The son of a Provost of Queen's College, Oxford, Gerard Langbaine the younger was apprenticed to a bookseller in St. Paul's churchyard before attending University College Oxford, where he later held several positions. Langbaine regarded John Dryden as responsible for the spurious title page ("Plagiaries of the English Stage") appended to his New Catalogue of English Plays (1688) and attempted to exact revenge in Account of the English Dramatick Poets (1691). The antiquary Thomas Hearne esteemed Langbaine as "a very great scholar, and a great judge of our English history and antiquities" Reliquae Hearniae, ed. Bliss (1869) 3:28.
