Plutonium was chemically identified in February in 1941 by Glenn T. Seaborg, Edwin M. McMillan, Joseph W. Kennedy, and Arthur C. Wahl at the Berkeley Laboratory of the University of California (United States). They synthesized and isolated it in December of 1940 (not in 1994) after bombarding uranium with deuterons.
