The only person ever to win Nobel Prizes in two different sciences

Marie Curie shared the 1903 Nobel Prize in Physics for discovering radioactivity, then won the 1911 Nobel Prize in Chemistry outright for isolating pure radium and polonium. No one else has won Nobel Prizes in two different scientific fields. She did it while raising two daughters and eventually died from her decades of unshielded exposure to the radioactive materials she pioneered studying.
