Narrated by Erikson's colleague, Margaret Brenman-Gibson, Ph.D. and Ruthie Mickles, Ph.D. Using archival materials and newly shot footage, this film introduces students to the rich wisdom of Erik H. Erikson. Best known for his identification of the eight stages of the life cycle, Erikson spent a lifetime observing and studying the way in which the interplay of genetics, cultural influences and unique experiences produces individual human lives. This film combines biographical information about Erikson with his theoretical proposals to give students an understanding of the relationship between the life experience of a theorist and the work that is produced.
