Are there any quotes or passages that lead you to think Harper Lee was telling her life through Scout?
Although Harper Lee has long claimed that her novel of Southern life in the 1930s, To Kill a Mockingbird, is not autobiographical, there are many similarities between the young heroine, Scout, and her own childhood days. Ms. Lee's own father was a small town Monroeville, Alabama lawyer, and he is obviously the model for Atticus Finch. Like Scout, Lee was "a rough 'n' tough tomboy," according to childhood friends. Lee's best friend while growing up was young Truman Persons (later writer Truman Capote), who visited next door to her Monroeville home each summer--just as Dill visited his Aunt Rachel. Many of their own frolics were undoubtedly used as a basis for the antics portrayed in To Kill a Mockingbird.
There are no direct quotes spoken by Scout that can be attributed specifically to Harper Lee, and the author continues even today to refuse all interviews about her endearing novel. But it seems likely that the author created Scout from her own recollections of youth, and even if Jean Louise Finch is not a direct clone of Nelle Harper Lee, she is certainly a close relation.
