George A. Spratt

Life & Legacy

George Alexander Spratt (November 1, 1870 – November 24, 1934) was an American inventor and pioneer in aviation design. In collaboration with the Wright brothers, Spratt demonstrated the cable-stayed triangle control frame for use in mass-shifting the pilot and pilot holding to control the attitude of a lifting wing for any type of aircraft that could benefit from such arrangement. This arrangement ended up being the sub-assembly most used in hang gliders, powered hang gliders, trikes, and ultralights.
