Antoine Lavoisier IQ

Lavoisier never took an IQ test. Catharine Cox's 1926 study gave him a corrected estimate of 170. Adjusted for the Flynn effect that is about 150, so LifeScore uses a range of 150 to 170 for the man who turned chemistry into a science of measurement.

Lavoisier was guillotined in 1794 because he had been a tax farmer, a private collector of royal taxes, not because of his science. The mathematician Joseph-Louis Lagrange reportedly said it took only an instant to cut off that head, and a century might not produce another like it.

The 170 is Catharine Cox's corrected estimate from her 1926 study of 301 eminent people born between 1450 and 1850. She rated each person from biographical records of what they could do as a child and young adult, then corrected for gaps in the record.

Cox's numbers sit on an old ratio-IQ scale. One secondary tabulation subtracts about 22 points for the Flynn effect, which puts Antoine Lavoisier near 150.

LifeScore lists 150+, and the working range of 150 to 170 spans both figures. None of them is a test result.

Lavoisier trusted the balance. If mass seemed to vanish or appear, something had been missed, so he built sealed experiments to catch every gas. That insistence on accounting turned alchemy's leftovers into chemistry.

What supports it

• Cox's 1926 study gave Lavoisier a corrected estimate of 170, about 150 after a Flynn-effect adjustment.
• His careful weighing showed that mass is conserved in chemical reactions.
• He named oxygen and hydrogen and replaced the phlogiston theory with a modern account of combustion.

What it cannot prove

• Much of his lab work was shared with Marie-Anne Paulze Lavoisier and other collaborators.
• He was executed at 50, cutting short the record.
• Cox's scale runs higher than modern deviation IQ.

Antoine Lavoisier's IQ is represented here by a retrospective estimate of 150+, not a verified test result. Antoine Lavoisier is best known for exceptional measurement. The useful question is what the surviving evidence shows, not whether a precise modern score can be recovered.

Systematic and quantitative. Weighed everything and trusted the balance.

The dominant archetype here is The Scholar. This archetype shapes decision patterns: what feels natural, what creates friction, and what blind spots tend to emerge.

Estimated IQ is 150+. This is a rough estimate based on documented accomplishments and contemporary accounts, not a literal measurement.

Marie-Anne Lavoisier learned English to translate British chemistry papers for him and drew the plates in his textbook.

Antoine Lavoisier's estimate of 150+ falls in the genius level IQ range. See what an IQ of 150 means, place it on the IQ chart or check how rare it is with the IQ rarity calculator.
