Antoine Lavoisier IQ
Chemist · 1743–1794
Quick Answer
Antoine Lavoisier's IQ is estimated at 150 to 170. Cox's 1926 study gave him a corrected 170; no test was ever taken.
Cox's corrected estimate was 170. Lavoisier turned chemistry into a quantitative science, and that record is well documented.

Evidence status: Low confidence. Lavoisier died in 1794. No test exists; the figure below is from a 1926 study of biographies. Historical achievement cannot be converted into a precise modern test result. This page separates documented evidence from interpretation.
What was Antoine Lavoisier's 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.
Why was Lavoisier executed?
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.
Where does the 170 figure come from?
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.
How smart was Antoine Lavoisier?
Conservation of mass
Careful weighing showed that matter is neither created nor destroyed in chemical reactions.
Explaining fire
He showed that burning is combination with oxygen, ending the phlogiston theory.
Naming the elements
He named oxygen and hydrogen and co-created the system of chemical names still used.
The first modern textbook
His 1789 Traité élémentaire de chimie listed elements and set chemistry on a new footing.
How Lavoisier thought
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.
Evidence behind the Antoine Lavoisier IQ estimate
The estimate is a structured interpretation of the record, not a recovered test score. These are the strongest signals and the reasons for caution.
Evidence considered
- 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 the estimate 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.

Take the Lavoisier IQ test
Antoine Lavoisier's estimate is 150+. Our Einstein IQ test is a short visual reasoning challenge. See which side of that number you land on.
Take the Lavoisier IQ testAntoine 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.
Psychological Profile
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.
Key Behavioral Traits
He built expensive, precise instruments, funded by his tax-farming income.
He worked closely with his wife Marie-Anne, who translated and illustrated his work.
He also worked on public projects such as street lighting and gunpowder.
One thing most people do not know
Marie-Anne Lavoisier learned English to translate British chemistry papers for him and drew the plates in his textbook.

Antoine Lavoisier: People Also Ask
Was Antoine Lavoisier a genius?+
Antoine's record supports exceptional achievement, but "genius" is not established by an unverified IQ number. Their The Scholar archetype, combined with Measurement and Systematic Thinking, is a more useful interpretation of their output.
What personality type was Antoine Lavoisier?+
Antoine fits the The Scholar archetype. Key traits include Measurement, Systematic Thinking, and Organisation. This profile helps explain both their strengths and their documented failure modes.
What can we learn from Antoine Lavoisier?+
Antoine's profile teaches that extreme strengths create extreme trade-offs. Their Measurement and Systematic Thinking enabled success but also created recurring friction.
