Did I say it was scandalous? I don't remember saying that. I know Jo March was thought to stand in for the author, Louisa May Alcott, and there were several things about Alcott that were scandalous at the time, according to this article.
I haven't read the article yet but I've long assumed LMA was a lesbian. Jo March is very much based on her (as the sisters and parents are based on her own sisters and parents). So that's why Jo March doesn't marry
Christian Bale Laurie, her neighbor close friend and presumed love interest. And apparently her publishers made LMA have Jo marry someone, so she picked a not very sexy professor. (Although in the Greta Gerwig version, the guy Jo marries is actually attractive.)
I visited LMA's childhood home some years ago. Very interesting. Among other things, she pounded out
Little Women in about a month, at the request of an editor who thought she should write a book for women. Then she wrote a sequel.
Her desk was a fold-out desktop about the size of a desktop in grade school. In LW, the character of her sister Amy is artistic. In their house, "Amy's" drawings are all over some of the walls.
