Who had the higher IQ?
By the most cited estimates, Max Planck tops this matchup with an estimated IQ of 190, a 5-point margin over James Clerk Maxwell (185). 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
James Clerk Maxwell is best known for: Statistical mechanics • Maxwell's equations • Displacement current • Maxwell relations Max Planck is best known for: On the Second Principles of Mechanical Heat Theory (1879)
Recognition. James Clerk Maxwell: FRSE • FRS • Smith's Prize (1854) • Adams Prize (1857) • Rumford Medal (1860) • Keith Prize (1869–71). Max Planck: Nobel Prize in Physics (1918) • Foreign Associate of the National Academy of Sciences (1926) • Lorentz Medal (1927) • Copley Medal (1929) • Max Planck Medal (1929) • Goethe Prize (1945).
Different eras, different boards
The two were born roughly 27 years apart (1831 vs 1858), 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, Max Planck 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.
