Thomas Davies (c. 1713 – 1785) was a Scottish bookseller and author. He studied at the University of Edinburgh and was for some 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 close friend and to whom he dedicated his edition of the works of Massinger. He wrote a successful Life of Garrick (1780), which passed through four editions, and Dramatic Miscellanies (three volumes, 1783-4).
He was born about 1713, and was educated at the University of Edinburgh (1728 and 1729). In 1736 he appeared in George Lillo's Fatal Curiosity at the Haymarket, then under Henry Fielding's management. He then tried bookselling, but failed and returned to the stage. On 24 January 1746 he attempted the part of Pierre in Venice Preserved, which was performed for his benefit at Covent Garden. He next became a travelling actor, and married the daughter of an actor at York, named Yarrow.
Davies performed at Edinburgh, where he was accused of monopolising popular parts, and then at Dublin. In 1753 he was engaged with his wife at Drury Lane, with some success as understudies. In 1761 appeared Churchill's Rosciad, in which the line "He mouths a sentence as curs mouth a bone" which, according to Samuel Johnson, drove Davies from the stage. Davies apparently left the stage in 1762, when he again set up as a bookseller at 8 Russell Street, Covent Garden. Here in 1763 he introduced James Boswell (who had been introduced to him by Samuel Derrick) to Johnson.
