- 1911 – Alfred Binet, French psychologist and author (b. 1857).
Martha Gertrude Burk (born 18 October 1941) is an American political psychologist, feminist, and former Chair of the National Council of Women’s Organisations.
Alfred Binet (08 July 1857 to 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.
