Marie Curie (1867-1934) was the first woman to win a Nobel Prize in physics and chemistry. Together with her husband Pierre Curie, she discovered the chemical elements polonium and radium. Marie Curie is the only woman to have been awarded a Nobel Prize several times and, along with Linus Pauling, the only person to have received Nobel Prizes in two different fields.
