Who was the first person to win Nobel Prizes in two different sciences?

Marie Curie was the first person to win Nobel Prizes in two different sciences.

Curie won the 1903 Nobel Prize in Physics for research into radiation, sharing it with Pierre Curie and Henri Becquerel. In 1911, she won the Nobel Prize in Chemistry for discovering the elements polonium and radium, isolating radium, and studying its properties. She remains the only person to win Nobel Prizes in two different scientific fields.

Born Maria Skłodowska in Warsaw in 1867, she moved to Paris to study at the Sorbonne. Her work helped establish the scientific study of radioactivity, a term she introduced. During World War I, she promoted mobile X-ray units that helped doctors treat wounded soldiers.

Curie's laboratory notebooks remain radioactive more than a century later, so they are stored with special precautions. Her daughter Irène Joliot-Curie later won the 1935 Nobel Prize in Chemistry, making the family one of science's most distinguished.
