Bernhard Riemann vs Henri Poincaré
Bernhard Riemann (IQ 180) vs Henri Poincaré (IQ 190). Side-by-side comparison of intellect, achievements, era and cultural impact.
| Born | 1826 | 1854 |
|---|---|---|
| Died | 1866 | 1912 |
| Country | DE | FR |
| Estimated IQ | 180 | 190 |
| Best known for | Riemann–von Mangoldt formula, Riemann bilinear relations, Cauchy–Riemann equations, Free Riemann gas, Pseudo-Riemannian manifold, Riemann's differential equation | Poincaré conjecture |
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 Bernhard Riemann (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.
Achievements compared

Different eras, different boards
The two were born roughly 28 years apart (1826 vs 1854), 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.
