Today, Dayton is a great sports town for college basketball, minor league baseball, and more, but having a team in one of the major professional leagues does not seem a realistic possibility. But Dayton will always have a special place in the history of the NFL, as it holds the distinction of hosting the very first league game back in 1920. In this presentation, Andrew Walsh will share the history of the Dayton Triangles, from its founding and connections to the University of Dayton (then St. Mary's College) and prominent Dayton industrialists, to the team's later years and what happened to the historic old stadium. Presented by Andrew Walsh on October 21, 2025. Recorded by Miami Valley Communications Council. Andrew Walsh is an author, researcher, and librarian at Sinclair Community College. Andrew’s book Lost Dayton, Ohio, was published by The History Press in 2018. He writes about Dayton history and urban development on his website DaytonVistas.com, records videos on YouTube and social media, and gives presentations and walking tours locally.
