Edward E. Porterfield (-1948) founded the American Eagle Aircraft Corp. in Kansas City, Kansas, in 1925. The company produced a simple, three-seat training and utility biplane powered initially by a war-surplus Curtiss OX-5 engine, one of many such designs that proliferated around the U.S. in the late 1920s. The plane was produced until 1931, when the depression killed American Eagle. The company was revived as part of the Lincoln-Page Aircraft Co. of Lincoln, Nebraska, and resumed production of the biplane until 1932. It also produced a high-wing two-seat monoplane in 1931-32.
Porterfield went on to found a second aircraft company, the Porterfield Aircraft Corp., which built a new, side-by-side high-wing monoplane. Though well liked and favored by antique enthusiasts today, the Porterfield enjoyed only moderate success, and unlike several other light aircraft manufacturers, Porterfield did not secure a military contract for liaison aircraft in World War II. This proved fatal to the company.
