Abu Bakr al-Razi (Razi) was Persian polymath in the studies as physician, alchemist, and philosopher in the 9th and 10th centuries. He was an important figure in medicine with numerous discoveries in compounds and chemicals including alcohol and sulfuric acid.

As chief physician of Baghdad and Ray hospitals, he was an early proponent of experimental medicine and was known for serving patients, both rich or poor. His experiments included the study of treatment for meningitis as well as early pharmacology with the use of mercurial ointments.

Razi was a prolific author writing over 200 books including a 23-volume of medical textbooks documenting the foundation of gynecology, obstetrics, and ophthalmology. Many of his works related to his original observations on diseases and therapies research were compiled after his death.

A statue of Razi is seated alongside 3 other revolutionary polymath scholars, Abu Ali Sina, Biruni and Omar Khayyam in the Persian Scholars Pavilion located in the Memorial Plaza at the United Nations International Center located in Vienna.

Razi spent the last years of his life in his native town of Rey suffering from glaucoma which ultimately resulted in total blindness.
