Engraving by T Cook after a painting attributed to W v Bemmel, c 1657, of William Harvey MD, FRCP (1578-1657). Attached to St Bartholomews Hospital, Harvey was the physician of both James I and Charles I. He is best known for discovering the circulation of the blood, made public in 1616, but he also superintended the physical examination of women accused of witchcraft, and built a library for the Royal College of Physicians.
