Maria Skłodowska-Curie, ca. 1898. Portrait of Maria Skłodowska-Curie (November 7, 1867 – July 4, 1934), sometime prior to 1907. Curie and her husband Pierre shared a Nobel Prize in Physics in 1903. Working together, she and her husband isolated Polonium. Pierre died in 1907, but Marie continued her work, namely with Radium, and received a Nobel Prize in Chemistry in 1911. Her death is mainly attributed to excess exposure to radiation. via @wikipedia
