The answer is "Erik Erikson".
Erik Erikson was an ego psychologist who created a standout amongst the most prominent and compelling theories of development. While his theory was affected by psychoanalyst Sigmund Freud's work, Erikson's hypothesis focused on psychosocial improvement as opposed to psychosexual advancement. Erikson trusted that identity created in a progression of stages. Not at all like Freud's hypothesis of psychosexual stages, Erikson's hypothesis depicted the effect of social experience over the entire life expectancy.
