Writing as Jeffery E. Jeffery, Jeffery Eardley Marston was born in 1887 and later became known as both an author and a translator. Sources tied to his books identify him under that pen name, and library records connect him with works including Servants of the Guns, The Burden, and a translation of Elie Faure's Napoleon.
A bookseller's description of Servants of the Guns identifies him as a regular gunner officer who was wounded in August 1914, received the DSO and MC in 1917, and rose to the rank of major. That background helps explain the authority behind his best-known writing on the First World War.
The available sources are thin on personal detail, but they consistently point to a career that blended military service with literary work. I couldn't confirm a reliable portrait image from the sources I found, so none is included here.
