Real-time imaging: showing electrochemical activity in the brain, the seat of intelligence.

In intellect categorizations, IQ: 200+ refers to the individuals, listed below, throughout history, who have had documented, tested, estimated, or childhood-ratioed intelligence quotients (IQs) at or above 200 (11 in the 225+ range, 5 in the 206-224 range, 3 in the 201-205 range, and 8 at the 200 range). Many of these high-end ceiling range IQ estimates, however, are purely superfluous miscalculations, as discussed below (see also: IQ: 225+)

“IQ is thought to be a measure which expresses the relative brightness or intelligence of any given individual.”

– Catherine Cox, Early Mental Traits of 300 Geniuses (1926)

Those pictured in the third column were involved in the development of human thermodynamics (HT), thermodynamics (T), or its precursors; Sidis, Hirata, and Goethe having published views (HT pioneers) on the subject, Galton being a commentator, and Leibniz being one of the developers of calculus with his introduction of the notation of the modern differentiation d and integration ∫ symbols used in thermodynamics, and noted for his vis viva (pre-kinetic energy) theories; Newton being the originator of affinity chemistry; and Einstein raised in thermodynamics. The last column shows the modern function, depicted according to the laws of universe (laws of thermodynamics), indicative of each person's theory of existence (TOE), as described in each individual's self-defined greatest work: [1] Bolded IQs are Cox 1926 estimates, underlined IQs are Buzan 1994 estimates, italics IQs are Stanford-Binet ratio estimates, red IQs are 1989 Hoeflin Mega test estimates; asterisked IQs* have detailed discussion on the references page; other standard-font IQs are cited on a case-by-case basis.


Last man to know everything
To situate the premise of the 200+ IQ in the context near mastery of knowledge, we will highlight those individuals who have been famously called “the last man to know everything”, one, from the above table, being Goethe (IQ=180-225), some even having books written on them with this title affixed. At least six people have been said to have be in possession of this trait of total knowledge attainment, who are listed below chronologically: [43]

#	Last All-Knowing Person		IQ	Quick Description
1.		Athanasius Kircher (1602-1680)		German scholar; described as the "master of a 100 arts".
2.		Thomas Young (1733-1829)		English physician and scientist; translator of the Rosetta stone, inventor of the double slits experiment (1801), can first to coin the term energy (1807), in its modern formulation.
3.		Johann Goethe (1749-1823)	180-225	German writer and scientist; described as the "prince of the mind"; founder of human chemistry.
4.		Alexander Humboldt (1769-1859)	185	German naturalist; the founder of biogeography.
5.		Joseph Leidy (1823-1891)		American paleontologist and anatomist; noted as a vigorous promoter of Darwinian evolution.
6.		Thorstein Veblen (1857-1929)		Norwegian-born American economist; initiator of the institutional economics movement; worked to bring the evolution views of Darwin and Spencer to bearing on human societies.

Three of these individuals specifically having had books written about them with this title:

Thomas Young (1733-1829)	Joseph Leidy (1823-1891)	Athanasius Kircher (1602-1680)

Of note, sometime between 1700 to 1900, people began to profess the view that the body of "known knowledge" had become so large that it was no longer possible for one person to know everything. This is certainly debatable, but, nevertheless, this idiom is frequently regurgitated, as a sort of self-substantiating crutch to what tends to be modern self-appeasement. Interesting in this group of all-knowers, is their connection to each other. To exemplify, the following 2006 quote by English science historian Andrew Robinson shows the grouping of three of these all-knowers: [46]

“Young deserves to be called a Renaissance man or uomo universale, like Goethe, Franklin, or Humboldt—or even, maybe, the most eminent example of such a man in his age.”

— Andrew Robinson

English science historian, The Last Man Who Knew Everything: Thomas Young (2006)

The close association of these intellectual know-it-alls is striking: Kircher was frequently cited by Goethe: for instance, in his search of a science of optics to counter Newton’s, Goethe rediscovered the earlier work of Kircher, and to the extent that Kircher’s theories kept popping up in Geothe’s path, is exemplified by Goethe’s circa 1800 comment: “thus, entirely unexpected, Father Kircher is here again.” Kircher’s work on hieroglyphics translations was frequently discussed and critiqued by Young. Young endorsed Goethe’s explanation of certain pathological conditions of color-blindness and color confusion; had no objection to Goethe’s description of Physische (Physics) and Chemische Farben (Chemical Colors), but expressed great aversion to Goethe’s Farbenlehre (Color Theory) and went to great lengths to disprove it.

