He spent all his pro-fessional life at Guy’s Hospital and his name became a ‘householdword’ through his involvement in innumerable notorious murdertrials in Britain and overseas. He was made a Commander of theBritish Empire in 1975.He was a superb teacher, through both the spoken and the printedword.
