Who had the higher IQ?

By the most cited estimates, Leonhard Euler tops this matchup with an estimated IQ of 190, a 5-point margin over Alan Turing (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.

Recognition. Alan Turing: Smith's Prize (1936). Leonhard Euler: —.

Different eras, different boards

The two were born roughly 205 years apart (1912 vs 1707), 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, Leonhard Euler 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.