Goethe’s connections with Alexander Humboldt date back to 1797, when he and Alexander and Wilhelm Humboldt formed a close circle in Jena to pursue scientific research in anatomy, chemistry, mineralogy, physics, and zoology. Goethe’s opinion of Humboldt was exceedingly high, referring to him as a ‘cornucopia of sciences’ and stating that “a person cannot derive as much information from books in a week, as Humboldt can convey in an hour” and “I have never known anybody who has so harmoniously combined such determined activity with so much intellectual universality.”

Leidy, in his late 1870s search to prove that flies were the agents of contagion, acknowledged Goethe as being the first to observe fungi in flies; he was also knowledgeable of Goethe’s pre-Darwin theories of change from one form to another, of many forms arising from a few.

Goethe: the ceiling genius.

Goethe: polymath, universal genius, the last 'true' man to know everything
Central among this group of all-knowing sages, as discussed further below, is German polymath Johann Goethe, whose ranking is unprecedented: largest active vocabulary (90,000 words); #1 Cox genius (out of 300); #2 Buzan genius (out of 100); #2 biggest world author (WorldCat literature: 2010); at age 7, to sugar the pill of grammar, he invented a novel in which the members of a family in various parts of the world wrote letters to each other in six different languages and styles; at age 16, entered the University of Leipzig; at age of 19 (1768), during his studies of Fraulen von Klettenberg and Paracelsus, was conducting chemical experiments to reveal the ‘principle that permeates the whole universe’; at 20 he had published his first volume of poems and had studied enough medicine to qualify to as a physician; by age 21, he had prepared a PhD dissertation on history; by 22, prepared and defended 65 theses, received his law degree, and began practicing; by 24, he had written his great tale Werther and by 26 was world famous; at age 31 (1780), had worked out the basics of a biological 'metamorphosis' theory of evolution, later to be cited by Darwin as being a forerunner to his own theory; at age 36 (1785), demonstrated through comparative osteology that humans posses an intermaxillary bone of the upper jaw as found in other animals (as proof of evolution); and of greatest significance, in 1809, at the age of 60, became the founder of the modern 21st century science of human chemistry, the study of chemical reactions between people; at age 77, was working out a law to explain the blue color of the sky (a phenomenon not fully explained until 1871 by John Strutt); and in 1832, at the age of 82, the year of his death, finished the work he is best known-for Faust, the story of a man who is striving to learn everything that can be known and who sells his soul to the devil so to obtain the ultimate in ‘infinite knowledge’. Goethe's mastery of knowledge is summarized by the following collection of quotes, from the perspective of other famous polymaths, geniuses, genius studies experts, famous people, and Nobel Laureates, the last of which situates Goethe as the intellectual forefather to Einstein (who kept a bust of Goethe and a fifty-two volume set of Goethe's collected works in his study): [45]

“Goethe, he used to say, was the last man in the world who knew everything; after Goethe (d. 1832), there was too much to know for any one person to know it all.”

— Anon German school teacher (circa, before 1966)

“Goethe was last true polymath to walk the earth."

— George Eliot (IQ=185)

English novelist (1871)

“Goethe comes as close to deserving the title of a universal genius as any man who has ever lived.”

— Sterling Brown

African-American literature professor (1973)

“One rater (M) has scored on the basis of the record of Goethe’s youth an IQ of 225. Goethe’s true IQ may in the history of mankind have been equaled in a few instances; one may well wonder whether it has ever been exceeded?”

— Catherine Cox

American psychologist, Early Mental Traits of 300 Geniuses (1926)

“Without intellectual and individual freedom there would have been no Shakespeare, no Goethe, no Faraday.”

— Albert Einstein (IQ=160-225)

German-born American physicist (1933), kept a plaster bust of Goethe in is drawing room.

“History is unkind to polymaths. No biographer will readily tackle a subject whose range of skills far exceeds his own, while the rest of us, with or without biographies to read, have no mental ‘slot’ in which to keep a polymath’s memory fresh. So the polymath gets forgotten or at best, squashed into a category we can recognize, in the way Goethe is remembered as a poet, despite his claim to have been a scientist.”

