William Harrison Ainsworth (4 February 1805 – 3 January 1882) was an English historical novelist born in Manchester. He trained as a lawyer, but the legal profession held no attraction for him. While completing his legal studies in London he met the publisher John Ebers, at that time manager of the King's Theatre, Haymarket. Ebers introduced Ainsworth to literary and dramatic circles, and to his daughter, who became Ainsworth's wife.Ainsworth briefly tried the publishing business, but soon gave it up and devoted himself to journalism and literature. His first success as a writer came with Rookwood in 1834, which features Dick Turpin as its leading character. A stream of 39 novels followed, the last of which appeared in 1881. Ainsworth died in Reigate on 3 January 1882.
