Hippocrates is often referred to as the "Father of Medicine." He was an ancient Greek physician who lived during the Classical period, around 460–370 BC. Hippocrates is known for his contributions to the medical field, particularly his emphasis on careful observation and documentation of clinical cases. He established principles of ethics in medicine, which are encapsulated in the Hippocratic Oath, a foundational document for medical ethics even today. His approach shifted medicine away from superstition and mythology towards a more systematic and scientific perspective.
