The Sperry who designed and built this aircraft was Lawrence Sperry, the son of the Sperry who was famous for developing gyrocompasses. Lawrence Sperry set up an aircraft company completely separate from his father's business. Lawrence Sperry publicized this little aircraft by landing one at the foot of the steps of the Capital Building in Washington DC. Unfortunately, Lawrence Sperry's aircraft enterprises ceased after he was killed when he crashed while attempting to fly one of these Messenger aircraft across the English Channel.

This tiny (17 feet 9 inches long, 20-foot wingspan) seingle-seat biplane was intended to be serve as a flying messenger vehicle, to replace a messenger mounted on a motorcycle. About 50 were built for the Army Air Service shortly after World War I, of which a dozen were experimentally converted into "aerial torpedoes", early versions of what would later be characterized as "flying bombs" or "cruise missiles".
