In 1865 the basic laws of heredity were discovered by the father of modern genetics, Gregor Mendel. His experiments with peas demonstrated that each physical trait was the result of a combination of two units (now known as genes) and could be passed from one generation to another. However, his work was largely ignored until its rediscovery in 1900. This fundamental knowledge of heredity provided eugenicistsincluding Galton, who influenced his cousin Charles Darwinwith scientific evidence to support the improvement of humans through selective breeding.
The advancement of eugenics was concurrent with an increasing appreciation of Darwins account for change or evolution within societywhat contemporaries referred to as social Darwinism. Darwin had concluded his explanations of evolution by arguing that the greatest step humans could make in their own history would occur when they realized that they were not completely guided by instinct. Rather, humans, through selective reproduction, had the ability to control their own future evolution. A language pertaining to reproduction and eugenics developed, leading to terms such as positive eugenics, defined as promoting the proliferation of good stock, and negative eugenics, defined as prohibiting marriage and breeding between defective stock. For eugenicists, nature was far more contributory than nurture in shaping humanity.
During the early 1900s eugenics became a serious scientific study pursued by both biologists and social scientists. They sought to determine the extent to which human characteristics of social importance were inherited. Among their greatest concerns were the predictability of intelligence and certain deviant behaviours. Eugenics, however, was not confined to scientific laboratories and academic institutions. It began to pervade cultural thought around the globe, including the Scandinavian countries, most other European countries, North America, Latin America, Japan, China, and Russia. In the United States the eugenics movement began during the Progressive Era and remained active through 1940. It gained considerable support from leading scientific authorities such as zoologist Charles B. Davenport, plant geneticist Edward M. East, and geneticist and Nobel Prize laureate Hermann J. Muller. Political leaders in favour of eugenics included U.S. Pres. Theodore Roosevelt, Secretary of State Elihu Root, and Associate Justice of the Supreme Court John Marshall Harlan. Internationally, there were many individuals whose work supported eugenic aims, including British scientists J.B.S. Haldane and Julian Huxley and Russian scientists Nikolay K. Koltsov and Yury A. Filipchenko.
Galton had endowed a research fellowship in eugenics in 1904 and, in his will, provided funds for a chair of eugenics at University College, London. The fellowship and later the chair were occupied by Karl Pearson, a brilliant mathematician who helped to create the science of biometry, the statistical aspects of biology. Pearson was a controversial figure who believed that environment had little to do with the development of mental or emotional qualities. He felt that the high birth rate of the poor was a threat to civilization and that the higher races must supplant the lower. His views gave countenance to those who believed in racial and class superiority. Thus, Pearson shares the blame for the discredit later brought on eugenics.
In the United States, the Eugenics Record Office (ERO) was opened at Cold Spring Harbor, Long Island, New York, in 1910 with financial support from the legacy of railroad magnate Edward Henry Harriman. Whereas ERO efforts were officially overseen by Charles B. Davenport, director of the Station for Experimental Study of Evolution (one of the biology research stations at Cold Spring Harbor), ERO activities were directly superintended by Harry H. Laughlin, a professor from Kirksville, Missouri. The ERO was organized around a series of missions. These missions included serving as the national repository and clearinghouse for eugenics information, compiling an index of traits in American families, training fieldworkers to gather data throughout the United States, supporting investigations into the inheritance patterns of particular human traits and diseases, advising on the eugenic fitness of proposed marriages, and communicating all eugenic findings through a series of publications. To accomplish these goals, further funding was secured from the Carnegie Institution of Washington, John D. Rockefeller, Jr., the Battle Creek Race Betterment Foundation, and the Human Betterment Foundation.
Prior to the founding of the ERO, eugenics work in the United States was overseen by a standing committee of the American Breeders Association (eugenics section established in 1906), chaired by ichthyologist and Stanford University president David Starr Jordan. Research from around the globe was featured at three international congresses, held in 1912, 1921, and 1932. In addition, eugenics education was monitored in Britain by the English Eugenics Society (founded by Galton in 1907 as the Eugenics Education Society) and in the United States by the American Eugenics Society.
Following World War I, the United States gained status as a world power. A concomitant fear arose that if the healthy stock of the American people became diluted with socially undesirable traits, the countrys political and economic strength would begin to crumble. The maintenance of world peace by fostering democracy, capitalism, and, at times, eugenics-based schemes was central to the activities of the Internationalists, a group of prominent American leaders in business, education, publishing, and government. One core member of this group, the New York lawyer Madison Grant, aroused considerable pro-eugenic interest through his best-selling book The Passing of the Great Race (1916). Beginning in 1920, a series of congressional hearings was held to identify problems that immigrants were causing the United States. As the countrys eugenics expert, Harry Laughlin provided tabulations showing that certain immigrants, particularly those from Italy, Greece, and Eastern Europe, were significantly overrepresented in American prisons and institutions for the feebleminded. Further data were construed to suggest that these groups were contributing too many genetically and socially inferior people. Laughlins classification of these individuals included the feebleminded, the insane, the criminalistic, the epileptic, the inebriate, the diseasedincluding those with tuberculosis, leprosy, and syphilisthe blind, the deaf, the deformed, the dependent, chronic recipients of charity, paupers, and neer-do-wells. Racial overtones also pervaded much of the British and American eugenics literature. In 1923 Laughlin was sent by the U.S. secretary of labour as an immigration agent to Europe to investigate the chief emigrant-exporting nations. Laughlin sought to determine the feasibility of a plan whereby every prospective immigrant would be interviewed before embarking to the United States. He provided testimony before Congress that ultimately led to a new immigration law in 1924 that severely restricted the annual immigration of individuals from countries previously claimed to have contributed excessively to the dilution of American good stock.
Immigration control was but one method to control eugenically the reproductive stock of a country. Laughlin appeared at the centre of other U.S. efforts to provide eugenicists greater reproductive control over the nation. He approached state legislators with a model law to control the reproduction of institutionalized populations. By 1920, two years before the publication of Laughlins influential Eugenical Sterilization in the United States (1922), 3,200 individuals across the country were reported to have been involuntarily sterilized. That number tripled by 1929, and by 1938 more than 30,000 people were claimed to have met this fate. More than half of the states adopted Laughlins law, with California, Virginia, and Michigan leading the sterilization campaign. Laughlins efforts secured staunch judicial support in 1927. In the precedent-setting case of Buck v. Bell, Supreme Court Justice Oliver Wendell Holmes, Jr., upheld the Virginia statute and claimed, It is better for all the world, if instead of waiting to execute degenerate offspring for crime, or to let them starve for their imbecility, society can prevent those who are manifestly unfit from continuing their kind.
