Lewis Terman (1877 –1956) was an American psychologist who pioneered the the study of educational psychology while at the Stanford Graduate School of Education. Two of his best known accomplishments were the revision of the Stanford-Binet IQ test and initiating the study called the Genetic Studies of Genius, a longitudinal study (hyperlink?) of gifted children.
Unlike previous studies of genius that focused on adults and looked only at the subject's history, he studied the subjects as they proceeded from childhood into adulthood and followed their careers. Terman also served as president of the American Psychological Association, was a eugenicist, and a member of the Human Betterment Society. His groundbreaking study of gifted children continued after his death and is set to continue until the last participant dies.
