During World War I, Curtiss JN-4 airplanes were built and tested in Waukegan. Also known as "Jenny" by Americans for the JN designation in the name, the biplane was probably North America's most famous WW I plane.
The Jenny was built by the Curtiss Aeroplane Company of Hammondsport, New York, later the Curtiss Aeroplane and Motor Company. Parts for the Jenny were assembled at a Curtiss plant on Market Street in Waukegan, and some metal parts were made at Fansteel in North Chicago.
The Curtiss JN-4 was used to train pilots, but each one needed to be test flown first. Curtiss had its own test pilots, and the Army Signal Corps also had pilots test the planes before they were accepted by the U.S. Army. The test field was on the north side of Waukegan in today's Lyons Woods Forest Preserve on Sheridan Road.

The test field's runway was a farm field, rolled by rollers to smooth the ground as much as possible. The planes would fly to other airfields in Wisconsin, Chicago, and Rantoul.
The twin-seater biplane's maneuverability made it ideal to train pilots. Its top speed was 75 mph, and its service ceiling was 6,500 feet. The JN-4B models were built in Waukegan and powered by an OX-2 piston engine; 76 were sold to the U.S. Army, and 9 to the U.S. Navy.
Civilians took flights in the "Jenny" at the Curtis Flying Field with an official tester for the Curtiss Company. Unfortunately, in October 1919, one death occurred after a flight when the passenger, Hazel Nolan of Waukegan, leaned too close to the propeller.

On July 3, 1920, the Curtiss JN-4 was featured in a parade in Waukegan. During World War I, the "Jenny" was used to entice the purchase of Liberty Bonds to pay off the war debt.
