Alfred Binet
He created the first modern intelligence test not to label children, but to identify those who needed extra help in school.
1857–1911 (age 54)·French psychologist, IQ test developer·Birthday: July 8
Biography
Alfred Binet was a French psychologist who approached the human mind with a practical, compassionate eye. Working in the bustling intellectual atmosphere of late-19th century Paris, he studied topics from hypnotism to the psychology of chess players. His defining moment came when the French government asked him to find a way to distinguish between children who were struggling in school due to intellectual disability and those who were simply unmotivated. With Théodore Simon, Binet developed a series of simple, age-graded tasks—the first practical intelligence scale. Crucially, Binet saw his test as a flexible tool for identifying educational need, vehemently opposing the idea that intelligence was a single, fixed, inherited trait. His work, though often later misused, was born from a desire to help.
