Hippocrates

Hippocrates of Cos (Ἱπποκράτης) (c. 460–c. 370BCE) was an ancient Greek physician who has come to be acknowledged as the Father of Medicine, and who gave his name to the Hippocratic Oath.

Hippocrates founded a school of medicine known by his name, and advocated a basic approach to the diagnosis and treatment of disease that still has applications in modern medicine: "The code of conduct for doctors outlined in the Hippocratic Oath, a vow commonly taken by modern doctors", remains an ethical guideline in medicine.
