Thomas S. Baldwin (1854-1923) was an early American airship and aeroplane designer/builder.  He began flying balloons in 1875 and by 1900 was designing and building dirigible airships, including the first such craft purchased by the U.S. Army.  From 1910 to 1913 he built and flew heavier-than-air aeroplanes, and then returned to airships until his death in 1923.

Baldwin Red Devil

The Red Devil aircraft built by Baldwin were innovative in being framed in steel tube rather than the wood which was conventional at the time.  One Red Devil survives, in the collection of the National Air & Space Museum.
