The J-1 was designed by Charles Day, who was also responsible for the Curtiss Jenny.
During WWi the J-1 was ordered to supplement the Jenny in filling the Air Service’s growing need for training aircraft.
The J-1 was limited by it’s early powerplant, the Hall-Scott A-7.
The Armistice of 1918 resulted in the cancellation of over 2,700 J-1s. When the J-1 was withdrawn from military use, several companies bought them and re-engined them to improve reliability and performance.
