Herophilos (/hɪˈrɒfɪləs/; Greek: Ἡρόφιλος; 335–280 – 255 BC), sometimes Latinized Herophilus, was a Greek physician deemed to be the first anatomist. 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 recorded his findings in over nine works which are all lost.
