Who had the higher IQ?
By the most cited estimates, Henri Poincaré tops this matchup with an estimated IQ of 190, a 10-point margin over Marie Curie (180). IQ estimates for historical figures are reconstructions, not test results — they sit on top of biographical evidence, productivity, and the difficulty of the problems each person solved. Treat the number as a directional signal, not a verdict.

Recognition. Henri Poincaré: RAS Gold Medal (1900) • Sylvester Medal (1901) • Matteucci Medal (1905) • Bolyai Prize (1905) • Bruce Medal (1911). Marie Curie: Nobel Prize in Physics (1903) • Davy Medal (1903) • Matteucci Medal (1904) • Elliott Cresson Medal (1909) • Albert Medal (1910) • Nobel Prize in Chemistry (1911) • Willard Gibbs Award (1921) • Cameron Prize for Therapeutics of the University of Edinburgh (1931).
Different eras, different boards
The two were born roughly 13 years apart (1854 vs 1867), which matters: scientific tools, available knowledge, and intellectual culture compound. Comparing minds across eras is comparing players on different boards.
The verdict
So who was greater? The honest answer: they're not strictly comparable. By raw IQ proxy, Henri Poincaré edges out. By measurable, lasting influence in their respective field, both are anchors of the human record. If you have to pick one to bet civilization on, pick the one working on the problem you care about.
