First Isolation of Plutonium-238 in Berkeley

Researchers at the University of California, Berkeley, managed to isolate plutonium-238, a significant isotope, on December 14, 1940. This was achieved by a team led by Glenn T. Seaborg, who utilized nuclear reactions involving uranium to produce and subsequently identify this new element. Their work was pivotal in advancing nuclear chemistry and physics, laying the groundwork for future developments in both research and nuclear energy applications.