— Alexander Murray

Oxford historian, 1994 bicentenary symposium for English polymath William Jones

“Scholars agree that Goethe was the last universal genius: practically nothing within reach of the human mind escaped his attention.”

— Walter Wadepuhl

German-born American German studies professor, Goethe’s Interest in the New World (1932)

“It was upon hearing Goethe’s beautiful essay on nature that I decided to go to medical school.”

— Sigmund Freud (IQ=156)

Austrian psychologist, autobiograhical notes (1873)

“The middle of the eighteenth century witnessed the first powerful revolt against cultural tradition, which is marked by Rousseau. This tradition was restarted by universal genius Goethe. But it was restarted for the last time. Goethe had not been succeeded by another universal genius.”

– Ernst Curtius

German literary scholar, “The Medieval Bases of Western Thought” (1949)

“For what concerns chemistry, Goethe was not far from Newton.”

— Ilya Prigogine

Belgian chemical thermodynamicist (1984), Nobel Prize thermodynamics (1971)

“Since my method is juxtaposition, I delight in bringing together universal genius Goethe, with Sigmund Freud, Samuel Johnson, and Thomas Mann.”

— Harold Bloom

American literary critique, Genius: A Mosaic of One-Hundred Exemplary Creative Minds (2002)

“In 1808, German polymath Johann Goethe used Bergman’s affinity tables as a basis for human behavior and in doing so wrote the classic novella Elective Affinities, a book that marks the start of the science of human chemistry.”

— Libb Thims

American chemical engineer, Human Chemistry (2007)

“Throughout his life Einstein was a man of the book, to a much higher degree than other scientists. The remarkably diverse collection of volumes in his library grew constantly. If we look only at the German-language books published before 1910 that survived Einstein’s Princeton household, the list includes much of the cannon of the time: Boltzmann, Buchner, Friedrich Hebbel, the works of Heine in two editions, Helmholtz, von Humboldt, the many books of Kant, Gotthold Lessing, Mach, Nietzsche, and Schopenhauer. But what looms largest are the collected works of Johann von Goethe in a thirty-six volume edition and another of twelve volumes, plus two volumes on his Optics, the exchange of letters between Goethe and Schiller, and a separate volume of Faust.”

— Gerald Holton

German-born American physicist (2008), Harvard PhD under Percy Bridgman, 1948

To sum up this collections of quotes, Goethe once famously said that “if one does not know what went on for the last three thousand years, he or she remains ignorant, merely surviving from day-to-day.”

Buzan's 1994 list of the 14 greatest geniuses. [18]

A curious phenomenon among prodigies is the ability to name the day of the week for any given date in history; a tool often used to entertain people at social gatherings and on talk shows. The phenomenon seems to arise naturally in such individuals. Sidis, for instance, by the age of five had devised a formula whereby he could name the day of the week for any given historical date. [30]

Captioned picture of Goethe (age 15) from the 1927 Journal of Heredity article “The Child Hood of Genius”, by scientist Paul Papenoe, with the caption: “Goethe at the age of fifteen. ‘His IQ may in the history of mankind have been equaled in a few instances, one may well wonder whether it has ever been excelled.’ From the facts which are known of Goethe’s childhood he is credited with a youth intelligence quotient of 180, which means that at five years of age he was far advanced as the average child of nearly ten. When he was twelve he amused himself by planning and sketching out a novel written in seven languages.” [3]

150+ IQ thermodynamicists
Among other notable high-IQ pre-thermodynamicists, thermodynamicists, and human thermodynamics, in Cox’s famous 1926 listing, include: Antoine Lavoisier (IQ=170), formulator of the caloric theory, Lazare Carnot (IQ=170), father of Sadi Carnot and founder of the École Polytechnique, the first “school” of thermodynamics”, and William Hamilton (IQ=170), author of the 1934 pre-Clausius paper “On a General Method in Dynamics”, Herman Boerhaave (IQ=165), formulator of Boerhaave's law (precursor to caloric theory), of James Watt (IQ=165), steam engine pioneer, Stephen Hawking (IQ=160), a founder of black hole thermodynamics and outliner of concepts such as neurological entropy, as well as as well as Sigmund Freud (IQ=156), founder of psychodynamics.

