Abū Bakr Muhammad ibn Zakariyyā al-Rāzī (known in the West by his Latinized name Rhazes) is considered one of the most original and accomplished of the medieval Muslim physicians. An impressive list of achievements is linked to his name: he pioneered the study of pediatrics, ophthalmology, synthesized laboratory acids, composed treatises on smallpox and measles, wrote voluminously in a number of scientific fields, and had extensive practical experience with treating patients.
