Cox IQ (summary a) f
Cox IQ (summary b)
A 1994 summary of Cox’s IQs by Dean Simonton. [2]
In IQs, a Cox IQ is one of the 301 IQs assigned by American psychologist Catherine Cox of the three-hundred greatest geniuses that lived between 1450 and 1850, as published in her famous 1926 book Early Mental Traits of Three Hundred Geniuses. [1]

This was the first attempt at assigning geniuses IQs, generally based on the methodology Cox's PhD advisor Lewis Terman, inventor of the modern IQ scale, used in assigning Francis Galton with an IQ of 200.

Cattell 1000
See main: Cattell 1000
In 1894, American psychologist, Science editor, and Popular Science Monthly founding editor James Cattell, starting with several standard reference works, compiled a list of the 1,000 most eminent creators and leaders in Western civilization, ranked according to amount of space they received, the results of which he summarized in his lecture “A Statistical Study of Eminent Men”. [3]

Started with Cattell’s list, Cox selected the best of the best, in terms of criterion such as those who achieved eminence own their own (as contrasted with throne inheritance based eminence), highest eminence rankings, etc., and also those who were of adulthood age from 1450 to 1850. [2]

Ranking methodology
To make this list, a team led by Cox, Lewis Terman, the co-inventor of the IQ test, and psychologists Florence Goodenaugh and Kate Gordon gave an historically determined IQ ranked listing of the top 300 geniuses who lived between 1450 and 1850, by reading through 1,500 biographies and to each genius independently assign an estimated intelligence quotient, based on The Stanford Revision of the Binet-Simon Intelligence Scale, based on each individual’s life accomplishments and childhood abilities.
