Dayton Triangles Locker Room

The Dayton Triangles, an amateur football team organized in 1916, consisted of employees from three Dayton factories—DELCO, Dayton Metal Products, and the Domestic Engineering Company—whose downtown industrial triangle gave the team its name. On October 3, 1920, the Dayton Triangles played the first game of the National Football League, defeating the Columbus Panhandles 14-0 at Triangle Park in north Dayton. The team was a charter member of the American Professional Football Association, organized in Canton, Ohio, on September 17, 1920, and the association's name was changed to the National Football League in 1922. This building, built circa 1916 in Triangle Park in Dayton, was one of two locker rooms on the team's home field.
