Aristotle

Aristotle was a scholar. Barbara Wright encountered him on the steps of a library in Egypt. He was holding an anachronistic book that she tried to take from him. (PROSE: The Book of Shadows)

He was tutor of Alexander the Great when he was a boy. Alexander was so impressed with him that, as an adult, he did not wipe out the Greeks, though he did enslave them. (AUDIO: Mask of Tragedy)

Aristotle received a namesake in the form of a spaceship which served as a command ship of the Combined Galactic Resistance. (TV: Into the Dalek)
