Alfred Adler
When he was halfway through that course of study, he quit and entered advanced studies at the Alfred Adler Institute of Chicago (now Adler University) in downtown Chicago to study Adlerian psychology. Rudolf Dreikurs, a protégé of Alfred Adler, founded the Alfred Adler Institute of Chicago. Cox studied there part-time from 1963 through 1975, while teaching sociology at Wheaton College for three years and at the same time launching his management consulting career.
