Kim Ung Yonga

The world’s most intelligent person is not the world’s richest person such as Mexican telecom mogul Carlos Slim Helú with a net worth of $73 billion, Microsoft founder Bill Gates with a $67 billion fortune, Spain's Amancio Ortega with a net worth of $57 billion, Berkshire Hathaway boss Warren Buffett with a net worth of $54 billion, or Oracle's founder, Larry Ellison, with a net worth of $41 billion. The world’s most intelligent person has been speculated to be Kim Ung Yonga of Korea.

At the age of only four years, Kim Ung Yonga could solve integral calculus problems. Kim Ung Yonga mental scale had an IQ of 210 which he scored at Stanford-Binet test. At 3, Kim Ung Yonga could speak Japanese, Korean, German, and English languages fluently.

Normal Social Skills


Kim Ung Yonga was born on March 8, 1962 to parents who were both professors. Kim attended Colorado StateUniversity where he obtained a Ph.D. in Physics at age 16. Upon return to South Korea, Kim decided to switch from physics to civil engineering where he also obtained a Ph.D in civil engineering.


As a child Kim portrayed normal social skills just like any other average child.

Marilyn vos Savant

And just like any other title, every country would want to have the world’s most intelligent person. Among many others who can be given the title of the world’s most intelligent person is Marilyn vos Savant. Marilyn vos Savant was born August 11, 1946 in USA and is of German and Italian ancestry. Her IQ is very controversial and has varied between 167, 180, 195, 215, and 230.

Marilyn has been writing the column “Ask Marilyn” where she specializes in solving puzzles of logic and mathematics together with answering questions about philosophy, physics, politics, education, and human nature.

Another contender for the title is Christopher Michael Langan. Langan was born in 1952 and is reported to be one of the smartest persons in America.  Lagman IQ has been been measured at between 195 and 210. Langan has his own theory of the relationship between mind and reality and which he calls the "Cognitive-Theoretic Model of the Universe”

it is very easy

Christopher V. on February 12, 2014:

My own experience with I.Q. results and idea of intelligence/giftedness leads me to believe that the tests are as much a hindrance as a benefit (if not more so). I am a highly aware, philosophically astute and critically capable person whose is talented in a multitude of areas with an average I.Q. (110). I am constantly surprised by the level of critical ignorance and limited rational abilities of others (including every single college professor I have ever worked with) and yet I am socially dysfunctional and as far from my own personal definition of success (the only definition that actually has value; though such value is still subjective) as possible.

I could be an anomaly, though I believe that it is more likely that these tests are structured in such a manner as to allow a multitude of variables to adversely affect a score (e.g. mental illness, insecurity, anxiety, waking up on ‘the wrong side of the bed’ the day of the test, etc.) and that they do not effectively cover the full spectrum of what could be reasonably defined as ‘intelligence’ (e.g. a person who has impressive mathematical/logic-oriented skills, a sharp memory and a quick wit can be rationally inept, have a shallow level of awareness and/or have poor critical thinking skills yet still score high on an I.Q. test).

And I am pretty sure that it is impossible to test dead men.

PS: I am sorry if I seem pretentious and reactionary; as someone struggling to find a place in this society I find this subject matter unsettling to say the least.

Cheers and Godspeed.

Mike Fuller on December 07, 2013:

According to the Cox Index ( the most extensive research into the I.Q. of past genius ) The Poet and Politician Byron ( 1788 - 1824 ) has had an I.Q. attributed to him of about 180 on the Stanford-Binet scale!!! Due to the Flynn effect this translates today in 2013 at about 158 on the scale!!! which is about 1 / 7000. On this scale 145 is genius level. Byron was one of the most intelligent of all poets. as intelligent as the top Mathematicians, Physicists and Philosophers of his day. He was also a Libertine, heavy drinker, drug taker and was believed to have been Bi-Polar. Suprisingly ST Coleridge ( 1772 - 1834 ) English Poet, Critic and Philosopher who had a Universal Knowledge Unequalled by any Thinker of his day and was also believed to have been Bi-Polar scored 175 on the Cox List!!! Yet he was the Leading Intellect of the English Romantic Movement!!! Most Nobel Prize Winning Theoretical Physicists score 160 or above on the Stanford-Binet scale!!!

