George Alexander Spratt
George A. Spratt (1870-1934): Historic farm where Spratt performed aeronautical experiments that aided Wilbur and Orville Wright in their invention of the airplane. His knowledge helped diagnose an issue with the Wright's 1901 glider. Spratt gave the Wright Brothers his idea of simultaneously measuring the lift and drift forces of a surface which helped them determine the 1903 Wright Flyer's wing shape. The Wrights visited here in December of 1906.
