Pierre Curie was a brilliant physicist in his own right — a pioneer in crystallography, magnetism, and radioactivity research — before he became known primarily as Marie Curie's husband. Together they discovered polonium and radium, shared a Nobel Prize, and built one of the most productive scientific partnerships in history. Then, on a rainy Paris afternoon in 1906, a horse-drawn wagon crushed his skull on the Rue Dauphine.

This episode recovers Pierre from his wife's enormous shadow, examining his independent scientific contributions, the partnership that changed physics and chemistry, and the sudden death that left Marie to carry their work alone.
