Greek physician Hippocrates (c. 460-370 BC), who is generally considered to be the father of medicine, although little is actually known about him. His influence survives in the Hippocratic oath, a code of medical ethics some medical students take on completion of their training. He founded a medical school on the Aegean island of Cos, where his ideas on medical conduct and practice were implemented. He advocated a rational approach to medicine, believing that disease was caused by physical phenomenon and not by the interference of the gods.
