Who has the highest IQ?
Intelligence is the type of thing that seems like it would be difficult to measure, and the truth is, it is. But that hasn’t stopped us from being fascinated by intelligence tests that attempt to assign a numerical value to how smart we are—and trying to figure out who has the highest IQ in the world.
While there is no “standard” intelligence quotient (IQ) test, the scoring tends to be similar across the various versions, with 100 being considered an “average” IQ and anything 140 or above considered genius territory. And though new tests and revisions of existing tests have come and gone over the years, there are a handful that are most commonly used today, including the Wechsler Adult Intelligence Scale, Stanford-Binet Intelligence Scale, and Peabody Individual Achievement Test. In addition to the tests, there are many different types of intelligence itself, including emotional, musical, visual-spatial, naturalistic, and linguistic-verbal.
This is all to say that we should take a person’s IQ scores with a grain (or a pound) of salt—yes, even Albert Einstein’s. In fact, though his IQ is commonly cited as being 160, that’s just an estimate; it’s unlikely that he ever took an IQ test during his lifetime. In fact, given that IQ tests are relatively recent inventions, there is no way of definitively knowing who has the highest IQ of all time.
All of those caveats aside, here are 35 people with IQs (either based on testing or an estimate) higher than Einstein’s. And if you want to put your own mind to the test, here are some brain games, brain teasers, and a Mensa IQ test to get you started.

Jacob Barnett: IQ 170
Jacob Barnett was diagnosed with moderate to severe autism at two years old, and doctors predicted he’d never learn to tie his own shoes. Needless to say, he’s mastered that task. The American child prodigy finished grades 6 through 12 in less than a year, then went to college at age 10. He was a published physicist by the time he was 13. Now he’s 21 and working toward his PhD.

Rick Rosner: IQ 192–198
Rick Rosner has taken more than 30 IQ tests, revealing his IQ is between 192 and 198, depending on how the tests define their scores. Before the allegedly second-smartest man in the world became a TV writer, he worked as a bouncer, stripper, and nude model. He famously sued the ABC network for a faulty question after losing Who Wants to Be a Millionaire? at the $16,000 level, but lost the case.

Nathan Leopold: IQ 200
The infamous Nathan Leopold had an IQ of 200 and spoke nine languages by age 18, but he didn’t use his intelligence for the greater good. When he was 19, he and an accomplice were arrested for murder in 1924 after trying to commit the “perfect crime”—you know, the type of crime that never gets solved. Leopold spent 33 years in jail before being released on parole. He died in 1971.

Marilyn vos Savant: IQ 228
When Marilyn vos Savant was 10 years old, an adult-level Stanford-Binet test revealed she had an IQ of 228, which later landed her a Guinness World Record until the company removed the category in 1990 because the numbers are considered inexact. She’s been answering philosophical and mathematical questions for Parade magazine readers in her “Ask Marilyn” column since 1986.
This former Irish child genius, who’s now 21, is projected to have an IQ of 263. At eight years old, he was already taking third-year chemistry courses at Singapore Polytechnic, and by the time he was nine, he’d memorized the first 518 decimal places of pi. He also seems to have a knack for entertainment, having written the script and composed music for a short film called Reflection at age 12.

Johann Goethe: IQ 210–225
When American electrochemical engineer Libb Thims set out to find the person with the highest IQ in history, he did so using a methodology that predicts a person’s IQ based on how much they accomplished every 10 years of their life. This came in handy when attempting to rank people who themselves predated IQ tests. Based on his own approach, Thims estimated that German Renaissance man Johann Goethe was the person with the highest IQ of all time, with a score ranging from 210 to 225. While typically labeled as a philosopher, Goethe was also an accomplished scientist and poet.

Routinely referred to as “the smartest man in America,” Christopher Langan is a former cowboy, current horse rancher, and an independent researcher and reality theorist. One of his signature works is his Cognition-Theoretic Model of the Universe, which he refers to as “the CTMU” and says is pronounced cat-mew. In a 2007 interview with Esquire, Langan told the magazine that it was “a true ‘Theory of Everything,’ a cross between John Archibald Wheeler’s ‘Participatory Universe’ and Stephen Hawking’s ‘Imaginary Time’ theory of cosmology.”

Adragon De Mello: IQ 400
In 1988, when Adragon De Mello graduated from the University of California, Santa Cruz, with a degree in computational mathematics at the age of 11, he was the youngest college graduate in the United States (a record he no longer holds). Though he was reported to have a projected IQ of 400, De Mello hasn’t been in the public eye much in the past 20 years. We do know that in 2001, when he was a 24-year-old “high-tech worker,” he took custody of his father who was dying of bladder cancer.

Leonardo da Vinci: IQ 180–220
While IQ tests weren’t around when Leonardo da Vinci was, it is now estimated that his score would have been between 180 and 220. This makes sense when you think about it: With skills ranging from artand science to music and architecture, da Vinci didn’t just work in different fields—he excelled at them. In fact, he was so ahead of his time that many of his inventions (like flying machines, the telescope, and the submarine) didn’t come to fruition until long after his death. Find out thesecret messages he hid in his paintings.

Isaac Newton: IQ 190–200
Sir Isaac Newton is another example of a scientist—in this case, a physicist—far ahead of his time. Though he’s best known for his universal principles of gravity, the 17th-century thinker was also a mathematician, astronomer, and writer. It is estimated that his IQ score would fall between 190 and 200, depending on the measures used. Fun fact: Isaac Newton was one of the geniuses who made history in quarantine.

Nicolaus Copernicus: IQ 160
Polish astronomer and mathematician Nicolaus Copernicus may have had an estimated IQ score ranging from 160 to 200, but his ideas weren’t always the most popular. For example, the Catholic Church banned his book De Revolutionibus Orbium Coelestium (On the Revolutions of the Celestial Spheres) for more than two centuries. In it, he put forth the heliocentric model of the universe, which places the sun—and not Earth—at the center of the solar system. Looking to expand your own mind? Here are 24 astronomy facts you never learned in school.
Somehow, Kim Ung-Yong has been dubbed both a “failed genius” and the person with the highest IQ of all time.

Known for his ability to solve complex mathematical equations at the age of four, Ung-Yong was invited to work for NASA when he was eight years old. Though he worked there for a decade, he ultimately left the position because he was lonely, he told The Korea Herald in 2010.

Nikola Tesla: IQ 160–310
Nikola Tesla, the Serbian-American inventor—and arch-rival of Thomas Edison—reportedly had an estimated IQ falling somewhere between 160 and 310, depending on the measure. Though he’s responsible for dreaming up (and, in some cases, creating) a wide range of new technologies, Tesla is best known for inventing the first alternating current (AC) motor and developing AC generation and transmission technology. In the final years of his life, Tesla’s mental health deteriorated, and he died alone in the New York hotel room where he’d resided.
