Marie Curie (1867–1934) was a Polish and naturalized-French physicist and chemist. Her groundbreaking research on radioactivity led to the discovery of two elements, polonium and radium, earning her two Nobel Prizes in physics (1903) and in chemistry (1911), becoming the first person and only woman to achieve such a feat. Her work revolutionized understanding of atomic structure and radiation, laying the foundation for modern nuclear physics and medical radiation therapy. This photograph of Curie was taken around the 1920s.Photograph credit: Henri Manuel; restored by FMSky and Bammesk
