Salk Hall 1920s. Also contained in Salk Hall is the Elmer H. Grimm Sr. Pharmacy Museum, which opened in the fall of 1996. Located on the fourth floor, the museum holds pharmacy memorabilia such as drug products, equipment, and sundry products dating back to the early 20th century. Among the museum's possessions are two hand-carved finials, which were often found over the door or partitions that separated the main part of the pharmacy from the back room where pharmacists did most of their work, an old-fashioned powder mill, and a konseal machine.
