Born at Antrim, Ireland on 28 February 1862 third son of William Jaques, a taxer, and his wife née Graves, he was educated privately before training at Liverpool Medical School. He transferred to King's College, London, qualified through the Conjoint Board, and served as house surgeon at King's College Hospital in 1901. He was clinical assistant and surgical registrar at the Royal Eye Hospital, Southwark, in 1903 and then settled as an ophthalmologist at Plymouth, becoming surgeon to the Royal Eye Infirmary there in 1908, and subsequently consulting surgeon. He practised privately at 20 Athenaeum Street. Jaques held advanced political views and advocated the nationalisation of medicine as early as 1909, two years before the introduction of Lloyd George's National Insurance scheme. He was a scholarly man and excellent public speaker, whose kindly and whimsical nature won the affection and esteem of his political opponents. He was Chairman of the Plymouth division of the British Medical Association 1911-18, and a Vice-Chairman 1918-22, and was President of the South-Western branch 1923-24. He was also President of the Plymouth Medical Society. During the war of 1914-18 he served in the RAMC at Plymouth with the rank of Captain. He was a member of the Royal Western Yacht Club. He married on 28 April 1906 Gabrielle Eldrid, who survived him, but without children. After retirement in 1930 he settled at Findon House, 38 Down View Road, Worthing, Sussex, and died on 20 September 1953 in Worthing Hospital, aged 91.
