Examples of authors writing characters like them in their works?

-I'm writing an essay on how F. Scott Fitzgerald paralleled himself in Jay Gatsby and would like to mention other examples of authors writing themselves into literature. Please help, thank you! :)Charles Dickens in David Copperfield

Hermann Hesse in Steppenwolf

D H Lawrence in The Rainbow

Henry James in The Portrait of a Lady

E M Forster in Howards End



Those are off the top of my head - will have a bigger think though :)
