Marie Curie, a Polish-born physicist and chemist, is credited with the discovery of radium and polonium. Alongside her husband, Pierre Curie, she conducted groundbreaking research on radioactivity, leading to their discovery of these two elements. Marie Curie’s pioneering work in the field of radioactivity earned her the distinction of being the first woman to win a Nobel Prize and the only person to win Nobel Prizes in two different scientific fields (Physics and Chemistry). Her contributions to science have had a lasting impact on the fields of physics and chemistry, solidifying her legacy as one of the most influential scientists in history.
