Hippocrates (circa 460 BC – 370 BC) was one of the most significant physicians of ancient Greece, known as the “father of medicine.” Born on the island of Kos, he laid the foundation for medicine as a science based on logic and observation. Through the Hippocratic Collection, he introduced the principles of clinical observation and ethics into medical practice.

Hippocrates introduced the theory of the four humors and established the principles of medical ethics with the famous Hippocratic Oath, which binds physicians to act in the best interest of patients, maintaining integrity and confidentiality. His legacy continues to influence medicine today, making him an iconic and timeless symbol of medical science and ethics.