Another noted high IQ HT pioneer is American mathematician Norbert Wiener, a former child prodigy who completed his BS in mathematics from Tufts College at age 14 and PhD in mathematics from Harvard at age 18, who while in the class of Harvard mathematics professor Edward Huntington’s (circa 1909-11) commented about his classmate William Sidis: [16]

“Both Sidis and I were in the class, and it was there that I first became aware of the boy's real ability and how great a loss mathematics suffered in his premature breakdown.”

During his first year of classes, Sidis left Harvard for some months because of a nervous breakdown shortly after having given his speech, at age 11, on four dimensional bodies. To note, Wiener's human thermodynamics theories, as found in his 1948 Cybernetics and 1950 The Human Use of Human Beings, are on par or comparible to those of Sidis.

Another noted high IQ child prodigy was Hungarian-born American mathematician John Neumann (IQ=163-180), one of the founders of quantum thermodynamics, who by the age of six was able to divide eight-digit numbers in his head, exchange jokes in classical Greek, and to memorize the names, numbers, and addresses in phone books (displayed as a game to guests), and at the age of 23, simultaneously competed a BS degree in chemical engineering, from the Technische Hochschule Zurich, and a PhD in mathematics, with a thesis on set theory, from Pázmány Péter University in Budapest.

To have conceived of a type of human thermodynamics theory, as Goethe, Sidis, and Hirata did, one must have been to near adulthood age by about the year 1718 the year in French chemist Etienne Geoffroy made the first affinity table, a tabulation of the forces of reaction between chemical species, the measure of this force, after 1882 (via Hermann Helmholtz), being determined through free energy change calcuations.

Burned-out or defunct IQs
Based on the ceiling IQ benchmark , discussed above, if one reads or hears claims of individuals scoring past the Cox-Buzan ceiling (213+) on an IQ test, e.g. De Mello (400), Kearney (325), Sidis (300), Tao (230), Savant (228), Hirata (225), or others (discussed below), we would define these as false positive IQs or burnout IQs, in that they are miscalculated over-estimates. In other words, these overestimates result from age-ratio biasing and which tend to be indicative of productivity burnout prior to age 25, as evidenced by four of six of these individuals: De Mello (age 11 burnout), Kearney (age 17 burnout), Sidis (age 22 burnout), and Savant (never burned). Then we have individuals who as children had estimated 200+ IQs, supposedly in the genius range, but as adults did not seem to realize their supposed genius potential of getting into historical genius ceiling stardom, not necessarily "burning out", but fettered out into the anonymous average or above average crowd, in terms of adulthood occupational achievements. These prodigies, listed below, can be considered to have "deburned" their potential or stepped out of the lime light burn.

