21-APR-1902 :- Pierre and Marie Curie refine radium chloride.

Radium chloride (RaCl2) is a chemical compound of radium and chlorine, and the first radium compound isolated in a pure state.Marie Curie and André-Louis Debierne used it in their original separation of radium from barium.The first preparation of radium metal was by the electrolysis of a solution of this salt using a mercury cathode.

Marie Skłodowska-Curie ( 7 November 1867 – 4 July 1934) was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and only woman to win twice, the only person to win twice in multiple sciences, and was part of the Curie family legacy of five Nobel Prizes. She was also the first woman to become a professor at the University of Paris, and in 1995 became the first woman to be entombed on her own merits in the Panthéon in Paris.
