Pierre and Marie Curie refine radium chloride.

Pierre Curie was a French physicist and chemist, and a pioneer in crystallography and magnetism. He shared one half of the 1903 Nobel Prize in Physics with his wife, Maria Skłodowska-Curie, for their work on radioactivity. With their win, the Curies became the first married couple to win a Nobel Prize, launching the Curie family legacy of five Nobel Prizes.
