As a poor student in Paris, Marie Curie piled clothes --- and furniture --- on top of herself to keep warm at night. But Marie went on to become the first woman to win a Nobel Prize --- and also the first person to win this award twice. Marie Curie's discoveries in radiation changed the world. She became one of the most important women in science and her research is still important to scientists and doctors today. Radiation is used as a treatment for cancer and to produce electricity, kill organisms that spoil food and detect smoke in homes. This book in the Snapshots: Images of People and Places in History series introduces one of the most important women in science and her inspiring life.
