Born at Little Beck, Westmorland, the son of John Hall, and of Isabel, daughter of T Fothergill. He was educated at Appleby Grammar School and at Guy's and St Thomas's Hospitals, joined the Army in Flanders four days after Waterloo, and was posted for duty to a General Hospital in Brussels. He was principal medical officer on active service in Kafraria in 1847 and 1851, and was on continuous duty in the Crimea without a day's absence from June, 1854, to July, 1856; he was made KCB in 1856, with mention in dispatches, an Officer of the Legion of Honour, and of the 3rd class of the Medjidie. He then retired on half pay as Inspector-General of Hospitals. He defended the services of the army medical officers in the Crimea in two pamphlets published in 1857 and 1858. He contended that the sanitary state of the Army had been in great part remedied before the Commission got to work, that the Commission accomplished little, and that with difficulty, but enough to show how the medical officers had been hampered by the exigencies of the service. He married in 1848 Lucy Campbell, daughter of Henry Hackshaw, and widow of Duncan Sutherland, of St Vincent, West Indies, and died at Pisa on January 17th, 1866.