1.		Adragon De Mello (1976-)	400 (age 5)	Set a world record by graduating from college at age 11 (BS computational mathematics); after which he returned to junior high school; and now works at Home Depot.
2.		Michael Kearney (1982-)	325 (age 4), 200 (age 14)	Set world record by graduating from college at age 10 (BS anthropology); MS biochemistry (age 14); MS computer science (age 17); now plays poker and enters game shows for a living.
3.		William Sidis (1898-1944)	200, 250-300 (age 42)	Tested out in Harvard Medical school entrance exams (age 9); set record by entering Harvard at age 11; had a "breakdown" at about age 12; graduated BS mathematics (age 16); Harvard Law school age 17; published work on thermodynamics age 22; withdrew from public life at age 24; became vagabond thereafter.
4.		Nathan Leopold (1904-1971)	200, 206-210	Reported to be a child prodigy with an IQ of 210 who spoke his first words at four months; graduated from the University of Chicago at the age of 19 (1923) with honors; entered Chicago Law School that same year and while making plans to transfer to Harvard Law School in the fall, he and another prodigy named Richard Loeb, who was himself the youngest graduate in the history of the University of Michigan, kidnapped and killed Loeb’s second cousin Bobby Franks (age 14), the son of a Chicago millionaire.
5.			268	Speaking grammatically correct sentences at three months of age; at age 3.5, he read, wrote, and spoke several languages, studied mathematics, and composed music, played the violin; at age 7-8 was attending the MIT computer lab doing programming; obtained a perfect score on the Stanford-Binet at age of about 8; the term “omnibus prodigy” was coined to describe him, as his talents were not bounded within a single domain; child scholar expert Halbert Robinson commented that “Adam was perhaps the most gifted child ever tested on the Stanford-Binet”; he is currently a computer programmer and music composer, and is listed as the premier case of the “gifted underachiever”.
6.		Marilyn vos Savant (1946-)	228 (age 10), 186 (age 40)	Perfect Stanford-Binet score (age 10); pregnant at age 16; college dropout shortly thereafter; then began working in the family laundry business; at the age of 37 (1983) was having dinner with a lawyer Andrew Egendorf who wanted to write a book about high IQ societies (Savant was in Mensa), and suggested to Savant that they "cash in" on her 1956 test score by sending it to Guinness Book; which he did the following year, and by 1985 she was listed as the IQ record holder, and owing to this fame landed a job as newspaper columnist at Parade Magazine.
7.		Kim Ung-Yong (1963-)	200-210	Started taking physics in college at age 4; began working with NASA at age 12; PhD in nuclear physics age 14; burned out at age 16, returned to Korea, wishing to remove himself from the public eye; re-entered a mediocre local university obtaining a PhD degree in an easier field of civil engineering; in an interview with the press, on this switch, he has commented “I was not a loser, but just wanted to live ordinarily.”
8.		Michael Grost (1953-)	200 (age 8)	Supposedly had an “IQ so far above 200 it could not be measured meaningfully”; giving college lectures age 8; BS (age 15), MS (age 17), and PhD (age 23) all in mathematics; works as a systems architect at Detroit computer company.
9.		Edith Stern (1952-)	200, 201-203	BS science (age 15), PhD mathematics (age 18), in 2000 was working for IBM in secret computer software research and development.

Sidis, however, is a curiosity in this group, in that his only major work was the 1920 book The Animate and the Inanimate, published at age 22, he is judged by other high IQ peers, such as American mathematician Norbert Wiener, a former child prodigy himself (BS in mathematics from Tufts College at age 14, PhD in mathematics from Harvard at age 18), to have had “real ability” and was still testing out in the 250+ range into his 40s.

A point to note, regarding the terms intellectual "brightness", all-time "star" genius, "burnout" IQs, and "deburners", etc., is that these are not simply figures of speech or pure analogy (as many would argue), but rather terms modeled on the phenomenon of hydrogen burning inside of stars, where gravitation pressure acts to squeeze central "star" hydrogen atoms, causing chain thermonuclear reaction which result to release energy.

By no coincidence, human beings are large hydrogen atoms (made of 26-elements to precise), termed "human molecules", and this same pressure-induced burning phenomenon acts in the human sphere, in which human electromagnetic pressure acts to squeeze central "star" human molecules, e.g. Geothe, Da Vinci, Newton, Einstein, etc., causing human thermonuclear reactions (an high energy type of human chemical reaction) which result to release energy.

These types of high-energy reaction are indicative of the laws, workings, and movement of the universe. Those individuals forced into this universal current, so as to become adult star "human molecules" or all-time "bright" geniuses, are thus different than those who may have had the potential to become stars, but failed to react, for whatever reason.

Other possible/questionable 200+ IQs?

● Adrian Seng (1977-) (IQ=233) spoke first word at 13-months; taught himself to read before age 2; by age 3, could read, write, and do math at a six-year-old level; at age 3.5 could multiply two-digit numbers in his head. Quote: “at age of 6 years he was assessed on the Stanford-Binet and was found to have a mental age of 14, a ratio IQ of more than 220 [possibly: (14/6)*100=233]; scored 760 on the SAT (mathematics) at 8-years 10-months; completed BS at age 15; completed MS at age 17; then won major scholarship to study math at a prestigious American university. [9]
● Gena Leung (1983-) (IQ=210) at age 5-years 7-months, began to teach other children how to read; at age 11, scored 730 SAT-M; at age 10 was studying French, Latin, and Japanese; completed her university entrance math qualifications at age 13; at age 16, was a certified violinist and also a member of the five person Australian team that competed in the International Physics Olympiad; was diagnosed with depression at age 18, placed on medication, and withdrew from school for a year; at age 20, has “completed a three-year bachelor of medical science degree and is now commenced a four-year bachelor of medicine degree. She wants to make her career in medical research”; quote: “assessment on the Stanford-Binet L-M, two weeks after her tenth birthday, revealed a mental age of 21 years and thus a ratio IQ in excess of 200 [specifically: (21/10)*100=210]”; [21]
● Ian Baker (1980-) (IQ=200); spoke first word at 12-months; reading and counting before age two; quote: “[at 9 years and 3 months] Ian scored a mental age of 18 years and 6 months and thus a ratio IQ of 200.”. [9]

