It was in December of 1940 that by Dr. Glenn T. Seaborg, Edwin M. McMillan, J. W. Kennedy, and A. C. Wahl initially synthesized and isolated plutonium, and it was first identified in February of 1941. A link can be found below for confirmation and to gather more information.

∙ 13y agoPlutonium was first identified in February of 1941 after Glenn T. Seaborg, Edwin M. McMillan, Joseph W. Kennedy, and Arthur C. Wahl synthesized and isolated it in December of 1940. These investigators worked at the Berkeley Laboratory of the University of California (United States), and made the plutonium via the bombardment of uranium with deuterons. We now create plutonium in nuclear reactors.
