Americium-241 was first identified in 1944 by Seaborg, James and Morgan at the metallurgical laboratory at the University of Chicago. It was produced by the beta-particle decay of plutonium-241, which had been produced in a nuclear reactor by neutron bombardment of plutonium-239. The researchers...
