The Eugenics Record Office (ERO), located in Cold Spring Harbor, New York, United States, was a research institute that gathered biological and social information about the American population, serving as a center for eugenics and human heredity research from 1910 to 1939. It was established by the Carnegie Institution of Washington's Station for Experimental Evolution, and subsequently administered by its Department of Genetics. Both its founder, Charles Benedict Davenport, and its director, Harry H. Laughlin, were major contributors to the field of eugenics in the United States. Its mission was to collect substantial information on the ancestry of the American population, to produce propaganda that was made to fuel the eugenics movement, and to promote the idea of race-betterment. History The eugenics movement was popular and viewed as progressive in the early-twentieth-century United States. Charles Davenport was one of the leaders of this campaign and avidly believed that it was necessary to apply Mendelian Genetics principles to humans. Davenport's wife, Gertrude Davenport, was also an important figure in this movement and the establishment of the ERO. Gertrude Davenport was an embryologist and a geneticist who wrote papers with her husband supporting the idea that Mendelian genetics theories applied to humans. Supported by the argument that the eugenics office would collect information for human genetics research, Davenport convinced the Carnegie Institute to establish the ERO. He was well connected to wealthy people during the time and he lobbied them to finance his vision of the ERO. The ERO was financed primarily by Mary Harriman (widow of railroad baron E. H. Harriman), the Rockefeller Foundation, and then the Carnegie Institution until 1939. In 1935 the Carnegie Institution sent a team to review the ERO's work, and as a result the ERO was ordered to stop all work. In 1939 the Carnegie Institution's new President, Vannevar Bush, forced Laughlin's retirement and withdrew funding for the ERO entirely, leading to its closure at the end of that year. Superintendent Harry H. Laughlin, formerly a school superintendent in Iowa, held a position akin to that of an assistant director of the ERO. Charles Davenport appointed Laughlin as a head of the ERO due to Laughlin's extensive knowledge about breeding and the implementation of this knowledge in humans. Under the direction of Laughlin, the ERO advocated laws that led to the forced sterilization of many Americans it categorized as 'socially inadequate'. The endeavors of the Eugenics
