One Universe at a Time

Marie Skłodowska-Curie was a pioneer in the study of radioactivity. She in fact coined the term. She developed a method for isolating radioisotopes, and discovered two elements (radium and polonium). She worked on radiation therapy of tumors, and developed established military radiological centers during World War I. She is the only person ever to have won a nobel prize in two scientific fields (Physics in 1903, and Chemistry in 1911). She also happened to be the mother of two daughters.
