The Seiberling Mansion is a historic house located at Kokomo, Indiana, United States. In 1887, Monroe Seiberling of Akron, Ohio, traveled to Kokomo to open the Kokomo Strawboard Company, which would make shoe boxes out of straw and employ seventy-five people. Within six months, Seiberling, uncle of Goodyear Tire and Rubber Company founder Frank Seiberling, sold the Kokomo Strawboard Company and opened the Diamond Plate Glass Company.
