Marie Curie

Marie Curie (1867-1934)

Marie Curie is best known for her discovery of radium. She shared the 1903 Nobel Prize in physics with her husband, Pierre, and Henri Becquerel for their pioneering work on radioactivity. Madame Curie is one of the few who ever won two Nobel Prizes -- one in Physics and one in Chemistry.

Not surprisingly, Marie Curie died of leukemia caused by an extreme exposure to radioactivity at a time when its dangers were not known.
