The Driehaus Museum, established in 2008 in the historic Nickerson Mansion, expanded its footprint in 2022 with the acquisition of the adjacent John B. Murphy Memorial Auditorium. This six-story, French Renaissance-style building was designed by noted Chicago architecture firm Marshall and Fox, and built between 1923 and 1926 for the American College of Surgeons. The Murphy originally served as a center for surgical research, education, and advancement, and to develop programs for the standardization of hospitals. Its two-story limestone exterior features a pair of cast bronze doors produced by Tiffany Studios, with a towering stained-glass window inside the auditorium.
