Sir Arthur Thomas Quiller-Couch, (21 November 1863 – 12 May 1944) was a Cornish writer who published using the pseudonym Q. Although a prolific novelist, he is remembered mainly for the monumental publication The Oxford Book Of English Verse 1250–1900 (later extended to 1918) and for his literary criticism. He influenced many who never met him, including American writer Helene Hanff, author of 84, Charing Cross Road and its sequel, Q's Legacy. His Oxford Book of English Verse was a favourite of John Mortimer's fictional character Horace Rumpole.
