Bessel van der Kolk, born in 1943, is a Boston-based Dutch-American psychiatrist, author, researcher and educator whose work on post-traumatic stress stretches back to the 1970s. He is a professor of psychiatry at Boston University School of Medicine, president of the Trauma Research Foundation and a former president of the International Society for Traumatic Stress Studies – in short, one of the most institutionally established figures in his field.
His fame beyond that field rests on The Body Keeps the Score, a New York Times best-seller translated into forty-three languages. Honesty requires the caveat: scientists have criticised the book for promoting claims about trauma, memory, the brain and development that outrun the evidence. Its cultural reach, however, is beyond dispute.
