Sir Thomas Grainger Stewart (23 September 1837, in Edinburgh – 3 February 1900, in Edinburgh) was an eminent Scottish physician who served as president of the Royal College of Physicians of Edinburgh (1889–1891), president of the Medico-Chirurgical Society of Edinburgh, president of the medicine section of the British Medical Association, and Physician-in-Ordinary to the Queen for Scotland. He was perhaps best known for describing the condition known as multiple neuritis as well as directing scientific attention in Great Britain to the deep reflexes. Source: Wikipedia (en)
