Ackley is a student who lives in the adjoining room to Holden and Stradlater’s room at Pencey Prep. A peculiar and rather annoying young man, Ackley has terrible personal hygiene, bad skin, and unclean teeth. For this reasons, not many people like him, and Ackley’s behavior doesn’t help this situation, since he often lingers and acts like he dislikes people even though it’s obvious he wants them to pay attention to him. This is what he does to Holden on Holden’s last night at Pencey Prep. When Holden and Stradlater get into a fight, Holden retreats into Ackley’s room just because he wants some company, but he finds himself too annoyed by Ackley’s presence to remain in the room, so he decides to leave Pencey Prep and travel on his own to New York City.
