Abe the Teacher was a prominent human in Caesar's new Ape City. Named simply 'Teacher' for so long that he had almost forgotten his real name, he was given responsibility for educating the apes in basic reading and writing. His class consisted of young chimps and orangutans (including Cornelius) and older, less literate gorillas (including Aldo), but no humans. Teacher's place in society may have been slightly higher than other humans - only he and his friend MacDonald seem to have been allowed to dress in a pre-revolution clothes and remain clean-shaven - but he did not have the kind of influence MacDonald held.
