Wimmer Hall was designed by Charles Aldrich of Minneapolis and was constructed in 1901. Like many of the older buildings on campus, Wimmer Hall had a previous life. It was designed and constructed to serve as the library for Saint John's University and served that purpose until the construction of Alcuin Library in 1966. During its earliest days, its top floor also housed one of the first photographic studios in Minnesota along with a rather significant natural history museum.
Today, Wimmer Hall houses administrative computing on the ground floor, the University business offices on second floor, and Minnesota Public Radio (MPR) on the third floor.
Minnesota Public Radio is one of the nation's premier public radio stations producing programming for radio, internet, and face-to-face audiences.
