Guy Chapman was born in London in 1889. Educated at Oxford University he became a lawyer in 1914. Later that year, on the outbreak of the First World War, Chapman joined the Royal Fusiliers as a junior officer and arrived on the Western Front in August 1915.
After surviving the Battle of Arras in 1917, Chapman was badly affected by a mustard-gas attack. After treatment he returned to the Western Front and was still there when the Armistice was signed in 1918.
Chapman became a university lecturer and eventually became Professor of Modern History at the University of Leeds. He published several books including an account of his wartime experiences, A Passionate Prodigality (1933). He also edited an important collection of prose from the war, Vain Glory (1937). After his death in 1972, his wife, Storm Jameson, edited A Kind of Survivor (1975), a selection of Chapman's autobiographical writings.
