They established the company in 1909 to sell aircraft to the U.S. Army Signal Corps.
The Wright Brothers concentrated their efforts on protecting their patent rights rather than on improving their aircraft. Wilbur Wright died in 1912, and in 1915 Orville Wright sold the company, which later merged with the Glenn L. Martin Company to form Wright-Martin.
Many of the papers of the original Wright Company are now in the collection of the Seattle Museum of Flight.
