Flavell, John H.

John H. Flavell was born on August 9, 1928 in Rockland, Massachusetts. He was one of three children (two sisters). Flavell joined the army in 1945; after two years he enrolled at Northeastern University in Boston, majoring in psychology. Graduating as valedictorian in 1951, Flavell chose to attend Clark University for graduate school over Harvard since Clark offered financial aid. This program emphasized the organismic-developmental theory of psychology. Flavell completed his M.A. in one year and finished his Ph.D. in 1955.

Flavell's first job was at the Veteran's Administration Hospital in Colorado. After three years, he took a position at the University of Rochester, becoming an associate professor in 1960. Flavell wrote The Developmental Psychology of Jean Piaget in 1963 in which he discussed the work of Piaget. This marked a significant event in the cognitive study of children.
