Jean Louise “Scout” Finch - The narrator and protagonist of the story. Scout lives with her father, Atticus, her brother, Jem, and their black cook, Calpurnia, in Maycomb. She is intelligent and, by the standards of her time and place, a tomboy. Scout has a combative streak and a basic faith in the goodness of the people in her community. As the novel progresses, this faith is tested by the hatred and prejudice that emerge during Tom Robinson’s trial. Scout eventually develops a more grown-up perspective that enables her to appreciate human goodness without ignoring human evil.
Atticus Finch - Scout and Jem’s father, a lawyer in Maycomb descended from an old local family. A widower with a dry sense of humor, Atticus has instilled in his children his strong sense of morality and justice. He is one of the few residents of Maycomb committed to racial equality. When he agrees to defend Tom Robinson, a black man charged with raping a white woman, he exposes himself and his family to the anger of the white community. With his strongly held convictions, wisdom, and empathy, Atticus functions as the novel’s moral backbone.
Jeremy Atticus “Jem” Finch - Scout’s brother and constant playmate at the beginning of the story. Jem is something of a typical American boy, refusing to back down from dares and fantasizing about playing football. Four years older than Scout, he gradually separates himself from her games, but he remains her close companion and protector throughout the novel. Jem moves into adolescence during the story, and his ideals are shaken badly by the evil and injustice that he perceives during the trial of Tom Robinson.
Arthur “Boo” Radley - A recluse who never sets foot outside his house, Boo dominates the imaginations of Jem, Scout, and Dill. He is a powerful symbol of goodness swathed in an initial shroud of creepiness, leaving little presents for Scout
