Lewis Madison Terman

Terman, Lewis Madison (1877–1956), U.S. psychologist. The popular term IQ (intelligence quotient) is a result of his development of an English-language version of the French Binet-Simon intelligence tests (1916, revised in 1937 and 1960). Terman's studies concluded that gifted children with high intelligence experienced healthy and stable development from childhood to adulthood. The findings were discussed in his book Genetic Studies of Genius (1925–59). He was a professor at Stanford University (1921–42).
