Who had the higher IQ?

By the most cited estimates, Paul Dirac tops this matchup with an estimated IQ of 190, a 10-point margin over Stephen Hawking (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.

Recognition. Paul Dirac: Nobel Prize in Physics (1933) • Royal Medal (1939) • Copley Medal (1952) • Max Planck Medal (1952) • Fellow of the Royal Society (1930). Stephen Hawking: Adams Prize (1966) Eddington Medal (1975) Maxwell Medal and Prize (1976) Heineman Prize (1976) Hughes Medal (1976) Albert Einstein Award (1978) Albert Einstein Medal (1979) RAS Gold Medal (1985) Dirac Medal (1987) Wolf Prize (1988) Prince of Asturias Award (1989) Foreign Associate of the National Ac.

Different eras, different boards

The two were born roughly 40 years apart (1902 vs 1942), 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, Paul Dirac 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.
