Sir Morell Mackenzie (7 July 1837 – 3 February 1892) was a British physician, one of the pioneers of laryngology in the United Kingdom. Biography Morell Mackenzie was born at Leytonstone, Essex, England on 7 July 1837. He was the eldest of nine children of Stephen Mackenzie (1803-1851), a general practitioner and surgeon, and Margaret Frances (died 1877), daughter of wine merchant Adam Harvey, of Lewes, East Sussex. He was educated at Dr Greig's school in Walthamstow and at King's College London. After going through the medical course at the London Hospital and becoming a member to the Royal College of Surgeons in 1858, he studied abroad in Paris, Vienna and Budapest where he learned the use of the newly invented laryngoscope under Johann Czermak. Returning to London in 1862, he worked at the London Hospital and earned his degree in medicine. In 1863 he won the Jacksonian prize at the Royal College of Surgeons for an essay on the Pathology and Treatment of Diseases of the Larynx: The Diagnostic Indications to include the Appearance as Seen in the Living Person. He was the first to use the terms abductors and adductors to describe the muscles that govern the opening and closing of the glottis. He then devoted himself to becoming a specialist in diseases of the throat. In 1863 the Hospital for Diseases of the Throat in King Street, Golden Square, was founded, largely owing to his initiative, and by his work there and at the London Hospital (where he was one of the physicians from 1866 to 1873) Morell Mackenzie rapidly became recognized throughout Europe as a leading authority, and acquired an extensive practice. A plaque at 32 Golden Square, unveiled in May 1995, commemorates the original hospital. His reputation grew even more with the publication of three important books, which became the founding stones of the new specialty of laryngology: The Use of the Laryngoscope in Diseases of the Throat (1865). Growths in the Larynx (1871). Diseases of the Nose and Throat (1880 and 1884). In 1887 Mackenzie was one of the founders of the Journal of Laryngology and Rhinology and of the British Rhino-Laryngological Association. So great was his reputation that in May 1887, when the crown prince of Germany (afterwards the Emperor Frederick III) was attacked by the affection of the throat of which he ultimately died, Morell Mackenzie was specially summoned to attend him.
