Ernest "Ernie" C. Hall, born near Warren, Ohio in 1890, was a pioneer of early flight widely recognized for his long career in aviation. A friend of the Wright brothers, he built his first powered airplane in 1909 and flew it in 1911. He began his career as a civilian flight instructor in 1913 and opened a flying school in Pennsylvania in 1915. During World War I, he transferred to Call Field in Wichita Falls, Texas, where he trained over 500 military pilots for combat. In 1922, he relocated his flight school to Warren, Ohio, where he taught until his death in 1972. His 1911 monoplanes have been displayed at the Smithsonian's National Air and Space Museum in Washington D.C. and at the National Museum of U.S. Air Force in Dayton, Ohio.
