Marie Curie, a pioneering physicist and chemist, died in 1934 from aplastic anemia, a condition likely caused by prolonged exposure to radiation during her groundbreaking research on radioactivity. She was a two-time Nobel laureate, receiving the Nobel Prize in Physics in 1903 with her husband Pierre Curie and Henri Becquerel, and the Nobel Prize in Chemistry in 1911 for her discovery of polonium and radium. Curie's legacy is cemented by her pioneering work in radioactivity, which revolutionized our understanding of the atom and led to the development of medical treatments using radiation. Her dedication to science came at a personal cost, as she unknowingly exposed herself to harmful levels of radiation throughout her career.
