1900s smoked, talked and played chess. Along with Irion Hall, Old Main even served as the university library (in an unofficial capacity) before Memorial Library was built. Mill Theater was acquired by the university in the early 1960s. Before becoming the primary theatrical space for the college, the single story building functioned as the molding mill for the Hammerschmidt lumber operations. (Legend has it that David Payne, Theater Technical Director who died in an accident in 1968, haunts the theater and Scene Shop.) The theater itself is a thrust space with seating for 180. With the donations from alumni, improvements were made in 2010 which included a new lighting system, sound system, ventilation, and stage. The summer of 2012 saw a renovation of the lobby, doubling its size, and included the addition of a new box office, public restrooms and renovated theater seating, due to alumna Meredith Wallenberg Morrison's (1972) donation through The Wollenberg Foundation. A "black box" style theater like those found in many cities and towns, Mill Theater gives students hands-on experience with all aspects of theater operations, including the opportunity to direct as well as have their own original stage plays workshopped and possibly premiered. The Science Center, dedicated in 1966 and renamed the Arthur J. Schaible Science Center in 1994 in honor of an accomplished graduate (1929) and benefactor, houses the Biology, Chemistry & Biochemistry, Psychology, and Physics departments, as well as general classrooms and 120-seat lecture room Illinois Hall. It also houses the Bates Observatory, which has a 14" computer-controlled Schmidt–Cassegrain telescope and is named in honor of benefactors Alben F. Bates, an Elmhurst attorney, and board of trustees member Joy P. Rasin. Renovation was completed on the physics labs in 2014, the two main biology labs were renovated in 2015, and in 2016, two chemistry labs were renovated. Goebel Hall, which opened in 1928 as the university gymnasium, was renovated in 1978 and again in 1989, when it was converted into an administration building and renamed in honor of the university's third president, Peter Goebel. Offices for Academic Affairs, Advising, Student Financial Services, and Registration and Records can be found there. The lower-level houses the Football locker rooms and offices. The Physical Education Center opened in 1983, and was renamed R.A. Faganel Hall in 2000 in honor of graduate Robert A. Faganel(1952). Faganel Hall houses the Kinesiology Department, athletic coaching offices, two basketball courts
