Lewis Madison Terman (1877-1956) was an American psychologist, noted as a pioneer in educational psychology in the early 20th century at the Stanford University School of Education. Sex differences in personality and temperament are matters of universal human interest. Among all classes of people, from the most ignorant to the most cultivated, they provide an inexhaustible theme for light conversation and humorous comment. They have always been and perhaps always will be one of the chief concerns of novelists, dramatists, and poets. They are rapidly coming to be recognized as one of the central problems in anthropology, sociology, and psychology.
