Marie Curie
Marie Curie (1867–1934), born Maria Skłodowska in Warsaw, was a physicist and chemist whose work on radioactivity transformed science. Together with her husband Pierre, she isolated the elements polonium and radium, and shared the 1903 Nobel Prize in Physics with Henri Becquerel. In 1911 she received a second Nobel Prize, in Chemistry — the first person to be awarded the prize twice. She was also the first woman to hold a professorship at the Sorbonne.
