Abu ʿAli al-Ḥusayn ibn ʿAbd Allah ibn Sina (c. 980 in Afshana near Bukhara, Khorasan – 1037 in Hamedan), also known by his Latinized name Avicenna (Gr. Αβιτξιανός), was a Persian Muslim polymath: an astronomer, chemist, logician, mathematician, physicist, poet, scientist, theologian, statesman, soldier, and foremost physician and philosopher of his time.
He wrote some 450 books on a wide range of subjects, many of which concentrated on philosophy and medicine. His most famous works are The Book of Healing and The Canon of Medicine, which was a standard medical text at many Islamic and European universities up until the 18th century. Ibn Sina developed a medical system that combined his own personal experience with that of Islamic medicine, the medical system of Galen, Aristotelian metaphysics, and ancient Persian, Arabian and Indian medicine. Ibn Sina is regarded as the father of modern medicine, particularly for his introduction of systematic experimentation and quantification into the study of physiology, and for his discovery of the contagious nature of diseases. He is also considered the father of the fundamental concept of momentum in physics.
George Sarton, the father of the history of science, wrote in the Introduction to the History of Science:
“One of the most famous exponents of Muslim universalism and an eminent figure in Islamic learning was Ibn Sina, known in the West as Avicenna (981-1037). For a thousand years he has retained his original renown as one of the greatest thinkers and medical scholars in history. His most important medical works are the Qanun (Canon) and a treatise on Cardiac drugs. The ‘Qanun fi-l-Tibb’ is an immense encyclopedia of medicine. It contains some of the most illuminating thoughts pertaining to distinction of mediastinitis from pleurisy; contagious nature of phthisis; distribution of diseases by water and soil; careful description of skin troubles; of sexual diseases and perversions; of nervous ailments.
