Madame Curie shared her 1903 Nobel Prize in Physics with her husband Pierre Curie and with physicist Henri Becquerel. She was the sole winner of the 1911 Nobel Prize in Chemistry. Her achievements included a theory of radioactivity (a term that she coined), techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium. Under her direction, the world’s first studies were conducted into the treatment of neoplasms, using radioactive isotopes.
