Designed as a trainer for the U.S. Army Air Service, the Curtiss JN-4 first flew in 1916. Known popularly as the “Jenny,” the JN-4 taught thousands of Allied pilots to fly during World War I. After the war, surplus Jennys were widely used for “barnstorming”—traveling air shows—and they opened the first scheduled air mail service.The JN-4D featured a 90-horsepower Curtiss OX-5 engine. The Army ordered Curtiss to convert six JN-4Ds for the U.S. Air Mail Service by installing a larger 150-horsepower Hispano-Suiza engine and a mail compartment. These airplanes were redesignated as JN-4Hs.The Smithsonian acquired this Jenny in 1918.
