WHO WAS HIERONYMUS FABRICIUS?

Hieronymus Fabricius was a distinguished anatomist and surgeon most famous for being William Harvey's tutor when he studied at Padua University. Fabricius was a keen and enthusiastic anatomist who made the observation that veins contain valves, but did not relate these to the circulation of the blood. At that time it was believed that blood was constantly being made and used up in line with the theories of Claudius Galen.
