Sir Morell MackenzieBorn 7 Jul 1837; died 3 Feb 1892 at age 54. English laryngologist, who, as Britain's leading specialist,was at the centre of a bitter international controversy over the death of Emperor Frederick III of Germany. In his book, The Fatal Illness Of Frederick The Noble (1888), Mackenzie describes his care of laryngeal cancer in the Crown Prince, later Emperor Frederick the Noble. He had been accused of medical malpractice by German physicians following the emperor's death on 15 Jun 1888. The book not only decribes laryngology at the end of the 19th century, but also offers hidden insight into German history, as well as a soap opera complete with scheming and attempts at character assassination.
