c.460 - c.375 BC
Greek Physician
Hippocrates of Cos, is traditionally called the 'Father of Medicine'.

He maintained that disease had only natural causes, and took the treatment of disease out of the hands of religion. His theories of medicine are summed up in the 'Corpus Hippocratium', a collection of 70 works, the oldest surviving complete medical books.

The 'Hippocratic Oath' named after him, gave the medical profession a sense of duty which it never lost.
