who developed the first intelligence test and for what reason
Alfred Binet Alfred Binet (French: [binɛ]; July 8, 1857 – October 18, 1911) was a French psychologist who invented the first practical IQ test, the Binet–Simon test.[2] 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.
Pregnancy test Organon International obtained the first patent on a home pregnancy test in 1969, two years after product designer Margaret Crane noticed that the laboratory testing procedure was relatively simple and made a prototype. The product became available in Canada in 1971, and the United States in 1977, after delays caused by concerns over sexual morality and the ability of women to perform test and cope with the results without a doctor.[20]
