On September 17, 1917, Curtiss Aeroplane and Motor Company’s Buffalo operations stood at the center of America’s rapidly expanding aviation war effort. The United States had entered World War I only months earlier, on April 6, and military orders were driving Curtiss to enlarge its workforce, facilities, and production capacity. A photograph from that date documents the company’s Buffalo plant manufacturing airplanes amid this extraordinary period of expansion.
Curtiss had moved much of its manufacturing activity and its headquarters to Buffalo in 1916, drawn by the city’s transportation links and industrial capacity. During the war, the company became one of the country’s leading aircraft manufacturers. Its best-known product, the Curtiss JN “Jenny,” served principally as a military training airplane, while the company also manufactured aircraft, engines, and related components for the wartime aviation program.
The scale of expansion was striking. In late July, Curtiss contracted to construct its North Elmwood plant, a complex covering 72 acres and containing 31 acres of floor space under one roof. A contemporary account states that it was completed and put into operation in 90 days, placing its opening after the September 17 photograph. By the end of the war, Curtiss employed approximately 18,000 people in Buffalo and 3,000 more in Hammondsport, producing about 10,000 aircraft during the conflict.
World War I also helped broaden industrial employment opportunities for women, who increasingly moved into manufacturing and office roles that had often been restricted to men before the war. Curtiss’s growth in Buffalo belonged to that wider transformation of the American home front: private industry, government procurement, and a rapidly changing workforce combined to make large-scale aircraft production possible.
Rather than representing a fully matured wartime factory on a single day, this September 17, 1917 image captures a company—and an industry—in motion. Curtiss’s Buffalo expansion illustrates how quickly American aviation manufacturing grew during the war and foreshadowed the much larger aerospace mobilizations of the decades that followed.
