In the history of human thermodynamics, curiously, two human thermodynamic pioneers, namely German polymath Johann Goethe and American mathematician William Sidis, are both coincidently listed among the few people to have estimated intelligence quotients (IQs) above 200, as shown in the following table, the list of people throughout history with 200+ IQs: [1]


150+ IQ thermodynamicists
Among other notable high-IQ pre-thermodynamicists, thermodynamicists, and human thermodynamics, in Cox’s listing, include: Isaac Newton (IQ=190), main conceiver of the affinity theory, 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”, William Hamilton (IQ=170), author of the 1934 pre-Clausius paper “On a General Method in Dynamics”, as well as Sigmund Freud (IQ=156), founder of psychodynamics, and Stephen Hawking (IQ=160), outliner of concepts on neurological entropy, according to other references.

The Stanford-Binet L-M version measures a mental age that can then be adjusted for a child's chronological age to obtain a true IQ; thus, according to the ratio-IQ math it put his IQ registered at 325 (source: Saturday Evening Post Society, 1996).

Notes:
(a) those estimates shown with an asterisk (*) were determined via the historical comparative IQ method, where IQs were determined based on the case histories of 1,500 biographies of 301 eminent men and women, between 17 and 26 years of age, born 1450 to 1850, as determined in 1926 (thus allowing for a 75-year buffer window of deemed importance, affluence, and difficulty of accomplishment to emerge).
(b) child-hood IQ estimates are indicated with two asterisks (**) meaning that they were determined via the less-accurate ratio IQ method, where a subject's mental age as assessed by the test is divided by their chronological age, the result of which is multiplied by the quotient by 100. Vos Savant, for instance, says her first test was in September 1956, and measured her ceiling mental age at 22 years and 10 months (22-10+), yielding an IQ of 228, meaning that at ten years of age she was as intelligent as an average 22-year old.
(c) Ratio IQs, to note, can vary depending on the reference. Author Miraca U. M. Gross, in her 1998 book Exceptionally Gifted Children, for instance, references Langenbeck (1915) who described a young girl who at age 5 had a mental age of 11 years (and thus a ratio IQ of over 200), and an oral vocabulary of almost 7,000 words.
(d) To have conceived of a type of human thermodynamic theory, one must have been to near adulthood age by about the year 1797 (the term energy, likewise, was coined in 1807 by English physicist and physician Thomas Young), the year in which the caloric theory was beginning to be questioned through the work of Benjamin Thomson (Count Rumford).
