The Lumleian Lectures are a series of annual lectures run by the Royal College of Physicians of London, started in 1582 and now run by the Lumleian Trust. The name commemorates John Lumley, 1st Baron Lumley, who with Richard Caldwell of the College endowed the lectures, initially confined to surgery, but now on general medicine. The work of William Harvey on the circulation of the blood was first announced by him in the Lumleian Lecture for 1616. By that time ambitious plans for a full anatomy course based on weekly lectures had been scaled back to a lecture three times a year.
