Marie Curie (1867-1934), Polish-French physicist and chemist. Together with her husband Pierre, Marie isolated the radioactive elements polonium and radium in 1898. Marie won the 1911 Nobel Prize for Chemistry for this work. She had previously been awarded the 1903 Nobel Prize for Physics (with Pierre Curie and Henri Becquerel) for work on radioactivity. She did not take any precautions against the unknown dangers of ionising radiation, and this probably caused her death from leukaemia. Photographed at the Granada Science Park, in Granada, Spain.
