Dr. Harold Mosak, one of the preeminent interpreters of Alfred Adler and his individual psychology, died June 1 at the age of 96.
Regarded internationally, Dr. Mosak wrote hundreds of articles and numerous books on the subjects. He also trained and supervised scores of Adlerians for more than 60 years until his retirement. He was among the first psychologists licensed in the United States, was a diplomate in clinical psychology (ABPP), and he was a life member and fellow of the American Psychological Association. He completed an A.B. in psychology and a Ph.D. in clinical psychology at the University of Chicago. He also served in the United States Army Air Force (1943-1946).
With his mentor Rudolf Dreikurs, and colleagues including Bernard Shulman, Dr. Mosak founded the Alfred Adler Institute – today Adler University – in 1952. The movement spread in 1967 as Minnesota Adlerian Society was formed, and in 1969 became the Alfred Adler Institute of Minnesota connected to the individuals in Chicago. Dr. Mosak was a frequent lecturer at the Adler Graduate School over the years.
In 2014, the Harold H. Mosak Adlerian Mastery Lab was collected and resides at the Adler Graduate School in Minnesota. The collection contains some 2000 items, mostly printed and published materials, correspondence, some press, and other ephemera related to the study and teaching of Adlerian psychology. The items in the collection, particularly in the Adler and the First Generations, document the earliest days of the study of psychology, though many materials reflect the changes the profession has seen. The items in the General Collection document development of psychological research and practice up to the present day, but the bulk of the collection relates to Dr. Mosak’s studies and teachings and includes much work from his contemporaries, including Dr. Rudolf Dreikurs, and scholarship that builds off Dr. Mosak’s work.
The Adler Graduate School community extends its condolences to the family of Dr. Mosak and is grateful for his many contributions.
