William Harvey

William Harvey (April 1, 1578-June 3, 1657) was an English physician whose writing On the Motion of the Heart and Blood first described in detail the circulation of blood within the body. He was appointed a Lumleian lecturer in 1615 and served as a physician to King James I starting in 1618. He died in the home of his brother Eliab, probably due to a cerebral hemorrhage.
