About the author

Born in Indiana in 1877, he became an American psychologist and a major figure in educational psychology. He taught at Stanford and is most closely associated with the Stanford-Binet intelligence test, an American revision of earlier work by Alfred Binet and Théodore Simon.

He also launched a famous long-term study of gifted children, following participants over many years to examine how high ability developed across a lifetime. That work made him widely known in psychology and education, and his influence continued long after his death in 1956.

His legacy is important but also contested. Alongside his contributions to intelligence testing, modern accounts note his support for eugenic ideas, which has led later readers to reassess both his work and its impact.
