Manhattan Project. Two types of atomic bomb were developed during the war. A relatively simple gun-type fission weapon was made using uranium-235, an isotope that makes up only 0.7 percent of natural uranium. Since it is chemically identical to the most common isotope, uranium-238, and has almost the same mass, it proved difficult to separate. Three methods were employed for uranium enrichment: electromagnetic, gaseous and thermal. Most of this work was performed at Oak Ridge, Tennessee. In parallel with the work on uranium was an effort to produce plutonium. Reactors were constructed at Oak Ridge and Hanford, Washington, in which uranium was irradiated and transmuted into plutonium. The project was also charged with gathering intelligence on the German nuclear energy project. The first nuclear device ever detonated was an implosion-type bomb at the Trinity test, conducted at New Mexico's Alamogordo Bombing and Gunnery Range on 16 July 1945.

American Eugenics Society. The American Eugenics Society (AES) was a society established in 1922 to promote eugenics in the United States. It was the result of the Second International Conference on Eugenics (New York, 1921). The founders included Madison Grant, Harry H. Laughlin, Irving Fisher, Henry Fairfield Osborn, and Henry Crampton. The organization started by promoting racial betterment, eugenic health, and genetic education through public lectures, exhibits at county fairs etc.
Under the direction of Frederick Osborn the society started to place greater focus on issues of population control, genetics, and, later, medical genetics.
