Historia
Nobelium was discovered by Albert Ghiorso, Glenn T. Seaborg, John R. Walton and Torbjørn Sikkeland in 1958 at the University of California, Berkeley.

It was produced by the bombardment of curium with carbon atoms.

It was correctly identified in 1966 by scientists at the Flerov Laboratory of Nuclear Reactions in Dubna, Soviet Union.
