1. Marie Curie is the only person to have won Nobel Prizes in two different scientific disciplines.

First, Marie Skłodowska Curie won in 1903 for her studies of radioactivity. She shared the prize with her husband, Pierre Curie, and with the other discoverer of radioactivity, Henri Bequerel.

Originally, the Nobel committee had only selected Pierre Curie — but he refused to accept the prize without proper acknowledgement of Marie’s contribution.

Then in 1911, Marie Curie won the Nobel Prize in chemistry for her discovery and studies of radium and polonium.
