Keith Simpson (pathologist)

Cedric Keith Simpson CBE FRCP FRCPath (20 July 1907 – 21 July 1985) was an English forensic pathologist. He was Professor of Forensic Medicine in the University of London at Guy's Hospital, Lecturer in Forensic Medicine at the University of Oxford and a founding member and President of the Association of Forensic Medicine. Simpson became renowned for his post-mortems on high-profile murder cases, including the 1949 Acid Bath Murders committed by John George Haigh and the murder of gangster George Cornell, who was shot dead by Ronnie Kray in 1966.

He pioneered forensic dentistry, and was prominent in alerting physicians and others in 1965 to a previously under-diagnosed form of child abuse that he termed battered baby syndrome (and, from 1967, battered child syndrome). Simpson wrote a standard textbook on forensic science and edited Taylor's Medical Jurisprudence, a basic work of reference of the British medical profession. Forty Years of Murder was Simpson's autobiography and became an international best-seller in the late 1970s. He was London's first forensic pathologist to be recognised by the Home Office, and in 1975 his long public service was recognised with the award of a CBE. Simpson had by then gained the reputation of having performed more post-mortems than any other pathologist in the world.
