The Jackling Gymnasium opened in 1915 and was named after Daniel C. Jackling, a successful alumnus who previously gave $1500 to improve the athletic field that was also later named after him.[1] The Jackling Gym was a two-story building; the first floor had a 20-by-60-foot (6.1 by 18.3 m) swimming pool and lockers, while the second floor had a 70-by-90-foot (21 by 27 m) gymnasium.[48] A gallery above the gym had seats to watch basketball games and a running track.[48] After the end of World War II, the gym also housed about two dozen student-athletes in rooms around the pool and basketball court.[48] These students became known as the "Jackling Jocks" and were housed in the building over a period of 15 years.[48] In August 1965, the gymnasium was to be destroyed due to safety concerns.[57] The Jackling Gymnasium was the first building on campus to be demolished.[57] The Curtis Laws Wilson Library was built on the Jackling Gymnasium's former site.[57] The Gale Bulman Building was built in 1969 as a replacement for the Jackling Gymnasium.[48] Built in 1885, the Old Chemistry Building was the second building on campus after the Rolla Building.[115] The Old Chemistry Building burned to the ground in 1969.[116]
