Hans Jürgen Eysenck

German-British professor of psychology and an astrological researcher. The most prolific writer on psychology of his era, he was the editor of many papers and books and the author of some 700 journal articles and 30 books. The son of actor parents, he was raised primarily by his grandmother. He grew up to detest the Nazi regime and left Germany in 1934 for political reasons during the rise of the Third Reich to study psychology in London. He finished his Ph.D. during the early part of the war, while listed as an "enemy alien."

Eysenck established the new University of London Psychology Dept at Maudsley hospital. His work focused on personality and abnormal behavior, using the statistical method of factor analysis. Skeptical of the efficacy of psychoanalysis, he coined the term "behavior therapy."

He married and they had five kids. Eysenck died on 4 September 1997, London, England.
