Marie Curie is perhaps the most famous female scientist in history. Despite facing both ethnic and gender bias, she received her doctorate at the Sorbonne and forged a career as a pioneer in physics, specifically in the field of radiation research. Together with her husband, Pierre, she discovered the elements of radium and polonium. This discovery earned the couple the Nobel Prize in Physics in 1903. Marie Curie also later earned a second prize, for Chemistry in 1911, on her own. This biography explores her life.
