Alexander Henry Halliday, M.D. — Son of the Rev. Samuel Haliday, a Presbyterian Minister of Belfast, where he was born about 1728 — or in 1730, as has been said. He was, for nearly half a century, the most popular physician in Ulster. He was a frequent correspondent of Lord Charlemont's, and a number of his letters will be found in Hardy's life of latter, and in the Charlemont MSS. His tragedy, on the subject of Lucius Junius Brutus, was never published, though Charlemont had a high opinion of it. Dr. Haliday also wrote many satirical and other pieces, a few of which will be found in Belfast Magazine for September and October, 1810, and June, 1811. He died in Belfast on April 28, 1802, aged 72. A namesake of his published some works on natural history between 1839-1854.
