Nobelium was discovered by Nobel Institute of Physics in Stockholm and later by Albert Ghiorso, Torbjorn Sikkeland, J. R. Walton, and Glenn T. Seaborg (US) in 1958. Named in honour of Alfred Nobel, Swedish chemist who discovered dynamite and founder of the Nobel Prizes. It is a synthetic radioactive metal. Nobelium was made by bombarding curium with carbon-13