Some of the people listed here are found with mentions of high IQ scores simply based on having taking various 40+ question IQ tests (which take about 100-hours to obtain a high score); then, via various convoluted extrapolation formulas, go on to claim that an obtained score of say 44/45 equates to an IQ of 190 and that if this score is ratioed to another so-and-so scale it gives a “ratio IQ” of 250, etc. Scoring 48/48 on what is called the mega test, for instance, is said to give an adult or deviation IQ of 210+. Thus, supposedly, if one takes a 100-hour logic problem test and gets a perfect score, one will be as smart as Goethe, which is an illogical conclusion.

The Mega Society lists a number of seemingly unknown individuals, being qualified by their “Mega Test”, as having ratio IQs of 204 or above: Anthony Bruni, Arthur Kantrowitz, Jim Ferry, John Sununu, Benoit Desjardins, Keith Raniere, Kevin Langdon, Paul Johns, Ferris Alger, Rick Rosner, Greg Treyling, Ronald Hoeflin, Solomon Golomb, Steve Schuessler. These types of scoring methodologies make little sense when compared, for instance, to someone like Einstein (IQ=160) who spent decades on one single question: “what happens when you try to run alongside a beam of light?” or Goethe (IQ=210-225) who spent about half a century on the question of the relationship between chemical affinity, love, life, work, and death.

BS mathematics (1985) at age 13, BS physics (1986) age 14, and PhD (1989) age 17 at the University of Oxford; academic post at Harvard (1990) at age 19, and associate professor with tenure at the University of Michigan in 1997.	● Alia Sabur (1989-) (IQ=?) completed BS (2003) in applied mathematics from Stony Brook University at age 14; MS (2006) and PhD in materials science and engineering at Drexel University; professor of mathematics at age 19.
● Eric Demaine (1981-) (IQ=?) BS age 14; MS mathematics age 15; PhD age 20; joined the MIT faculty in 2001, at age 20, reportedly the youngest professor in the history of MIT.	● Vinodhini Vasudevan (1986-); read 100 books the summer she was 5 (link); mastered college algebra at age 8; at age 12 set record by becoming the youngest person to score a perfect 1,600 (800 on math, 800 on verbal) on the SAT (link), correlates to IQ 165 (link); could be age ratioed higher (e.g. (18/12)*165=247?; in 2007, at age 21, graduated from MIT with a BS in electrical engineering with a minor in biomedical engineering (link).
● Moshe Kai Cavalin (1998-) completed an associate’s degree in astrophysics (age 11) in 2009.	● Balamurali Ambati (1977-) mastered calculus age 4; BS age 13 from New York University; MD at age 17 from Mount Sinai School of Medicine; ophthalmology residency at Havard; in circa 1987, Set a goal to become the youngest graduate of medical school after reading about Ben-Abrahman’s record in the Guinness Book (link), did so at age 17 years, 294 days.
(1997-) (IQ=?) at age 3, could speak and read both English and Korean; started taking college courses at age 10 (link); was taking Calculus II,Intermediate Chinese Conversation, Physics with CalculusI, at age 12 (2009), at Florida International University, plans to double major in physics and math (link).

● Jay Luo (1970-) BS mathematics at Boise State University in 1982 (age 12) with a B+ average, degree completed in three years (link); started graduate work at Stanford afterward, but dropped out. Interestingly, the Tao family (Terence Tao) had met Jay Luo during a trip to the US and noted the pitfalls of the approach of parental fixation with child’s IQ as evidenced by Luo’s burnout (link).

Fake/joke/scam 200+ IQs
One can also find random anonymous parents online postings making claims to their children's intelligence (e.g. “As a parent of a 7 year old with 200 IQ, what advice would you give to our family?” (2002 article); this, generally, is an example of the difference between parentally-driven (derived) IQ scores (e.g. Sidis) versus self-driven (derived) IQ scores (e.g. Einstein).

