All of us are familiar with the term ‘IQ’ and have come across it in various phases of life, mostly in schools and colleges. The toppers of our class were called by names like ‘geeks’ and ‘people having high IQ levels’. So what exactly is meant by IQ? It is actually the marks scored by a person in any of the standard tests meant to measure the individual’s intelligence level.

Intelligence Quotient or IQ can be determined on the basis of numerous factors including the social status of parents, morality, IQ of parents, morbidity and more. A lot of different methods are being used to examine a person’s IQ level. These include but not limited to abstract reasoning problems, verbal tests, visual tests and other tests related to general awareness, vocabulary, reading, and arithmetic.

Though not the single measure of one’s intellect, IQ is considered to be the most popular method of testing a person’s intelligence. The general IQ score of the majority of the population falls between 70 to 130. Only 1 out of 200 people score more than 140. That said, all of us would want to know who are the people with the highest IQ recorded. Here is a list of the smartest people across the world whose levels of IQ have made records in the history.

Personalities With Highest IQ Recorded

10. Stephen Hawking (IQ: 160)

Stephen Hawking - highest IQ

It is good to start the list with one of the most regarded theoretical physicists of all time, Stephen Hawking. Professor Hawking is the author of ‘A Brief History of Time’, one of the most popular works regarding the Big Bang Theory. His topics of work were the fundamental laws governing the universe. He possesses twelve honorary degrees. He has received numerous prizes, medals, and awards and is a member of the US National Academy of Sciences and a Fellow of The Royal Society.

When Hawking was just 12 years, he was diagnosed with a serious disease called Amyotrophic Lateral Sclerosis (ALS) which had paralyzed him to a great extent. In this syndrome, the patients die within five years but Hawking is currently alive and moves around. His brain was recorded with an IQ of 160 which left the entire world in surprise. He has contributed greatly in an important area of physics, general relativity. This paralyzed man with one of the highest IQ recorded proved to the world that achievements and dreams have nothing to do with physical conditions. He is an author, theoretical physicist, and cosmologist. He is the Director of Research at the Cambridge Center for Theoretical Cosmology.

9. Sir Andrew Wiles (IQ: 170)

Sir Andrew Wiles - high IQ

Ranking at the ninth position in our list of people with highest IQ recorded is a British mathematician, Sir Andrew Wiles who is a professor at the Oxford University. One of his recent achievements is proving the Fermat’s Last Theorem which is considered to be the toughest problems in mathematics and something that other people had failed in for more than 350 years. He was awarded the Abel Prize in 2016 for this accomplishment. He has also received numerous other prizes and awards for his works in mathematical research. Wiles has been cited as one of the pioneers of the field and renowned for his contributions to the theory of numbers all through his career starting in the 1980s.

This living legend with an extraordinary IQ level of 170 started working as a professor a the Princeton University in 1981. He was a Guggenheim Fellow at two international institutes in 1985 and 86. Wiles was a Royal Society Research Professor at the Oxford University for four years after which he returned to Princeton. He rejoined the Oxford University again in 2011.

8. Judit Polgar (IQ: 170)

He made major contributions to the field of observational astronomy including the discovery of four satellites of Jupiter, telescopic confirmation of the phases of Venus and observation and analysis of sunspots. Galileo also worked in applied sciences and invented the military compass and many other instruments.

Galileo’s excellence in Copernicanism and heliocentrism were not quite recognized during his time. He had to face opposition from other astronomers and was forced to recant. His life after this was spent under house arrest where he wrote ‘Two New Sciences’ summarizing his work on kinematics and material strength as we know today.

6. Garry Kasparov (IQ: 190)

Garry Kasparov - Highest IQ

Another chess player on our list is Garry Kasparov who is regarded as the greatest chess player in the history of the game, with number one ranking for more than 200 months.
