Dr. Irène Joliot-Curie, a French physicist and chemist, is best known for her work on radioactivity and nuclear physics. She grew up helping her mother run radiology units in field hospitals during World War I, and in 1925, she attained her Doctorate of Science for her thesis on the radiation of polonium. She and her husband discovered how to artificially manufacture radioactive atoms, which are crucial to cancer treatment and biomedical research. In 1935, they shared the Nobel Prize in Chemistry for their work on the synthesis of new radioactive elements. She lived the rest of her life advocating for international peace and women’s rights.
