Erik H. Erikson
Personality development, in Erik H. Erikson’s view, occurs through a series of identity crises that occur in stages that must be overcome and internalized.
Erik H. Erikson immigrated to the United States in 1933, where he practiced child psychoanalysis and joined the Harvard Medical School faculty. In 1936 he moved to Yale, and in 1938 he began his first studies of cultural influences on psychological development. He later taught at U.C. Berkeley, but left in 1950. In his view, personality development takes place through a series of identity crises.
