About Aaron T. Beck

Aaron Temkin Beck is an American psychiatrist who is professor emeritus in the department of psychiatry at the University of Pennsylvania. He is regarded as the father of cognitive therapy, and his pioneering theories are widely used in the treatment of clinical depression. Beck also developed self-report measures of depression and anxiety, notably the Beck Depression Inventory (BDI) which became one of the most widely used instruments for measuring depression severity.
Beck is noted for his research in psychotherapy, psychopathology, suicide, and psychometrics. He has published more than 600 professional journal articles, and authored or co-authored 25 books. He has been named one of the "Americans in history who shaped the face of American Psychiatry," and one of the "five most influential psychotherapists of all time" by The American Psychologist in July 1989. His work at the University of Pennsylvania inspired Martin Seligman to refine his own cognitive techniques and later work on learned helplessness.

Beck is currently the President Emeritus of the non-profit Beck Institute for Cognitive Behavior Therapy which he set up with his daughter in 1994
