William Harvey - The Circulation of Bloodthe body had already lasted 1400 years. Blood-letting continued to be a standard practice, as doctors believed many illnesses were caused by an over-supply of blood in the body. As time went by, and more discoveries were made, Harvey's work became undisputed. In 1651, Harvey wrote that animals did not spontaneously generate, that life began from an egg. He theorized the joining of a sperm and egg as the beginning of life. Two centuries would pass before microscopes were capable of seeing a mammalian egg. Many of his papers were lost when a fire ripped through the library at the College of Physicians, but some remain and are on exhibit at the British Museum. William Harvey died June 3, 1657. William Harvey Hospital in Ashford is named for him, as well as the Harvey Grammar School in Folkestone.
