Raymond Corsini´s training was diverse. He received a BA and MA at the City College of New York, then did his doctoral training at Syracuse University, Cornell University, University of California, University of Wisconsin (all during the time of his work as a prison psychologist), and finally obtained a Ph.D. at age 41 from the University of Chicago under Carl Rogers. He met and interacted with J.L. Moreno, Fritz Perls, Victor Frankl, and Albert Ellis, among others, but his main teacher was Rudolf Dreikurs, an Adlerian. He had three separate careers: as a prison psychologist for 15 years, then an industrial psychologist for ten years, and finally in private practice of psychotherapy and counseling for 30 years. He taught courses at over a dozen universities and full time at the University of Chicago, Illinois Institute of Technology, and the University of California at Berkeley. He has published over 60 books under 43 titles, including four encyclopedias and the most complete dictionary of psychology, and has written or edited 18 books in counseling or psychotherapy.
