French psychologists

Alfred Binet (French: [binɛ]; 8 July 1857 – 18 October 1911), born Alfredo Binetti, was a French psychologist who invented the first practical IQ test, the Binet–Simon test. In 1904, the French Ministry of Education asked psychologist Alfred Binet to devise a method that would determine which students did not learn effectively from regular classroom instruction so they could be given remedial work. Along with his collaborator Théodore Simon, Binet published revisions of his test in 1908 and 1911, the last of which appeared just before his death.

Georges Dumas (6 March 1866 – 12 February 1946, Lédignan) was a French medical doctor and psychologist.Dumas was a student of Théodule-Armand Ribot. His main work is The Treatise of Psychology (1923–1924, Le Traité de Psychologie). He wrote many articles for the work and oversaw its publication in two volumes. Many of the leading French psychologists of the time contributed to the work. A new completed edition (The New Treatise of Psychology, Le Nouveau traité de psychologie) was published between 1930 and 1949 in 10 volumes.
