He initiated the systematic observation of his patients that led to his stellar research career, including an international reputation in cardiology, discovery of novel and important insights into heart rhythms, the use of digitalis, and a knighthood. At the height of his career in London, he returned to establish the Institute for Clinical Research in St Andrews at the age of 64.
