Who had the higher IQ?
By the most cited estimates, Werner Heisenberg tops this matchup with an estimated IQ of 180, a 15-point margin over Gregor Mendel (165). 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. Gregor Mendel: —. Werner Heisenberg: Matteucci Medal (1929) • Barnard Medal for Meritorious Service to Science (1930) • Nobel Prize in Physics (1932) • Max Planck Medal (1933) • Foreign Member of the Royal Society (1955) • Foreign Associate of the National Academy of Sciences (1961).
Different eras, different boards
The two were born roughly 79 years apart (1822 vs 1901), 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, Werner Heisenberg 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.
