Who had the higher IQ?

By the most cited estimates, Henri Poincaré tops this matchup with an estimated IQ of 190, a 0-point margin over Paul Dirac (190). 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). Paul Dirac: Nobel Prize in Physics (1933) • Royal Medal (1939) • Copley Medal (1952) • Max Planck Medal (1952) • Fellow of the Royal Society (1930).

Different eras, different boards

The two were born roughly 48 years apart (1854 vs 1902), 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.
