Marie ( 1867–1934), Polish-born French physicist, and Pierre ( 1859–1906), French physicist, pioneers of radioactivity. Working together on the mineral pitchblende, they discovered the elements polonium and radium, for which they shared the 1903 Nobel Prize for Physics with A.-H. Becquerel. After her husband’s accidental death Marie received another Nobel Prize (for chemistry) in 1911 for her isolation of radium. She died of leukaemia, caused by prolonged exposure to radioactive materials.
