Bernhard Riemann vs Pierre de Fermat
Bernhard Riemann (IQ 180) vs Pierre de Fermat (IQ 175). Side-by-side comparison of intellect, achievements, era and cultural impact.
| Born | 1826 | 1607 |
|---|---|---|
| Died | 1866 | — |
| Country | DE | FR |
| Estimated IQ | 180 | 175 |
| Best known for | Riemann–von Mangoldt formula, Riemann bilinear relations, Cauchy–Riemann equations, Free Riemann gas, Pseudo-Riemannian manifold, Riemann's differential equation | Fermat's Last Theorem |
Who had the higher IQ?
By the most cited estimates, Bernhard Riemann tops this matchup with an estimated IQ of 180, a 5-point margin over Pierre de Fermat (175). 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
Bernhard Riemann is best known for: Riemann–von Mangoldt formula, Riemann bilinear relations, Cauchy–Riemann equations, Free Riemann gas, Pseudo-Riemannian manifold, Riemann's differential equation Pierre de Fermat is best known for: Fermat's Last Theorem
Different eras, different boards
The two were born roughly 219 years apart (1826 vs 1607), 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, Bernhard Riemann 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.
