The Amalgamated Press (AP) was a British newspaper and magazine publishing company founded by journalist and entrepreneur Alfred Harmsworth (1865–1922) in 1901, gathering his many publishing ventures together under one banner. At one point the largest publishing company in the world, AP employed writers such as Arthur Mee, John Alexander Hammerton, Edwy Searles Brooks, and Charles Hamilton. Its subsidiary, the Educational Book Company, published The Harmsworth Self-Educator, The Children's Encyclopædia, and Harmsworth's Universal Encyclopaedia. The company's newspapers included the Daily Mail, the Daily Mirror, The Evening News, The Observer, and The Times. At its height, AP published over 70 magazines and operated three large printing works and paper mills in South London.
