Alfred Binet

Alfred Binet, born Alfredo Binetti, was a French psychologist who together with Théodore Simon invented the first practical intelligence test, the Binet–Simon test. In 1904, Binet took part in a commission set up by the French Ministry of Education to decide whether school children with learning difficulties should be sent to a special boarding school attached to a lunatic asylum, as advocated by the French psychiatrist and politician Désiré-Magloire Bourneville, or whether they should be educated in classes attached to regular schools as advocated by the Société libre pour l'étude psychologique de l'enfant (SLEPE) of which Binet was a member. There was also debate over who should decide whether a child was capable enough for regular education. Bourneville argued that a psychiatrist should do this based on a medical examination. Binet and Simon wanted this to be based on objective evidence. This was the beginning of the IQ test. A preliminary version was published in 1905. The full version was published in 1908, and slightly revised in 1911, just before Binet's death.
