Kelly Library was built in 1972 and is named for a respected member of the McKeesport community, Dr. J. Clarence Kelly. Dr. Kelly was born December 27, 1882 on a farm near Slippery Rock, PA. He graduated from Slippery Rock State Normal School in 1904, with a bachelor of science degree. He went on to graduate from the newly founded University of Pittsburgh School of Medicine in 1910. He worked at McKeesport Hospital and Presbyterian Hospital, and was visiting surgeon at Pittsburgh Hospital and Columbia Hospital in Wilkinsburg, until 1917. That year, he began practice of general surgery and gynecology on the staff of McKeesport Hospital. In 1952, 20 business and professional friends donated $4,000.00 to McKeesport Hospital to furnish an operating room in the new wing in his honor. At the time of his death in 1970, he was still a member of the consulting staff.
On Wednesday, October 10, 1979 at 10:30 AM in the Ostermayer Auditorium, campus and university leaders dedicated the library to the memory of Dr. Kelly. The plaque (now displayed inside the main floor entrance) reads, "Whose slender figure cast a giant shadow of compassion and understanding across the community, inspiring others to acts of service and generosity emulating his own benevolences."
