Aaron T. Beck

A playground fall broke Aaron Beck's arm when he was seven. The bone became infected, the infection went septic, and the hospital stay cost him his place in school. He came out believing he was stupid and carrying a phobia of blood and injury he spent decades working on. His mother, a Jewish immigrant from Ukraine, had been chronically depressed since losing two children before he was born, one of them in the 1919 influenza pandemic. Beck was the youngest of the four who survived. He was valedictorian at Hope Street High School, took his degree at Brown in 1942 and his medical degree at Yale in 1946, and intended to be a neurologist. A shortage of psychiatry residents sent him into a rotation he did not want.

At Pennsylvania, where he joined the psychiatry department in 1954, Beck set out to put psychoanalysis on an experimental footing and tested its central claim about depression, that it was anger turned inward. His data refuted it. What depressed patients produced instead was a stream of unbidden appraisals of themselves, the world and the future, which he named automatic thoughts. The therapy he built from that treated the thoughts as the target: structured, time-limited, homework-based, written down in enough detail to be run as a clinical trial. In 1961 came the Beck Depression Inventory, which scored severity as a number.

Following his own evidence cost Beck his standing among the analysts. The American Psychoanalytic Association turned down his membership application in 1960, unconvinced that a brief therapy could do what he said it did, and turned him down again in 1961. Deferral was a routine instrument for enforcing orthodoxy, though Beck did not know that at the time and called the decision dumb. A fight over the Pennsylvania chair left him at odds with his closest friend in the department. In 1962 he took a sabbatical and went into private practice for five years. Through it he kept notebooks of self-analysis, writing out his own negative thoughts twice a day, rating how far he believed each one, and reworking them — the method he was proposing, run on himself.

He worked into his late nineties, turned 100 in July 2021, and died in his sleep at home in Philadelphia on November 1 that year. By then cognitive behavioral therapy was what public health systems and insurers reached for first across the English-speaking world, and the most tested psychotherapy in existence. Its critics say that is partly an artifact: a manualized, short, cheap treatment is far easier to test and to fund than an open-ended one, and several later meta-analyses have found the early effect sizes inflated by small studies and publication bias. Others argue it manages symptoms and leaves causes alone. His daughter Judith Beck co-founded the Beck Institute with him in 1994 and continues the work.
