To Kill a Mockingbird by Harper Lee is full of interesting characters who live in or near the town of Maycomb. In chapter four of the novel, we meet two of them, Mrs, Henry Lafayette Dubose and Cecil Jacobs. In chapter five we meet two more, Maudie Atkinson and Uncle Jack Finch.
Mrs. Dubose is a cantankerous old woman who lives near the Finches. She is not shy about expressing her racist views about the Finch children or their father in a very loud and direct fashion to Jem and Scout as they walk by her. Nevertheless, Atticus is polite to her and insists his children do the same. Eventually Atticus will say this about Mrs. Dubose:
"I wanted you to see what real courage is, instead of getting the idea that courage is a man with a gun in his hand. It's when you know you're licked before you begin but you begin anyway and you see it through no matter what. You rarely win, but sometimes you do. Mrs. Dubose won, all ninety-eight pounds of her. According to her views, she died beholden to nothing and nobody. She was the bravest person I ever knew."
Cecil Jacobs is a schoolmate and very minor character in the novel.
Miss Maudie is a key player in this novel, representing a kind of mother figure and mentor to both of the Finch children (who are without a mother), but particularly Scout. She reinforces the things Atticus is trying to teach his children as well as helps them get a perspective on things that happen in the story.
Uncle Jack is Atticus's younger brother and a physician. While he does not show up often in the novel, he is another voice of reason in the children's lives.
