Ibn Zuhr was one of the greatest physicians and clinicians of the Muslim golden era and has rather been held by some historians of science as the greatest of them. Contrary to the general practice of the Muslim scholars of that era, he confined his work to only one field : medicine. This enabled him to produce works of everlasting fame.
As a physician, he made several discoveries and breakthroughs. He described correctly, for the first time, scabies, the itch mite and may thus be regarded as the first parasitologist. Likewise, he prescribed tracheotomy and direct feeding through the gullet and rectum in the cases where normal feeding was not possible. He also gave clinical descriptions of mediastinal tumors, intestinal phthisis, inflammation of the middle ear, pericarditis, etc.
Abu Marwan Abd al-Malik ibn Zuhr (Arabic: أبو مروان عبد الملك بن زهر) (also known as Ibn Zuhr, Avenzoar, Abumeron or Ibn-Zohr) (1091-1161) was an Arab Muslim physician, pharmacist, surgeon, parasitologist, Islamic scholar, and teacher.
Early life
He was born in Seville, and studied at the University of Cordoba. He belonged to the Banu Zuhr family, which produced five generations of physicians, including two female physicians who served the Almohad ruler Abu Yusuf Ya’qub al-Mansur. Ibn Zuhr was also the teacher of Averroes. He began his medical practice and training under his father, Abu’l-Ala Zuhr (d. 1131).
Flight from Seville
Around 1130, he fell out of favour of with the Almoravid ruler, Ali bin Yusuf bin Tashufin, and fled from Seville. He was however, apprehended and jailed in Marrakesh. Later in 1147 when the Almohad dynasty conquered Seville, he returned and devoted himself to medical practice and teaching. He died at Seville in 1161.
