Marie Curie wins a second Nobel Prize

Marie Curie won the Nobel Prize in Physics in 1903, shared with Pierre Curie and Henri Becquerel, and the Nobel Prize in Chemistry in 1911. She remains the only person to win in two different sciences.

Linus Pauling also won two Nobel Prizes, but in chemistry and peace.

Context

The 1903 prize in physics was shared between Marie Curie, Pierre Curie and Henri Becquerel for research on radiation. NobelPrize.org says Pierre insisted that she be included, and she became the first woman to win a Nobel Prize.

In 1911 she received the chemistry prize alone, for isolating radium. She had also discovered polonium, which she named after her native Poland. Both elements were announced in the late 1890s, more than a decade before the chemistry prize.

Both NobelPrize.org and Britannica describe her as the only person to win Nobel Prizes in two different scientific fields. Other people have won more than one Nobel, but not in two separate sciences, which is why the wording matters. The two prizes came eight years apart, in 1903 and 1911, and physics and chemistry are separate Nobel categories.

Linus Pauling won the chemistry prize in 1954 and the peace prize in 1962, and John Bardeen won the physics prize twice, in 1956 and 1972. Neither is a second science: Pauling's peace prize was outside the sciences, and both of Bardeen's prizes were in physics.
