who discovered americium

Americium was discovered in 1944 by a group of scientists that included Glenn T. Seaborg, Ralph A. James, Leon O. Morgan, and Albert Ghiorso. The discovery took place at the Metallurgical Laboratory of the University of Chicago as part of the Manhattan Project. The element was first produced by bombarding plutonium isotopes with neutrons in a nuclear reactor, and it was chemically identified through a complex separation process. The discovery was kept secret during World War II and was publicly announced by Glenn Seaborg in November 1945 on a children's radio show called "Quiz Kids".
