Although his education was interrupted for military service during the First World War, Allport earned his A.B. degree in 1919, with majors in
philosophy and economics. Following a year of teaching English and sociology at Robert College in Istanbul, Turkey, Allport returned to Harvard with a fellowship to study psychology. He was influenced both by his brother Floyd and by the noted experimental psychologist Hugo Münsterberg. He coauthored his first publication, “Personality Traits: Their Classification and Measurement,” with his brother in 1921. Allport received his M.A. degree in 1921 and his Ph.D. in 1922, for his study of personality traits under the direction of Herbert S. Langfeld.
A Sheldon Traveling Fellowship enabled Allport to spend two years studying in Berlin and Hamburg, Germany, and in Cambridge, England. He then returned to Harvard as an instructor in social ethics from 1924 to 1926. Allport married Ada Lufkin Gould in 1925. Their
son, Robert Bradlee Allport, grew up to become a pediatrician. After four years as an assistant professor of psychology at Dartmouth College, Allport returned to Harvard where he remained for the rest of his career.
