Harry Hamilton Laughlin (1880-1943)

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.
