Erik Erikson, pioneer of psychosocial development, passed away on May 12, 1994 at the age of 91. Erikson was a Viennese-born American psychologist and psychoanalyst who crafted the influential theory of psychosocial development. His theory outlined the eight stages of development -- trust vs. mistrust, autonomy vs. shame and doubt, initiative vs. guilt, industry vs. inferiority, identity vs. role confusion, intimacy vs. isolation, generativity vs. stagnation, and finally, integrity vs. despair. This uniquely comprehensive developmental theory has been influential in psychology and remains one of the major contributions to the field. In addition to his numerous books and papers on psychosocial development, Erikson wrote extensively on topics such as dying and was a leader in the field of life-span development. He was a professor of human development at Harvard University, and he received several honorary degrees from prestigious educational institutions. In addition, Erikson won numerous awards for his work, including two distinguished awards from the American Psychological Association and the American Psychiatric Association, and the Erasmus Prize. Erikson is survived by his wife and four children. He was predeceased by his older brother.