Mike Fuller on September 22, 2013:

I tested my I.Q. to be 144 on '' on the Stanford-Binet Scale.

I could have done better as I was shattered when I took the test and

in addition to that took too much time, when I could have done the test

faster. So I could have easily scored in the 'Genius' range. However my

I.Q. if I scored about 149 on the Stanford-Binet Scale would only be

about 1 / 1000, so there are 7 million people in the world, today in

2013, with higher or much higher I.Q. And in the history of the world

something like ( I think ) about 45 million. So where are so many of

these people on the list!!! Of course the list would be far, far too long.

On other test I've scored 'Above Average', 'Average' and 'Below

Average' so I can't boast too much!!! But it's all interesting to a point

But to quote John Lennon ( 1940 - 1980 ) 'Nothing to get hung

Mike Fuller on September 20, 2013:

Has anyone mentioned Kim Peek 'The Real Rainman' he has

memorized over 12,000 books. Sadly he's dead

but I'd imagine his I.Q. would not be phenomenal. I think WS Gilbert

( 1836 - 1911 ) was exceptionally clever, although unsuccesful as a

Barrister. 'The General's Song' from The Pirates of Penzance'

( 1880 ), 'The High Aesthetic Line' from 'Patience' ( 1881 ) and

'The Nightmare Song' from 'Iolanthe' show a remarkable skill in

construction, without seeming contrived!!! Was John Stuart Mill

( 1806 - 1873 ) on the list, who like Kim Peek could use both sides

of his brain independently, was reading Ancient Greek at 3 and aged

8 was reading Plato ( 429bc - 347bc ). Research into Past Genius

at Stanford University has produced an I.Q. figure of above the

ceiling of 200 on the Terman Scale, as with Swedenborg and

the German Poet and Polymath Goethe ( 1749 - 1832 ). The most

exstensive research into the I.Q. of past genius on the Cox Index puts

Goethe top at 210!!! and Liebniz ( 1646 - 1716 ) second at 205!!!

I have never seen or heard of an I.Q. rating for Hildergard von

Bingen ( 1098 - 1179 ). She may not be up there with the

Leonardos and Goethes of this world, but it would be intresting to

produce a figure for this Writer, Composer, Philosopher and

Polymath to see as such a remarkable woman how she stands against

the likes of Hypatia.

Cheers - Mike ( Fuller )

Mike Fuller on September 20, 2013:

I think the Historian Dr. Lucy Worsley ( b.1973 ) should be top,

she is clever, but above all I think I fancy her!!!

Iury on June 10, 2013:

oh, sorry, now i saw sir isaac newton (just 190 for the founder of modern science, biggest scientist and biggest theologian of all times?)

where is newton? Montaigne talks about how intelligencee is overrated...

Is it fair to calculate IQ on mathematical and linguistic skills, and on General knowledge?

Jason Matthews from North Carolina on February 23, 2013:

I learned a lot from this hub. Thanks for sharing!

Slaven Cvijetic from Switzerland, Zurich on February 19, 2013:

You could have included Goethe too in more smart people. Okay, you may not know him, because he was a German who lived in the 18/19th century, but check him out. His IQ is said to be somewhere from 180-230.

Are people so interested in studying. I guess i'm not. But always stood first in class and university.

Chistina Jhonson-Voors on November 09, 2012:

One of the most intelligent persons I personally I know is the Marques de Ferreira Duke the Cadaval.

Born in Florence Italy 10/11/1942,I worked for him as a private secretary for many years besides his companion and friend.

A man that spoke 9 languages,built entire companies from the ground up,

designed and invented several wind mills,recycled glass,metal and created Green Earth Recycling and Solar Energy in several countries in South America.

Married 5 times and no children he has the hard task to leave an immense fortune to someone able to follow his steps.

A super intelligent man with an I.Q. of 189 and several P.H.D's,Sciences Fellow with 4 doctorates titles and several more in Physics,Marine Biology and Human Non Verbal Communications as well as Space,Stellar travel and the formula to debunk neutrinos and the String Theory as begging to the Universe.

