Carl Allanmore Murchison (1887–1961) was an American psychologist and an early promoter of the discipline of psychology. Unlike most psychologists who became prominent in the history books, Murchison was not an influential theorist or researcher. Instead, he was an extremely active organizer, publisher, and editor. Murchison received his Ph.D. in social psychology from Johns Hopkins University in 1923. He taught at Clark University from 1923 to 1936. During most of this time he served as the chair of the psychology department.
