Abū-Marwān ʻAbd al-Malik ibn Abī al-ʻAlāʼ Ibn Zuhr (Latinized into Avenzoar, Abumeron or Abhomeron; 1091–1162 CE) or simply Ibn Zuhr, is an Arab Muslim physician and surgeon and perhaps the most famous Andalusi physician.
He is known for his emphasis on a more rational, empiric basis of medicine.
He was born at Seville (now southwestern Spain).
His famous book Al-Taysīr fil-Mudāwāt wal-Tadbīr ("Book of Simplification Concerning Therapeutics and Diet") is influential to the progress of surgery.
He also improves surgical and medical knowledge by keying out several diseases and their treatments.
Ibn Zuhr performs the first experimental tracheotomy on a goat.
He is thought to have made the earliest description of bezoar stones (essentially, hairballs) as medicinal items.
