Marie Sklodowski Curie, 1867-1934 As December is a month for gift-giving, it is a suitable time to look at Marie Curie whose research resulted in gifts of knowledge that continue to impact the whole world. Madame Curie, as she is most frequently called, was a self-effacing woman who lived for her research and her family. She was the first woman to receive a Nobel Prize (1903 in Physics for the discovery of radioactivity), and only one of four individuals to have ever received two Nobel Prizes (the second in 1911 in Chemistry for the discovery of radium and polonium and for the chemical isolation of pure radium). Marie's discovery of radium gave birth to understanding of the structure of the atom. Her methods of research pioneered a meticulous pursuit of knowledge that immensely improved the image of science. Her research, which has led to radiation treatment to help cancer patients, caused her own death by "radiation poisoning"--doctors labeled it "aplastic pernicious anemia of rapid, feverish development." Actually, it had not been a rapid development, and the anemia was likely a form of leukemia caused by years of unprotected contact with radioactivity. marie curie • madame curie • radioactivity • radium • research
