Ralph Marlow

Ralph Marlow is a little-known adventure writer whose surviving reputation rests mainly on the Big Five Motorcycle Boys series. Reliable catalog and library sources confirm his name on works including The Big Five Motorcycle Boys in Tennessee Wilds and The Big Five Motorcycle Boys on the Battle Line; Or, With the Allies in France.

The books place groups of resourceful boys in energetic, serial-style adventures, with motorcycles, outdoor action, and, in some volumes, World War I settings. From the evidence available in Project Gutenberg and library listings, his work fits comfortably with the popular juvenile series fiction of the 1910s.

Very little biographical information about Marlow himself could be confirmed from dependable sources during this search, so his personal life remains obscure. What can be said with confidence is that his books have endured through reprints, library catalogs, and public-domain editions, which have kept his brisk, old-fashioned adventures available to modern readers.
