Dr. David S. Bell, neuropsychiatrist, trained in Sydney, Australia, from 1955 and in London in 1961-2 at Queen Square as clinical assistant to Dr. Eliot Slater before returning to take charge of the Psychiatric Research Unit, which combined neurosurgery and neurology with the mental health disciplines. He took a special interest in epilepsy and drug addiction. Along the way he developed a therapeutic community and spent a great deal of time in group therapy. Moving into private practice in 1970, he turned his interest in neuropsychiatry to the forensic assessment of head injury. He was a creature of his times, described in his autobiography “Welcome to the Loony Bin: 55 Years in Psychiatry and the Law” available and open for comment on this site.
