Born at Vinossington on 16 October 1887, the third child of the Rev J H M de Mowbray and the elder child of his second wife Ann Barbara Lakin. He was educated at Marlborough 1901-05 and at St Thomas's Hospital, where he served as house surgeon, casualty officer, and resident anaesthetist. He was also house surgeon at the Royal Hampshire County Hospital at Winchester. War having broken out in 1914 soon after he had qualified, he served for a year at the British Red Cross Hospital at Netley, and took the Fellowship in December 1914. He then served for three and a half years, with the rank of captain, RAMC, at No 34 General Hospital, Deolali, India, acting as surgical specialist and officer in charge of the surgical division. On return to civil life he settled at Lymington, Hants in partnership with F H Maturin, MRCS. Later he took into partnership H L Hodgkinson, MRCS of Milford, K W Martin, MRCS of Brockenhurst, G R S Stewart, MRCS, and B M Thornton, BM, both of Lymington. De Mowbray carried out with great ability the surgical work of this large firm, which covered much of the New Forest district. He was surgeon to Lymington and District Hospital, and to Milford-on-Sea War Memorial Hospital, and consulting surgeon to Fenwick Cottage Hospital at Lyndhurst. Two years before his death he suffered from a coronary thrombosis, but recovered, and went back to full work as senior partner of his firm. De Mowbray married in 1915 Evelyn Mary Miles, who survived him with four sons. He died in London on 24 September 1945, aged nearly 58. De Mowbray had lived at Grosvenor House, High Street, Lymington, where the garden overlooked the Solent and the Isle of Wight. He was a good-looking man, who loved horses and dogs, and was a skilled maker and carver of furniture.
