Hippocrates (460 BC - 370 BC)
An ancient Greek physician who is considered to be one of the most outstanding figured in the history of medicine. He is continually recognized for his lasting contributions to the field and the Hippocratic School of Medicine, an intellectual school that revolutionized medicine in ancient Greek and distinguishing medicine apart from other fields, thus, establishing medicine as a profession. However, little is actually known about what Hippocrates thought, wrote and did, but is portrayed as the paragon of the ancient physician. He is particularly credited with advancing the study of clinical medicine, summarizing the medical knowledge of previous schools of thought, and prescribing practices for physicians through the Hippocratic Corpus and other works.
