John J. Pruis (December 13, 1923 – January 15, 2016) was an American academic, best known as being a president of Ball State University as well as having a building dedicated in his name on the campus.
The Ball State University Annual Fund grew from $170,758 to approximately $1.8 million during John J. Pruis' presidency.
The architecture firm responsible for the design of Pruis hall was influenced by a grand piano with its strong curves and angular walls.
Pruis Hall is located directly southeast of Bracken Library, and is used for large gatherings of people.
The building can hold up to 700 people and hosts Friday Night Movies as well as guest lectures, comedians, and other special events.
