Briefly describe Atticus' character?

Atticus Finch

The father of Scout and Jem, Atticus is a lawyer and an extremely morally upright man who strives to deal with everyone fairly. Atticus is sometimes overly optimistic, but his unshakable hope in mankind and self-created role as the town 'do-gooder' sustain him. Atticus' wife died when Scout was very small, and he has raised his children only with the assistance of Calpurnia, his black housekeeper and cook.
