Property	Data	Remarks
Named for:	Pierre Curie (1859-1906), French physicist and 1903 Nobel Laureate in Physics, together with his wife, Marie Curie (née Maria Sklodowska) (1867 - 1934) (who additionally won the Nobel Prize for Chemistry in 1911), and Henri Becquerel, for research into the nature of radioactivity Some sources also list Marie Curie as being the co-honoree for this mineral's name.
