Information trouvée : Harry Hamilton Laughlin, a son of George Hamilton and Deborah Jane Laughlin, was born
at Oskaloosa, Iowa, on March 11, 1880,Dr. Laughlin was a prolific writer, publishing
numerous articles and books on eugenics, eugenical sterilization, immigration, genetics,
and various phases of inheritance including racing capacity in thoroughbred horses.
It is his work on eugenical sterilization and immigration restriction for which he
is best known. Laughlin's Eugenical Sterilization in the United States established
him as an expert on the topic. His model sterilization laws were used by many of the
more than 30 states that passed sterilization laws. Germany's 1933 sterilization laws
were also modeled after Laughlin's. Laughlin's immigration studies, which seemed to
support the idea that recent immigrants from Southern and Eastern Europe had a higher
percentage of "socially inadequate" persons than other immigrants, led to the highly
restrictive immigration quota system of 1924 which favored immigrants from Northern
Europe. As is evident in the Laughlin Collection, Dr. Laughlin also devoted considerable
time and effort developing his ideas for a common world government...After his retirement
from the Eugenics Record Office they returned to Kirksville in December 1939. Dr.
Laughlin died January 26, 1943,
