A French naval officer who turned his years at sea into vivid fiction, he wrote adventure-filled stories shaped by real maritime life. His career was cut short in World War I, when he died near Verdun in 1916.

by Olivier Diraison-Seylor
Born Eugène Jules Olivier Diraison on July 31, 1873, in Plouescat, Brittany, he became both a French naval officer and a writer. He published under the name Olivier Seylor, drawing heavily on his experience as a sailor, especially his time based in Toulon.
His first novel, Les Maritimes, appeared in 1901 and was noted for its naval setting. He went on to write more fiction, often linked to sea life and adventure, building a body of work that reflects firsthand knowledge of the French Navy.
He later used the name Olivier Diraison-Seylor and died on June 17, 1916, near Verdun, officially recognized as having died for France during World War I. Because reliable portrait images were not clearly available from the sources I could confirm, no profile image is included here.
