(c. 1712 – 1785) was a Scottish bookseller and author. He studied at the University of Edinburgh and was for several years on the Stage; but having been ridiculed by Churchill in The Rosciad
he gave up acting and opened a bookshop in Covent Garden. It was here that in 1763 he introduced Boswell to Dr. Johnson, who was his intimate friend and to whom he dedicated his edition of the works of Massinger. He wrote a Life of Garrick
(1780), which soon passed through four editions and brought him considerable money and repute, and Dramatic Miscellanies
(three volumes, 1783-4).
