Response to @dareinbrocca: "No Marie Curie?"
"Marie Salomea Curie invented the word "radioactivity" in 1896 two years before discovered the elements of polonium and radium. She became the first person to win the Nobel Prize twice, and remains the only person to win it in two different scientific fields: Physics in 1903, and Chemistry in 1911. She also discovered the medical applications of radium in the treatment of cancerous tumors, and she founded and directed the Curie Institute in Paris in 1920 to research that usage, which she chose not to patent so that it could be used to help as many people as possible. Additionally, Marie was the mother of Irène Joliot-Curie, who won a Nobel Prize of her own in Chemistry in 1935 for her discovery of artificial radioactivity the previous year."
