In 1891, 24-year-old Marie Sklodowska moved from Warsaw to Paris, where she found work in the laboratory of Pierre Curie, a scientist engaged in research on heat and magnetism. They fell in love. They took their honeymoon on bicycles. They expanded the periodic table, discovering two new elements with startling properties, radium and polonium. They recognized radioactivity as an atomic property, heralding the dawn of a new scientific era. They won the Nobel Prize. Newspapers mythologized the couple's romance, beginning articles on the Curies with "Once upon a time . . . " Then, in 1906, Pierre was killed in a freak accident. Marie continued their work alone. She won a second Nobel Prize in 1911, and fell in love again, this time with the married physicist Paul Langevin.
