History

History
The element Curium was discovered by Glenn T. Seaborg in year 1944 in United States. Curium derived its name from from Pierre Curie, a physicist, and Marie Curie, a physicist and chemist, named after great scientists by analogy with gadolinium
The element Mendelevium was discovered by Lawrence Berkeley National Laboratory in year 1955 in United States. Mendelevium derived its name derived its name from from Dmitri Mendeleev, chemist and inventor
