Erik H. Erikson
Born June 15, 1902; died May 12, 1994 at the age of 91.
Erik Homberger Erikson was a German-American psychoanalyst who trained with Anna Freud, specializing in child psychology, then emigrated to the United States. He taught at Harvard, engaged in various clinical papers, and expanded the scope of psychoanalytic theory to take more account of social, cultural, and other environmental factors. In 1950, he profoundly influenced the study of human development with the publication of the book Childhood and Society, in which he divided human development from childhood to old age into a life cycle of eight stages. His later work dealt with ethical issues in the modern world.
