George Allen & Unwin in the UK
George Allen and Sons was established in 1871 by George Allen , with the backing of John Ruskin , becoming George Allen and Unwin in 1914 as a result of Stanley Unwin's purchase of a controlling interest. Unwin's son Rayner S. Unwin and nephew Philip helped run the company, which published the works of Bertrand Russell , Arthur Waley , Roald Dahl and Thor Heyerdal . It became well known as J. R. R. Tolkien 's publisher, some time after publishing the popular children's fantasy novel The Hobbit in 1937, and its high fantasy sequel The Lord of the Rings novel in 1954–1955.
Rayner Unwin retired at the end of 1985, and the firm was amalgamated in 1986 with Bell & Hyman to form "Unwin Hyman Limited". Robin Hyman became chief executive of the combined Unwin Hyman. From this time Allen & Unwin was an Australia-based, child company of Unwin Hyman. Rayner Unwin returned for a while as part-time chairman of Unwin Hyman, retiring again at the end of 1988. It was over the objections of largest shareholder Unwin that Hyman sold the firm to HarperCollins .  HarperCollins has since sold Unwin Hyman's academic book list to Routledge .
