Herophilos (Ancient Greek: Ἡ�όφιλο ς), sometimes Latinized Herophilus (335-280 BC), was a Greek physician. Born in Chalcedon, he spent the majority of his life in Alexandria. He was the first scientist to systematically perform scientific dissections of human cadavers and is deemed to be the first anatomist. Herophilos recorded his findings in over nine works which are all lost. He is most famous for his invention of the Scientific Method. Together with Erasistratus he is regarded as a founder of the great medical school of Alexandria.
