William Percival Crozier (1 August 1879 – 16 April 1944) was a British journalist and editor of the Manchester Guardian from 1932, when he succeeded Ted Scott, who had died in a sailing accident, until his death in 1944.
Crozier was born at Stanhope in County Durham on 1 August 1879, the youngest son of Rev. Richard Crozier, a Methodist minister, and his wife, Elizabeth Hallimond. He was educated at Manchester Grammar School and Trinity College, Oxford, where he gained a first class degree in Classics (1900).
After leaving Oxford he spent a year as a schoolmaster in Knaresborough, before abandoning teaching for journalism, joining first The Times and then the Manchester Guardian in 1903. He made an impression with his critical analysis of the case for tariff reform, and quickly came to the attention of the Guardian's then editor, C. P. Scott, who, recognising Crozier's potential, made him his right-hand man at the paper in charge of news gathering. In 1912 Crozier was made news editor and in 1918 military critic. He also later served as foreign editor. Under Scott, Crozier reorganized the Guardian's foreign news service, increased the use of photographs and maps, encouraged new features and introduced the daily crossword in 1929. He also developed a deep commitment to Zionism and became "the leading advocate in the daily press of a Jewish national home." (Morris)
