To meet Muncie’s higher education needs, the Ball Brothers gave land, money, and the building here to the state in 1918. Their gift became the Indiana State Normal School Eastern Division and was renamed Ball Teachers College in their honor in 1922. During the 1930s and after WWII, the college experienced major growth in enrollment, facilities, and programs. After achieving university status in 1965, Ball State University expanded with the addition of new educational offerings such as the College of Architecture and Planning. In the 1970s, BSU became a national leader in disability education and campus accessibility. Innovation continued into the 2000s, as evidenced by the pioneering geothermal energy system.
