Granville Stanley Hall was graduated from Williams College in Williamstown, Massachusetts, and received a Ph.D. from Harvard University in 1878. He studied theology and philosophy in Germany and reported the Franco-Prussian War for American newspapers from 1868 to 1871. After teaching at Antioch College in Ohio and at Harvard, he returned to Germany to study physics, physiology, and experimental psychology. In 1882 he was granted S1,000 to establish a psychological laboratory at Johns Hopkins University, where he pursued his research in experimental psychology and trained men who would become eminent scholars, including James Cattell and John Dewey. Hall's research into the psychology of learning contributed significantly to the growing debate over the differences between schooling and education. His research, which focused carefully on childhood and adolescent psychology and the accumulation of life data, helped put the study of education on a firm scientific basis.