● Avi Ben-Abraham (1957-) Quote: “His IQ is so high that it cannot even be measured.” Boasting: mastered relativity at age 7; MD at age 18 from the University of Perugia, Italy; held Guinness Book record 1987-90 as youngest doctor; supposedly all faked or scammed (link, link, link, etc.)?

● Naida Camukova (c. 1976-) (IQ=199.37) (Einstein assigned ceiling IQ=200) (link); started talking age 1, learned to read and write at age 2; age 14 was enrolled in both Moscow State University (history) and Daghestan State University (literature); began medical school at age 9 (or 15); speaks seven languages; age 25 became professor of history and literature; has published 25-books and read 3000 books; with photographic memory (able to remember even comma placements in books); only child of a neurosurgeon mother and lawyer father; had brain hemorrhage at age 23 (was in coma for 20-days) (Wikipedia) (Facebook), declared the world’s most intelligent person by the Moscow Institute from Brain Research; supposedly a fake or scam (link)?

● Chris (or Justin) Chapman (1996-) (IQ=298) at age 6 the IQ purported was fabricated by his mother Elizabeth Chapman; who had her child removed after he attempted suicide a year latter. [5]
● William Alfred Quannigton (Child IQ=350+; Adult IQ=300+) is a fictional person introduced as a joke by an anonymous poster on Sep 5, 2006 to an AnswerBag forum: "What is the highest rating of IQ ever recorded?", claiming that he was Quigly Anderson, who was writing book on the 50 highest IQs ever recorded. His top ten list quickly became incorporated into various high IQs Internet lists. It was likely a on William James Sidis. See examples (here, here, here, etc.).
● Iqbal Saleh Abba (IQ = 235) (link) (link) Quote: “the smartest person in the world is Iqbal Saleh Abba whose documentation were sent to the Guinness Book of World Record's office in England; he had dethroned Marilyn vos Savant who had different and inconsistent IQ scores by delivering an exact psychometric test document with clear cut, credible result sworn in an affidavit form by the person who had tested him. The book, however, felt overwhelmed that they had to dethrone vos savant and in this insecurity just took off the IQ category altogether [1990]. It is a shame that they did not mention him in IQ Hall of Fame; people could certainly benefit from this knowledge.” (link) Seems to be a fake or non-existent person; not found in Google books or Google news clippings?

Colloquial IQs
In the common vernacular, when queried as to "who is the smartest person of all time", the average person, by far, tends to first think Einstein, then Da Vinci, followed by (in various orders): Newton, Franklin, Edison, Hawking, Gates, Galileo, Curie, Shakespeare, Freud, among others, such as Beethoven, Hitler, Plato, Aristotle, Jefferson, Tesla. Of note, by far Einstein is the biggest response: people tend to name Einstein, for example, about four times that of Da Vinci. [20]

Films
● The Kid with the 200 I.Q. (1983).
● Real Genius (1985) supposedly based on real students from California Institute of Technology (link).
● Good Will Hunting (1997) supposedly modeled on William Sidis (link):

(a) The part where Hunting defends himself in court is certainly based on the part where Sidis defended himself in court.
(b) Hunting could also, however, be modeled on a young music prodigy named Henry Cowell, whom Lewis Terman met in circa 1920 at Stanford University, who had been unschooled since the age of seven and at the time was working as a janitor in a one-room schoolhouse not far from the Stanford campus. Cowell would sneak away from his job and play the school piano. Terman was fascinated by him and tested his IQ to be at genius level of 140 (source, Gladwell, Outliers).
(c) The parts where Hunting solves two famous unsolved problems he finds on the hallway chalkboard is, supposedly, based on the 1939 story of Berkeley PhD mathematics student George Dantzig coming late for class, finding two famous unsolved problems in statistics on the blackboard, and assuming they were homework problems (link).
(d) The scene where he cites sentences and page numbers of books is similar to the claims of Naida Camukova (above) who claims to read a book a day and have a photographic memory of over 3,000 books, where she remembers every comma in each book.
(e) Other notables mentioned in the movie include: Srinivasa Ramanujan (190-210) (link) and Theodore Kaczynski (IQ=170, age 10).
