Irène Joliot-Curie (September 12, 1897 – March 17, 1956)
She worked primarily with her husband, Frédéric Joliot-Curie, on radioactive elements. In 1935, they were awarded the Nobel Prize in Chemistry for the discovery of artificially-produced radioactive isotopes. Their discovery meant that those involved in nuclear physics and medicine would not have to undergo the tedious task of attempting to separate the radioactive elements necessary for their work. As her sister Eve said of Irène, "Her sincere love of science, her gifts, inspired in her only one ambition: to work forever in that laboratory which she had seen go up."
That one must do some work seriously and must be independent and not merely amuse oneself in life—this our mother [Marie Curie] has told us always, but never that science was the only career worth following.
