Curium was discovered by Glenn T. Seaborg, Ralph A. James and Albert Ghiorso in 1944 at the University of California, Berkeley.

It was produced by bombarding plutonium with alpha particles during the Manhattan Project.

Curium metal was produced only in 1951 by reduction of curium fluoride with barium. Curium is named after Madame Curie and her husband Pierre Curie 114 1998 Workers at the Nuclear Institute at Dubna, Russia Dubna, Russia Temporary systematic IUPAC nomenclature

Curium is harmful due to its radioactivity
Curium accumulates in the bones, lungs and liver, where it promotes cancer
Curium is mainly used for scientific research purposes.

Curium is a common starting material for the production of higher transuranic elements and transactinides.

The most practical application of 244Cm is as α-particle source in the alpha particle X-ray spectrometers (APXS).
