|Wright Brothers Hill, constructed from 1938 to 1940, commemorates the exceptional achievements of the Wright brothers. The site overlooks the Huffman Prairie Flying Field, a National Historic Landmark where the Wright brothers mastered their flying skills and developed the first practical airplane, the Wright Flyer III.11 Wright Brothers Hill was designed by the acclaimed Olmsted Brothers landscape architecture firm. The memorial was made possible through the efforts of two civic-minded Dayton business leaders, John H. Patterson and Colonel Edward A. Deeds. With the help of the Olmsted firm, Patterson and Deeds brought healthy, pleasant, outdoor environments to the Dayton area. Wright Brothers Hill has attained local and national significance because of its history of public access, its proximity to other historical locations of aviation innovations, and its status as the work of a design firm that has profoundly influenced American landscape architecture.
