John Rudolph Freuler (1872-1958), a Wisconsin native, was one of the founders of the American Film Manufacturing Company, which later became the American Film Company (popularly known as the Flying A Studio), and subsequently, the Mutual Film Corporation. Based in Chicago, the company was a major production studio in the late 1910s and early 1920s. Chicago was the location of film production as well as business and administrative functions until 1913, when production moved to the company's new facilities in Santa Barbara, California, and administrative and distribution offices remained in Chicago.
