"Acton Bell" is the pen name used by the English author and poet Anne Brontë. She adopted this pseudonym to publish her works alongside her sisters, Charlotte Brontë and Emily Brontë, who also used male pseudonyms. The use of male names allowed the sisters to navigate the literary world of the 19th century, which was often biased against female authors. Under the name Acton Bell, Anne Brontë published her novels, including "Agnes Grey" and "The Tenant of Wildfell Hall." These works explore themes of social criticism, women's independence, and moral integrity, showcasing her unique voice and perspective in literature.
