More About Maria Sklodowska-Curie or Marie Curie:
They studied radioactive materials, particularly the ore pitchblende. On December 26, 1898, the Curies announced the existence of an unknown radioactive substance found in pitchblende that was more radioactive than uranium. Over the course of several years, Marie and Pierre processed tons of pitchblende, progressively concentrating the radioactive substances and eventually isolating the chloride salts (radium chloride was isolated on April 20, 1902). They discovered two new chemical elements. "Polonium" was named for Curie's native country, Poland, and "radium" was named for its intense radioactivity.
In 1903, Pierre Curie, Marie Curie, and Henri Becquerel were awarded the Nobel Prize in Physics, "in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena discovered by Professor Henri Becquerel." This made Curie the first woman to be awarded a Nobel Prize.
In 1911 Marie Curie was awarded the Nobel Prize in Chemistry, "in recognition of her services to the advancement of chemistry by the discovery of the elements radium and polonium, by the isolation of radium and the study of the nature and compounds of this remarkable element".
The Curies did not patent the radium isolation process, choosing to let the scientific community freely continue research. Marie Curie died from aplastic anemia, almost certainly from unshielded exposure to hard radiation.
