1903: Physics, shared — for work on radioactivity. 1911: Chemistry, alone — for radium and polonium, and the isolation of radium. The medals are symbols. The real story is years of crushing ore, measuring, and refusing to quit when the work was heavy and the recognition uneven.

Power listens in many tongues. I ruled a Greek dynasty in an Egyptian land under Rome's shadow. Diplomacy begins before the treaty: in the language you choose, the respect you signal, the story you refuse to let others write for you.
