Frank Baum, author of Wizard of Oz books was highly influenced by Alice from Alice in wonderland.

Although Baum found the plot of Carroll's novel to be incoherent, he identified the book's source of popularity as Alice herself—a child with whom younger readers could identify, and this influenced Baum's choice of Dorothy as his protagonist.
