Stearman Aircraft Corporation was an aircraft manufacturer in Wichita, Kansas. Although the company designed a range of other aircraft, it is most known for producing the Model 75, which is commonly known simply as the "Stearman" or "Boeing Stearman".
Lloyd Stearman established the Stearman Aircraft Corporation in 1927. Initially, the company was founded as Stearman Aircraft Corporation in October 1926 at Venice, California, where four C1 and C2 biplanes were built before production halted for financial reasons. On 27 September 1927 a new Stearman Aircraft Corporation was founded. The factory was then established in Wichita, Kansas with financing of Walter Innes where the new model Stearman C3 and Stearman 4 Speedmail were constructed. Two years later, he sold it to the United Aircraft and Transport Corporation.
In September 1934, anti-trust legislation forced United to separate its airline and aircraft manufacturing operations. At this time, Boeing, which had been part of United Aircraft and Transport Corporation, became a separate business once again, and Stearman was made a subsidiary of it. Stearman officially ceased to operate as a brand then, but about the same time the Stearman plant created its most successful and enduring product, the Model 75 "Kaydet". The Kaydet would become the primary trainer aircraft for the United States military during World War II.
