Charles M. (Charles Matthews) Manly

Born in Staunton, Virginia, in 1876, Charles Matthews Manly was an American engineer whose career was closely tied to the earliest experiments in powered flight. After studying engineering at Cornell University, he was chosen by Samuel Pierpont Langley to help build and refine the Great Aerodrome, one of the most daring American aviation projects of its time.

He made his biggest mark through engine design. Manly played a major role in developing the lightweight, high-power Manly-Balzer radial engine, a remarkable achievement for its era and an important step in the evolution of aircraft engines. He also personally took part in the Aerodrome trials, serving as the pilot in the famous 1903 launch attempts over the Potomac River.

Although Langley's aircraft did not achieve a successful manned flight, Manly's work earned lasting respect among aviation historians and engineers. He later remained active in engineering and is remembered today as one of the skilled, determined figures who helped lay the groundwork for modern flight.
