Dictionary of National Biography, 1885-1900/Douglas, Alexander (1738-1812)
DOUGLAS, Sir ALEXANDER (1738–1812), physician, son of Sir Robert Douglas of Glenbervie [q. v.], author of ‘The Peerage of Scotland,’ studied medicine at Leyden (1759), and was admitted M.D. of St. Andrews in 1760. He became a fellow of the Edinburgh College of Physicians, and also a licentiate of the London college in 1796. He was physician to the king's forces in Scotland (Jervise, l. c.), and lived at Dundee. He married Barbara, daughter of Carnegy of Finhaven. His only son, Robert, died in 1780. Thus the baronetcy became extinct by the death of Douglas on 28 Nov. 1812. He is said to have been ‘a physician of eminence,’ but he left no works.