He studied the plausibility of space travel via Worm Holes and Space Continuum.

A mind to reckon with par the the very best scientists anywhere and a member of the U.N. fighting for the rights of children.

He has opened several free orphanages,hospitals,schools,and possesses an incredible amount of the finest real state worldwide.

It is good topic, I like to read such stuffs, however I am surprised that the late prime insister of Ethiopia, MELES ZENAWI is not there. You know guys many people do not know him, maybe he was from Africa/Ethiopia. He was incredibly intelligent, in my humble opinion, he must definitely be one of the greatest/most intelligent people of all time.

i thought Sho Yano is the most intelligent people in the world....he finished college when he is 9 years old.

Patricia Scott from North Central Florida on August 23, 2012:

Some very interesting data you have collected. Are you one of these (no need to answer)? When I was still teaching I had some really bright children whose IQ is measured may or may not reflect that. I had one child whose IQ was 186; he was a sixth grade student. He was an interesting child because he was interested in everything. I had a young girl who had the same numbers and she was not interested in anything. I would be interested in knowing what became of them (I knew them in the 70s).

Ask Marilyn Marilyn has always been a favorite of mine. I am so glad she is on the list not that I am surprised.

Thanks for sharing it with us.

peter rose on August 20, 2012:

i believe you can only really measure a persons true intelegence when you measure both emotional and interlectual of a person , as it is only the whole of any thing, any person that is a true measure .

Mahaveer Sanglikar from Pune, India on August 04, 2012:

Interesting Hub, thank you for sharing.

Grace Marguerite Williams from the Greatest City In The World-New York City, New York on July 13, 2012:

This is an excellent hub. I already knew about James Woods and Marilyn vos Savant. However, I did not know about Kim Ung Yonga. Fascinating piece!

Gothicio on July 09, 2012:

Leonardo da Vinci would be my assumption. A universal genius in every respect. There was nothing that he could not accomplish if he put his mind to it.

Gottfried Wilhelm von Leibniz invented Differential Calculus completely indepdent of Isaac Newton. Leibniz also made rudimentary discoveres on the modern day binary system used by computers, centuries ahead of his time!

Most certainly these two rank up there for me.

josh clint c.gerra on June 26, 2012:

your so most intelegent man in the world

Yashvi on June 11, 2012:

it's really fascinating and inspiring seeing such great people exist... and giving the world their remarkable presence..:))

IQ test is the most suitable measurement for choose the intelligent person according to researches. so according to this site, Engineers are the most intelligent than others.

anirudh mackar on May 24, 2012:

wondering the name of thomas alva edison is not there

anirudh mackar on May 24, 2012:

i guess the most intelligent person is thomas alva edison who does not appear in the above list but had given us the most significant inventions

Robert on May 01, 2012:

IQ's between family members can vary as greatly as any other trait. I have 3 siblings one barely in the above average the other two in the well above average group. And myself according to IQ tests a genius. 150-200 on the Stanford(taken 3 separate times at 8, 16, 24). There are also families with identical twins one of which is solidly average and the other is exceptional. you are born with a certain amount of intelligence potential but environment also plays a factor, as well as ones perceptions of events.

dagny roth from Neverland on April 19, 2012:

Why does intelligence have to involve math? I could be really smart....(shrug) nice hub and voted up! Very interesting.

@Atul Raj,

Everyone else is seeing Charles Darwin had an IQ of 150, not 15. Check your PC display.

SADRO on April 18, 2012:

you know sometime test is not accurate measurement of personal ability

we can respect the ability of some body by seeing what is invited by him, even if an idea.

Atul Raj on April 18, 2012:

Interesting, I enjoyed reading this.

By the way, I think you have a typo for #18. I'm pretty sure you meant that Charles Darwin had an IQ of 150, not 15. Just thought you'd want to know.

lestert on April 04, 2012:

it's really awesome

Alexis on March 21, 2012:

So an IQ of 140- an estimated IQ, no less- is sufficient to make it onto the list?

