"Ibn Sina[a] (c. 980 22 June 1037), commonly known in the West as Avicenna (/ˌævɪˈsɛnə, ˌɑːv-/ A(H)V-ih-SEN-ə

, was a preeminent philosopher and physician of the Muslim world.[2][3] He was a seminal figure of the Islamic Golden Age, serving in the courts of various Iranian rulers,[4] and was influential to medieval European medical and Scholastic thought.[5]
Often described as the father of early modern medicine,[6][7][8] Avicenna's most famous works are The Book of Healing, a philosophical and scientific encyclopedia, and The Canon of Medicine, a medical encyclopedia[9][10][11] that became a standard medical text at many medieval European universities[12] and remained in use as late as 1650.[13]
Besides philosophy and medicine, Avicenna's corpus includes writings on astronomy, alchemy, geography and geology, psychology, Islamic theology, logic, mathematics, physics, and works of poetry.[14] His philosophy was of the Peripatetic school derived from Aristotelianism,[15] of which he is considered among the greatest proponents within the Muslim world.[5]
Avicenna wrote most of his philosophical and scientific works in Arabic but also wrote several key works in Persian; his poetry was written in both languages. Of the 450 works he is believed to have written, around 240 have survived, including 150 on philosophy and 40 on medicine.[15]"..... (more at link)
