The Curtiss JN-4 "Jenny" was one of a series of "JN" biplanes built by the Curtiss Aeroplane Company of Hammondsport, New York, later the Curtiss Aeroplane and Motor Company. Although the Curtiss JN series (the common nickname was derived from "JN") was originally produced as a training aircraft for the U.S. Army, the "Jenny" continued post-World War I as a civil aircraft as it became the "backbone of American post-war [civil] aviation." Thousands of surplus Jennys were sold at bargain prices to private owners in the years after the War and became central to the barnstorming era that helped awaken America to civil aviation through much of the 1920s.
