Galen

Galen grew up in the Ancient Greek city of Pergamon (alternatively, Pergamum) which was a booming cultural center of the bygone era with a library surpassed only by the one at Alexandria. This and the ambitions of his father, Nicon, led to him becoming the greatest physician of his time. His most important additions to the field of medicine include his Theory of Opposites, the augmentation of Hippocrates's humoral physiological model, and the tremendous amount of treatises published on human anatomy and his observations of it.
