Erik Erikson (June 15, 1902 – May 12, 1994) was a prominent psychologist and psychoanalyst. He trained in psychoanalysis at the Vienna Psychoanalytic Institute and also studied the Montessori method.
He developed a theory of Psychosocial Development with 8 stages that bear a remarkable intellectual debt to the 4 Planes of development. I encourage you to take a few minutes to read this brief summary of the stages outlined below, and compare to these to the 4 Planes.