A list of intelligent people should include the highly intelligent people. An IQ of 140 is in the 99.8th percentile, which is very high, but that is pathetically low compared to the others on the list. Surely there are more intelligent people who could be on that list?

King Lee on March 18, 2012:

For more information it doesn't matter what a bright u have but inside u have no spirit of God that's become a nonsense things to u. I believe that this kind of person will be the most influence by evil.Because most of the bright people they don't believe God. They forget that every thing of what we have now or before are came from GOD.All the thing that we should is always be thankful that we have a vital knowledge to gain and to think of what are the things surrounds us.Talking about intelligence we are all belong with this kind of matter.

Would be interesting to know how it was possible to know the IQ scores of people who died prior to when testing began, in the early 20th century.

Stobals on January 18, 2012:

Most people have never taken a "real" IQ test that is administered by a licensed psycologist.

Internet IQ tests are only scams. Besides true geniuses would never try to measure their intelligence with an IQ test.

if he's so brilliant & his worth in billions,then why not do something useful with it like creating world peace?surely his genes can help him do something for humanity.Seem to me these geniuses are just regular people & if bill gates is so smart what will his IQ do for him in iraq on the battleground? Its all baloney!

I agree a lot with what lela said. Micheal Jackson and his brothers were proof of that. There lives were so strict and ordered that they became superstars at a time whenit was very difficult for blacks to become famous. eVEN AT MY AGE OF 39 MY i.Q HAS INCREASED ABOUT TWENTY POINTS FROM AGE 17 BY THE AMOUNT OF READING,STUDYING PLANNING AND HELL FINANCIALLY THAT i WENT THROUGH. iT MADE ME STRONGER MORE ALERT AND SMARTER EVEN IN MATH WHICH PREVIOUSL WAS MY WORST SUBJECT..

Yusuf on October 31, 2011:

it doesn't matter what your I.Q but what contribution have you made on the world advancemen. Kim youga and marilyn with the highest IQ have not write a hypothesis let alone get a Nobel prize award. But Estein, Newton, with low IQ have their name written on a Gold, even Niel bour, paulins that their name is not found on the list are ever living scholar. I wish i have negative IQ but have my Name existing like that of Newton and won the Nobel prize in physics.

laura on October 16, 2011:

mark zuckerberg should be in the list

Ben from UK on October 12, 2011:

Very interesting and provocative article. The issue of IQ has always aroused interest and will always be so. It's important to point out that intelligence is a potential. We've all been endowed divinely speaking. For me whether you have a high or low IQ it's important that you strive to reach your potential and help others on the way. Moreover, you should know your creator who have blessed you with wisdom. With your IQ get wisdom from above.

An interesting article in every way!

Dave, Langan *has* applied his mind to actual problems. His Cognitive-Theoretic Model of the Universe (CTMU) constitutes the logical framework for a Theory of Everything.

Masanja Masanja on October 11, 2011:

there are many genius people with high IQ than mentioned above in Tanzania but we have no one to see them...pls welcome to find out

Dave on October 10, 2011:

Sorry, I don't consider vos Savant or Langan for example to be the smartest. How is spending a life writing articles for the Sunday paper, or farming, demonstrate superior intelligence? I actually have more respect for the IQ test than many as far as predicting/defining raw intelligence. But imo "smartness" can also only be demonstrated by "results". Someone like Newton or Heisenberg or Turing had plenty of results.

Someone like vos Savant, Langan--they haven't applied their supposed genius to actual problems, haven't made any contributions to science, haven't had any of their theories peer-reviewed, because they haven't made any.

If "intelligence" includes even one iota of "effort" or "ability to use it to find new things out", then people like vos Savant and Langan fail the test.

Obviously some, perhaps like Langan, certainly like Sidis and the later Turing, find their social conditions or personal attacks too detrimental and withdraw from society. This is a decent "defense" of their not contributing as much as they possibly could to science/invention.

But someone like vos Savant and Langan? What is their excuse? Obviously, they need absolutely no excuse if they don't care about advancements. If Langan is happier on a farm or vos Savant writing columns, there is no great fault with that. But solely in the cold context of demonstrating great genius, they've fallen short.
