In 1928 Ezra Seymour Gosney founded the non-profit Human Betterment Foundation (HBF) in Pasadena, California to support the research and publication of the personal and social effects of eugenic sterilizations carried out in California. Led by director Gosney and secretary Paul Popenoe, the HBF collected data on thousands of individuals in California who had been involuntarily sterilized under a California state law enacted in 1909. The Foundation's assets were liquidated following Gosney's death in 1942. In 1943, Gosney's daughter donated the remaining assets to the California Institute of Technology (Caltech) in Pasadena, California to establish the Gosney research fund for biological research. Between 1928 and 1942, the HBF published extensively on what they believed to be the benefits of sterilization to both patient and society. The HBF and its members existed within the larger context of the American eugenics movement and scientific institutions, including the Eugenics Record Office at Cold Spring Harbor Laboratory in Cold Spring Harbor, New York, which bolstered the movement's goals of the control of human reproduction and human heredity. Moreover, the model sterilization legislation written by the HBF was disseminated throughout the world to eugenics enthusiasts eager to pass laws limiting the reproduction of people they considered to be unfit.

Cold Spring Harbor Laboratory (CSHL) is a non-profit research institution that specializes in cancer, neuroscience, plant biology, quantitative biology, and genomics. The organization is located on the shores of Cold Spring Harbor in Laurel Hollow, New York. The Brooklyn Institute of Arts and Sciences established the CSHL in 1890, to provide scientists with facilities to research Charles Darwin's evolutionary theory. The first mission of CSHL was biological science education. Since 1998, CSHL has housed the Watson School of Biological Sciences, a PhD program dedicated to scientific research. Nobel Laureates who conducted experiments at the CSHL include Barbara McClintock, Alfred Hershey, James Watson, Francis Crick, and Sydney Brenner. Throughout its history, researchers at CSHL have studied embryology, reproductive medicine, and genetics.

The American Eugenics Society (AES) was established in the US by Madison Grant, Harry H. Laughlin, Henry Crampton, Irving Fisher, and Henry F. Osborn in 1926 to promote eugenics education programs for the US public. The AES described eugenics as the study of improving the genetic composition of humans through controlled reproduction of different races and classes of people. The AES aided smaller eugenic efforts such as the Galton Society in New York, New York, and the Race Betterment Foundation in Battle Creek, Michigan, and it influenced eugenic policy set by the US Supreme Court in cases including Buck v. Bell (1927) and Skinner v. Oklahoma (1942). The AES was renamed the Society for the Study of Social Biology in 1972.

Harry Hamilton Laughlin helped lead the eugenics movement in the United States during the early twentieth century. The US eugenics movement of the early twentieth century sought to reform the genetic composition of the United States population through sterilization and other restrictive reproductive measures. Laughlin worked as superintendent and assistant director of the Eugenics Research Office (ERO) at Cold Spring Harbor Laboratory in Cold Spring Harbor, New York, alongside director Charles Davenport. During Laughlin's career at the ERO, Laughlin studied human familial ancestry, called pedigrees, and in 1922 published the book Eugenical Sterilization in the United States, which influenced sterilization laws in multiple states. Laughlin's support of compulsory sterilization to control the reproductive capacity of entire populations influenced the history of eugenics and reproductive medicine.

Charles Benedict Davenport, Madison Grant, and Henry Fairfield Osborn founded the Galton Society for the Study of the Origin and Evolution of Man, or the Galton Society, in New York City, New York, in 1918. The Galton Society was a scientific society that promoted the study of humans in terms of race in service to the US eugenics movement. The Galton Society was named in honor of Francis Galton who first coined the term eugenics in 1883. Galton and other eugenics proponents claimed that the human species could improve through selective breeding that restricted who could have children. Some of the society members were scientists from a wide range of disciplines who supported the now disproven notion that fundamental biological differences exist between races that may justify the control of human reproduction. The Galton Society drew on the scientific credibility and influence of its members to advocate for eugenics programs, such as immigration restriction laws, in the US.

The International Eugenics Congresses consisted of three scientific meetings held in London, England, in 1912 and at the American Museum of Natural History in New York City, New York, in 1921 and 1932. Leonard Darwin, son of Charles Darwin, Henry Fairfield Osborn, the President of the American Museum of Natural History, and Charles Benedict Davenport, founder of the Eugenics Record Office at Cold Spring Harbor Laboratory in New York City presided over the Congresses. Scientists presented research in genetics and shared ideas for putting eugenics into practice, such as preventing people they considered inferior from reproducing through forced sterilization. The three International Eugenics Congresses increased scientific and public support of the eugenics movement in the early twentieth century, and established organizations to pursue eugenics agendas that contributed to the forced sterilization of hundreds of thousands of people in the US and Nazi Germany.

Charles Benedict Davenport was an early twentieth-century experimental zoologist. Davenport founded both the Station for Experimental Evolution and the Eugenics Record Office at Cold Spring Harbor in New York. Though he was a talented statistician and skilled scientist, Davenport's scientific achievements are eclipsed by his lasting legacy as the scientific leader of the eugenics movement in the US. Eugenics, an attempt to apply genetic science to improve humanity by selective breeding, was a major public health movement in Europe and the United States in the twentieth century prior to World War II. Davenport's involvement in the eugenics movement helped pave the way for the sterilization of tens of thousands of US citizens.
