Marie Curie was Polish-born physicist and chemist who isolated radium and polonium from pitchblende. She shared 1903 Nobel in Physics for radioactivity research with Pierre Curie and Becquerel. She won 1911 Nobel in Chemistry for discovering radium and polonium. Curie coined the term radioactivity. She processed tonnes of pitchblende to isolate 1/10 gram of radium chloride by 1902. Curie founded Radium Institutes in Paris and Warsaw. She developed mobile X-ray units treating over a million WWI soldiers. Pierre Curie died in 1906 street accident. Curie became first woman professor at University of Paris. She never patented radium isolation to aid science. Curie died in 1934 from radiation-induced aplastic anemia. Her papers remain too radioactive to handle without protection. Curie overcame sexism barring women from universities. She named polonium after Poland. Her family legacy includes five Nobel Prizes. Curie rejected Legion of Honour. She endured 1911 affair scandal with Paul Langevin.
