William Hawley Bowlus, born 8 May, 1896, was a designer, engineer and builder of aircraft and recreational vehicles in the 1930s and '40s. Prior to his work on travel trailers, he was the Superintendent of Construction on Charles Lindbergh's aircraft, the Spirit of St. Louis. He also designed and constructed the innovative but unsuccessful XCG-16A experimental military glider ordered by the U.S. Army Air Corps in 1943.
