Henry was educated at University College and at the London Hospital, where he took the diplomas of the Society of Apothecaries in 1890 and the Conjoint Board in 1892. After a resident hospital appointment he went on several voyages to the East as surgeon in the P & O service. He was then in general practice for several years in Kensington, retiring in 1905. When war broke out Henry immediately returned from a riverside holiday to offer his services at the War Office for a year abroad with the R.A.M.C. He embarked on 22nd August 1914, entering the war in France. He was first attached to No 10 General Hospital, then later served with the 12th Field Ambulance. After his contract ended he again offered his services and was appointed to the Convalescent Hospital, Summerdown Camp, Eastbourne. While attending to his duties there he developed uremia, the result of a progressive renal and heart disease, reported as being due to the strains of active service. He died at his home in Oakwood Court, Kensington of acute edema of the lungs. Henry was the son of Robert Slade Jones; and the husband of Lilian K Rutherford Jones.
