Born in Pergamum (part of present-day Turkey) around the year 130 A.D., Galen lived most of his life in Rome as the doctor of the imperial court who also cared for members of noble families. Eighty-three of his treatises on medicine have survived, including writings on the nervous system, hygiene, the practice of bloodletting, etc., as well as on pharmacology. He is in fact considered the father of pharmacology. He died sometime around 215-16 A.D.
