Born on 1 November 1875, the younger son of Thomas Jones, a consulting civil engineer who lived in Hanover Square and who was noteworthy for his land survey for the Cambrian Railway and for the Manchester Ship Canal, Seymour Jones studied medicine at St Thomas's Hospital from 1894, qualifying with the Conjoint Diploma in 1901. He was then appointed house surgeon to Sir Charles Balance, who was not only a senior consulting general surgeon but was also aural surgeon and who undertook important research into the problems of chronic otitis media and radical mastoidectomy. In 1903 Seymour Jones was admitted a Fellow and carried out postgraduate study in Politzer's aural clinic in Vienna. In 1904 he was appointed assistant surgeon to the Birmingham and Midland Ear and Throat Hospital, joining Colonel Frank Marsh and, later his son Frank, in general practice. During the first world war he served as captain RAMC (TA) acting as aurist to the 1st and 2nd Southern Military Hospitals. Retiring to Aberdovey in Merionethshire in 1937 he became an active member of the staff of hospitals in Towyn and Machynlleth until 1956. In 1953 he completed fifty years as a Fellow of the College and, on receiving the usual letter from the then President, Sir Cecil Wakeley, in his answer of thanks mentioned that he had smoked a pipe all his life and stressed the importance of hobbies. He was a well loved character in Birmingham and considered outstanding as an aural surgeon. After his retirement he was able to enjoy his hobbies, fly fishing, shooting and golf to the full. He died at the Eye and Ear Hospital in Southsea on 24 March 1966, aged 90, survived by his widow, who died on 21 April 1971, and a daughter and a son who is consultant in oto-rhino-laryngology in the Portsmouth and Poole Hospital Management Committee.
