Erik Homburger Erikson (born Erik Salomonsen; 15 June 1902 – 12 May 1994) was a German-American developmental psychologist and psychoanalyst known for his theory on psychological development of human beings. He may be most famous for coining the phrase identity crisis. His son, Kai T. Erikson, is a noted American sociologist.
Despite lacking a bachelor's degree, Erikson served as a professor at prominent institutions, including Harvard, University of California (UC Berkeley), and Yale. A Review of General Psychology survey, published in 2002, ranked Erikson as the 12th most cited psychologist of the 20th century.
