completed in September 1915 in time for the re-opening. The university reopened for the fall 1915 semester with a total enrollment of 143; with about a third of them ministerial students. OBU has been in continual operation in Shawnee since that time. The name of the university was officially changed to "The Oklahoma Baptist University" in 1920. In 1915, Shawnee Hall housed faculty, staff, classrooms, library, an auditorium which doubled as a gymnasium, and the women's dormitory. Shawnee Hall did not house male students, as they were housed in two privately owned off-campus homes, known as "Hill Hall" (located half of a block south of the intersection of Kickapoo and MacArthur streets) and "Douglas Hall" (located on south University street where Bailey Business Center now stands). Shawnee Hall did not provide enough space for women's housing, therefore, in 1916 ground was broken on a new dormitory for women. The new residential unit was opened in 1917 and named Montgomery Hall, in honor of Dr. and Mrs. D.M. Montgomery, who provided significant financial support for the project. Montgomery Hall served as a dormitory, the fine arts center, the student center, and the location for administrative services. The original Montgomery Hall was located between Shawnee Hall and WMU Memorial Dormitory on the campus oval. The building was removed in 1989 due to structural concerns and a new Montgomery Hall was located on south University street west of the Bailey Business Center. From 1919 to 1928, campus facilities consisted of three buildings, Shawnee Hall, Montgomery Hall, and the combination men's dormitory and gymnasium. In the mid 1920s under the leadership of Berta K. Spooner; Executive Secretary-Treasurer of the Oklahoma Women's Missionary Union, Baptist women of Oklahoma recognized the need for a new dormitory for women on Oklahoma Baptist University's campus. After a fundraising effort to procure sufficient financial support for the new dormitory, groundbreaking occurred in 1927 for the new facility. When WMU Memorial Dormitory opened in 1928, the building housed rooms for 200 female students, the university dining hall, parlors, assembly rooms, a recreation room, an infirmary, and a swimming pool. Due to the challenges of "The Great Depression" in the late 1920s to the 1930s, it would be another decade before another building was constructed on campus. Oklahoma Baptist University served as an army aviation training site from February 1943 through the summer of 1944, hosting the 91st College Training Detachment.
