The elder son of Walter Augustus Hume, who practised for many years in Hackney. The family came of the same Scottish stock as David Hume (1711-1776), the philosopher and historian. He received his medical education at St Bartholomew's Hospital, where he gained the Matthews Duncan and Bentley Prizes and was President of the Abernethian Society. For a short time he was House Physician at the East Sussex Hospital, Hastings, but, returning to St Bartholomew's Hospital, he filled the offices of Resident Anaesthetist, House Surgeon to Sir D'Arcy Power, Ophthalmic House Surgeon to W H Jessop and T Holmes Spicer, and Assistant Demonstrator of Anatomy. Glycosuria prevented him from applying for service abroad, but in 1915 he received a temporary commission as Major in the RAMC and acted until 1919 as Surgeon Specialist to the Norfolk War Hospital, with charge of 1040 beds. During this time he acted as instructor to American and British doctors before they were sent to the front. From 1919-1922 he was Superintendent of two Ministry of Pensions Hospitals at Exeter, and in 1923 he settled in practice at Bangor, becoming Surgeon to the Carnarvonshire and Anglesey Infirmary. He married in 1915 Dorothy Anne Streeter, who survived him with a daughter. He died instantaneously from a first attack of angina pectoris at The Vron, Bangor, on February 12th, 1929. Hume was a reliable surgeon, a good operator, and a fine teacher. He was a skilled yachtsman and possessed of considerable musical ability, for he played the flute in Mrs Gough's and the Normal College orchestras.
