Samuel Pierpont Langley (1834-1906).

Langley was an American astronomer, physicist, inventor, and aviation pioneer. From 1887 to 1903, he experimented with rubber-band-powered models and larger unmanned aerodromes. In 1903, he successfully flew the unmanned Aerodrome A, 3,300 feet at 30 mph.

His attempts at human-crewed flight were unsuccessful, but his work advanced his understanding of aerodynamics and aviation concepts.
