E. P. S. (Evelyn Prestwood Seymour) Allen

E. P. S. Allen was the pen name of Evelyn Prestwood Seymour Allen (1885–1972), a British-born writer closely associated with Canada. Records and library listings identify him as the author of The 116th Battalion in France, a history of a Canadian Expeditionary Force unit in the First World War.

Military records describe him as a captain and adjutant with the 116th Battalion, and one source also lists his civilian occupation as actuary. He was born in London on December 14, 1885, later lived in Canada, and died in Toronto in 1972.

Allen is best remembered for writing from direct knowledge of the battalion he served with. That firsthand connection gives his work a steady, documentary feel that can be especially appealing to listeners interested in military history, regimental life, and personal perspectives on World War I.
