Hippocrates was a Greek physician born in 460 BC on the  island of Cos, Greece. He became known as the founder of medicine  and was regarded as the greatest physician of hisâ¦ time. He based  his medical practice on observations and on the study of the human  body.
This is another important part of why Hippocrates is still considered to be one of the most important people in the history of medicine. Hippocrate's ideas were a strange mixture of commonsense and factual inaccuracies. His suggestions about diet and exercise are as valid today as they were 2,400 years ago and also his use of observation.
