# Dictionary of National Biography, 1885-1900/MacCormac, Henry

​MACCORMAC, HENRY, M.D. (1800–1868), physician, born at Fairlawn, co. Armagh, in 1800, was son of Cornelius MacCormac, an officer in H.M. navy. Having studied at Dublin, Paris, and Edinburgh, he graduated M.D. in the last university in 1824, and in the same year became a licentiate of the Royal College of Surgeons of Edinburgh. He then determined to travel and journeyed to Africa. After visiting the Cape of Good Hope, he went to Sierra Leone by land, and nearly succumbed to an attack of jungle fever on the way. He subsequently made two voyages to the United States. Soon afterwards he commenced practice as a physician in Belfast, where his abilities were recognised, and he was appointed physician to the Royal Hospital, then known as the Belfast Fever Hospital. In 1832 Asiatic cholera prevailed in Belfast, and MacCormac was appointed to take charge of the cholera hospital, and received a handsome testimonial and the thanks of the citizens for his exertions. He was subsequently chosen visiting physician to the Belfast District Lunatic Asylum, an office which he held until his death. He soon brought about a marked change in the condition of the inmates by his insistence upon more generous dietary, and during another epidemic of cholera there was not a single death in the asylum, which was ascribed to careful sanitation and the prophylactic administration of diluted mineral acids to the patients. MacCormac was also for a time professor of the theory and practice of medicine in the Royal Belfast Institution. In 1857 he was a candidate for the chair of materia medica in the Queen's College, Belfast. For many years he enjoyed an extensive consultation practice, but he gradually became more devoted to literary and scientific study, and about 1866 he relinquished the active duties of his profession and devoted himself to writing books. He is said to have possessed a knowledge of at least twenty languages, and was specially devoted to the study of comparative philology. In his medical treatises the topics on which he most insisted were his method of prevention and treatment of consumption and the danger of inhaling pre-breathed air. He urged very strongly the necessity of maintaining the purity of the air. He was also an ardent advocate of active physical exercise in the preservation of health. MacCormac died on 26 May 1886 at Fisherwick Place, Belfast. By his wife Mary, daughter of William Newsam, he was the father of Sir William MacCormac, the eminent surgeon.
