original College of Liberal Arts (founded in 1844). To address the need for new departments and specialized instruction, the administration improved the facilities and courses to make them on par with OWU's new academic position. University Hall, Slocum Library, extensions to the Monnett campus, and athletic facilities were all constructed during that period. Between 1891 and 1895, Ohio Wesleyan specialized the curriculum by establishing departments for physics, zoology, geology, speech, history, French, English, and economics. This specialization encouraged undergraduates to continue studies at graduate level, allowed professional preparation for the Doctor of Philosophy degree, and promoted exchange study in Europe. Two professional schools for law and medicine were formed in 1896. In 1905, the Board of Trustees decided to keep Ohio Wesleyan a college, despite the expansion of the curriculum and campus and the word "university" in the institution's name. The Bachelor of Science degree was abolished, which left only the Bachelor of Arts. Two students were selected as Rhodes Scholars in 1905 and 1909. Edwards Gymnasium was built in 1906. In 1907, the United Societies of Phi Beta Kappa, the oldest undergraduate honor society in the United States, installed the "Eta of Ohio" ΦΒΚ chapter on campus. In 1909, the school added Sanborn Hall, housing the Music Department. In the 1920s, academic requirements for the bachelor's degree were reduced, and Latin and mathematics were no longer emphasized. During the presidency of John W. Hoffman (1916–1928), the academy and School of Business were closed; the academy had started in 1842 as a preparatory school, and throughout its seventy-five years frequently outnumbered the college in enrollment. Also in the 1920s, the chapel service was dropped and sororities were formed. Ohio Wesleyan also increased the number of buildings on campus, including Selby Stadium, Austin Manor, and Perkins Observatory; another building, Stuyvesant Hall, was in planning; and Edgar Hall was opened. Curriculum changes (1930–1984) During the Great Depression, both enrollment and alumni donations shrank. While the faculty size remained stable, lack of tuition and alumni revenues precipitated financial problems which threatened the college's survival in the administrations of Edmund D. Soper (1928–1938), Acting President Edward Loranus Rice (1938–1939), and Herbert John Burgstahler (1939–1949). The administration adjusted the curriculum during the early 1930s to address these problems. Greek and Latin declined, while business administration and economics thrived and the highest enrollments were in the social sciences, English, pre-medicine, and history. The registrar reported that,
