Aristotle was an ancient Greek philosopher who wrote extensively on a sweeping range of topics, including physics, biology, logic, ethics, linguistics, and politics. He’s widely acknowledged to be one of the first genuine scientists in history, and his writings contributed to the development of whole new areas of study. Having trained under the Greek philosopher Plato at his Academy in Athens, Aristotle went on to become Alexander the Great’s tutor, and then later founded his own school in Athens called the Lyceum.
