Marie Curie is the only person to earn a Nobel prize in two different sciences.

The pioneering researcher won the Nobel Prize in Physics in 1903 (shared with her husband) for her study of spontaneous radiation, and then won the Nobel Prize in Chemistry in 1911 for her work in radioactivity. That makes her one of just six recipients to receive multiple Nobel prizes, and the only person to receive it in two different sciences. (Chemical engineer Linus Paulding earned a Nobel Chemistry Prize and Nobel Peace Prize, but all other multiple winners received theirs in the same category).
