c. 980 – June 1037

Ibn Sīnā, more commonly known by his Latinized name Avicenna, was a Persian polymath, who wrote almost 450 treatises on a wide range of subjects, of which around 240 have survived.

His most famous works are The Book of Healing, a vast philosophical and scientific encyclopaedia, and The Canon of Medicine (al-Qânûn fî al-tibb). The Canon of Medicine was translated into Latin in the 12th century, and in its Latin version, it functioned as the standard medical work in medieval Western universities for four centuries, becoming the most successful textbook ever written.

His other writings include philosophy, astronomy, alchemy, geology, psychology, Islamic theology, logic, mathematics, physics, as well as poetry. He is regarded as the most famous and influential polymath of the Islamic Golden Age.

The Royal Pharmaceutical Society have Ibn Sina on their coat of arms.
