What is the nickname of the reclusive neighbor Arthur Radley? He is known as Boo Radley.

Arthur “Boo” Radley is the Finch family’s reclusive neighbor in To Kill a Mockingbird. Scout and Jem first know him through frightening stories told by Maycomb residents, who portray him as a dangerous and unnatural figure. Because Boo rarely leaves his house, the children’s imagination fills in the details they do not know.

As the story develops, Boo’s actions quietly contradict the town’s rumors. He leaves small gifts for Scout and Jem in a tree’s knothole and watches over them from a distance. His intervention near the end of the novel protects the children from Bob Ewell, revealing that the supposedly frightening neighbor is compassionate and courageous.

Boo’s nickname is not his legal name: Arthur Radley is the character’s given name. He is also not Atticus Finch, Dill Harris, or Scout Finch. The mockingbird image connects to Boo as well as Tom Robinson because both are vulnerable figures harmed by other people’s unjust assumptions.
