Donald Craig Norris was born in London on 23 September 1892 and was educated at Aske's Hatcham School, the London Hospital, and the University of Paris. In the first world war he served as a stretcher bearer in the French Army and also in the Servian Red Cross during the typhus epidemic in 1915 for which he was awarded the Order of St Sava. He came home to qualify with the Conjoint Diploma in 1916, and then joined the RAMC and saw service in India, Mesopotamia, East Africa and France. After the war he returned to the London Hospital and took the FRCS in 1921 and the London MB BS in 1922, with honours in surgery and forensic medicine. For two years he was resident medical officer at Poplar Hospital for Accidents where he became involved in medico-legal work which ultimately became his special interest in preference to clinical surgery. He took the MD degree in 1924, and joined a city partnership. He later became medical officer to the Bank of England, chief medical officer of the Metropolitan Water Board and Lea Conservancy Board, and medical officer to various insurance companies. In 1936 he qualified as barrister-at-law at the Inner Temple. Norris was a man of wide interests including rehabilitation and industrial welfare, and was president of the Assurance Medical Society and of the Hunterian Society. His medico-legal interests led to his becoming associate editor of the Medico-Legal Journal. In 1923 he married Dr Helene Righthouse, who died after a long illness in 1958. When he died in the London Hospital on 17 January 1968 he was survived by his son who was also a doctor.
