Even the United States Supreme Court endorsed aspects of eugenics. In its infamous 1927 decision, Supreme Court Justice Oliver Wendell Holmes wrote, "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…. Three generations of imbeciles are enough." This decision opened the floodgates for thousands to be coercively sterilized or otherwise persecuted as subhuman. Years later, the Nazis at the Nuremberg trials quoted Holmes's words in their own defense.
Only after eugenics became entrenched in the United States was the campaign transplanted into Germany, in no small measure through the efforts of California eugenicists, who published booklets idealizing sterilization and circulated them to German officials and scientists.
Hitler studied American eugenics laws. He tried to legitimize his anti-Semitism by medicalizing it, and wrapping it in the more palatable pseudoscientific facade of eugenics. Hitler was able to recruit more followers among reasonable Germans by claiming that science was on his side. While Hitler's race hatred sprung from his own mind, the intellectual outlines of the eugenics Hitler adopted in 1924 were made in America.
During the '20s, Carnegie Institution eugenic scientists cultivated deep personal and professional relationships with Germany's fascist eugenicists. In Mein Kampf, published in 1924, Hitler quoted American eugenic ideology and openly displayed a thorough knowledge of American eugenics. "There is today one state," wrote Hitler, "in which at least weak beginnings toward a better conception [of immigration] are noticeable. Of course, it is not our model German Republic, but the United States."
Hitler proudly told his comrades just how closely he followed the progress of the American eugenics movement. "I have studied with great interest," he told a fellow Nazi, "the laws of several American states concerning prevention of reproduction by people whose progeny would, in all probability, be of no value or be injurious to the racial stock."
Hitler even wrote a fan letter to American eugenic leader Madison Grant calling his race-based eugenics book, The Passing of the Great Race his "bible."
Hitler's struggle for a superior race would be a mad crusade for a Master Race. Now, the American term "Nordic" was freely exchanged with "Germanic" or "Aryan." Race science, racial purity and racial dominance became the driving force behind Hitler's Nazism. Nazi eugenics would ultimately dictate who would be persecuted in a Reich-dominated Europe, how people would live, and how they would die. Nazi doctors would become the unseen generals in Hitler's war against the Jews and other Europeans deemed inferior. Doctors would create the science, devise the eugenic formulas, and even hand-select the victims for sterilization, euthanasia and mass extermination.
During the Reich's early years, eugenicists across America welcomed Hitler's plans as the logical fulfillment of their own decades of research and effort. California eugenicists republished Nazi propaganda for American consumption. They also arranged for Nazi scientific exhibits, such as an August 1934 display at the L.A. County Museum, for the annual meeting of the American Public Health Association.
In 1934, as Germany's sterilizations were accelerating beyond 5,000 per month, the California eugenics leader C. M. Goethe upon returning from Germany ebulliently bragged to a key colleague, "You will be interested to know, that your work has played a powerful part in shaping the opinions of the group of intellectuals who are behind Hitler in this epoch-making program. Everywhere I sensed that their opinions have been tremendously stimulated by American thought.…I want you, my dear friend, to carry this thought with you for the rest of your life, that you have really jolted into action a great government of 60 million people."
