Percival Wren (1885–1941) was a British writer, mostly of adventure fiction, who is remembered best for Beau Geste, a much-filmed book involving the French Foreign Legion in North Africa, and its sequels, Beau Sabreur and Beau Ideal. After graduating with an MA from Oxford, he traveled the world for five years before joining the British Calvary. From there, he went on to join the French Foreign Legion. World events saw him returning to active service during World War I with the India Army in East Africa, after which he settled in London in 1917. He lived out the remainder of his life in England, concentrating on his literary career. He produced almost fifty titles during his lifetime, including The Snake and The Sword, Sinbad the Soldier, The Disappearance of General Jason, and The Uniform of Glory.
