Abu Marwan Abd al-Malik ibn Zuhr, the father of experimental surgery

16-Jul-09

Abu Marwan Abd al-Malik ibn Zuhr 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.

Abu Ja'far Muhammad ibn Musa al-Khwarizmi

Al-Khwarizmi was born in the epicentre of an Islamic empire which then stretched from the Mediterranean to India. This was a very fortuitous time for Arabic learning. The rulers of the Abbasid dynasty who were leading this huge empire, founded an academy in Baghdad called the House of Wisdom where the learned men collected and translated all the scientific works that they could get hold of. House of Wisdom had a large library – first famous library established after the library of Alexandria was destroyed.

Al-Khwarizmi was one of the learned men who worked in the House of Wisdom. His interests lied in the fields of algebra, geometry, astronomy and geography. His now most famous work is that from which we got the name for algebra itself – Hisab al-jabr w’al-muqabala.

Abu Ja’far Muḥammad ibn Musa al-Khwarizmi (c. 780, Khwarizm – c. 850) was a Persian mathematician, astronomer, and geographer, who worked most of his life as a scholar in the House of Wisdom in Baghdad.

His Algebra was the first book on the systematic solution of linear and quadratic equations. Consequently he is considered to be the father of algebra, a title he shares with Diophantus. Latin translations of his Arithmetic, on the Indian numerals, introduced the decimal positional number system to the Western world in the twelfth century. He revised and updated Ptolemy’s Geography as well as writing several works on astronomy and astrology.
