William Berry, 1st Viscount Camrose

William Ewart Berry, 1st Viscount Camrose DL (23 June 1879 – 15 June 1954), was a British newspaper publisher.

Berry was born in Merthyr Tydfil in Wales, the second of three sons of Mary Ann (Rowe) and John Mathias Berry. Berry started his working life as a journalist and established his own paper, Advertising World, in 1901. Berry made his fortune with the publication of the World War I magazine The War Illustrated, which at its peak had a circulation of 750,000. In partnership with his younger brother, Gomer Berry, 1st Viscount Kemsley (the elder brother was Seymour Berry, 1st Baron Buckland), he purchased The Sunday Times in 1915 and was its editor-in-chief until 1937. In 1919 the pair also purchased the Financial Times.

In 1924 the Berry brothers and Sir Edward Iliffe set up Allied Newspapers and purchased the Daily Dispatch, the Manchester Evening Chronicle, the Sunday Chronicle, the Sunday News, and the Sunday Graphic, as well as a string of other newspapers across the country. In Cardiff they merged four newspapers into the Western Mail. In 1927 they purchased The Daily Telegraph from the 2nd Baron Burnham, with William Berry becoming its editor-in-chief. In 1937 they purchased its rival, The Morning Post.
