In 1914, Frederick W. Hinitt was elected president. His tenure was dominated by the United States' entry into World War I, with an enrollment drop of 50%.
William E. Slemmons, a college trustee and adjunct professor, succeeded Hinitt and served as interim president from May 1918 to June 1919. After the war ended in 1919, Samuel Charles Black took over and helped to stabilize the enrollment. While on a honeymoon tour of national parks, Black became ill and died.
His successor, Simon Strousse Baker, was well liked by the college's trustees and by "many a townsman," but the student body felt that Baker was "autocratic" and held an "unfriendly attitude toward the student body as individuals."Baker defended himself, saying that the perceived ill-will towards students was unintentional and a misunderstanding. Nonetheless, the student body held a strike and general walkout in 1931, prompting Baker to resign.
