G. Stanley Hall

Granville Stanley Hall (1844 to 1924) was an American psychologist and educator who earned the first doctorate in psychology awarded in the United States, at Harvard University in 1878, where he had met William James. Inspired by Wilhelm Wundt, he studied in Berlin and briefly in Wundt's Leipzig laboratory, then taught at Johns Hopkins University, where in 1883 he began the first formal American psychology laboratory. He founded the American Journal of Psychology in 1887, became the first president of the American Psychological Association in 1892 and was the first president of Clark University from 1889 to 1920. His interests centred on human life span development and evolutionary theory, and he helped shape educational psychology through his study of how adolescence affects education. He invited Sigmund Freud and Carl Jung to lecture at Clark University in 1909.
