Humans have long sought advice from those with knowledge or skill in healing. Paleopathology and other historical records, allow an examination of how ancient societies dealt with illness and outbreak. Rulers in Ancient Egypt sponsored physicians that were specialists in specific diseases. Imhotep was the first medical doctor known by name. An Egyptian who lived around 2650 B.C., he was an adviser to King Zoser at a time when Egyptians were making progress in medicine. Among his contributions to medicine was a textbook on the treatment of wounds, broken bones, and even tumors.
