Madame Marie Curie was a fascinating woman with a passion for science. Under intolerable conditions, she discovered radium and polonium which led to the discovery of x-rays. Her many contributions to science gained her much fame and awards. Her life story is very interesting. You can read it at http://www.nobelprize.org/nobel_prizes/themes/physics/curie/
On a purely foundational level, the Curies were the first to show that atoms were not unchangeable -- that radioactivity was not a chemical reaction but, instead, comes from the element itself. Radium, which the Curies discovered, is a highly radioactive source of alpha particles. It was used in Rutherford's experiment that showed the atom had a nuclear structure. For many decades, radium was also used as a means to kill tumors.
