Hippocrates is known as the "Father of Medicine." He was an ancient Greek physician who lived around 460 to 370 BCE. He is credited with laying the foundations of scientific medicine, significantly influencing the practice of medicine and establishing ethical standards that practitioners still follow today, including the Hippocratic Oath. Hippocrates emphasized the importance of observation and documentation in diagnosing and treating illnesses. His teachings and texts, compiled in the Hippocratic Corpus, helped shape the principles of Western medicine and promoted the idea that diseases had natural causes, challenging the prevalent belief in supernatural explanations at the time.
