Glenn T. Seaborg did not make californium himself; it was discovered by a research team at the University of California in 1950. The element was first synthesized by bombarding curium-242 with alpha particles to produce californium-245. Seaborg played a key role in the discovery and identification of californium, as well as in its naming after the state of California.
Californium is a radioactive element that is not found naturally under 'normal' circumstances. It was created in a laboratory in University of California, Berkeley by physicists Stanley G. Thompson, Albert Ghiorso, Kenneth Street Jr. and Glenn T. Seaborg in March 17 of 1950. It was named Californium because of the place of discovery.
