Anna M. Fitch (1840–1904), born Anna Corry (also spelled Cory), was an American writer who achieved distinction as one of the earliest women in California to write and publish a novel. Over the course of her life, she was known by multiple names due to her marriages, including Schultz (or Shultz) after her first marriage, and eventually Fitch after her second.\n\nFitch published her literary work under various pseudonyms, including Anna Guesner, Anna Kluesner, and Marisa A. Guesner. In addition to her independent writing, she maintained a close intellectual and creative partnership with her second husband, Thomas Fitch, a well-known politician and orator. This relationship was characterized by mutual literary assistance; contemporary accounts suggest that she actively helped him compose his public speeches, while he assisted her in the writing and refinement of her poetry.\n\nThrough her pioneering contributions to the early literary landscape of California and her collaborative work, Fitch remains a notable figure in nineteenth-century American regional literature.
