In 1870, one of Garfield's best friends and former students, Burke A. Hinsdale, was appointed Hiram's president. Although there were two before him, Hinsdale is considered the college's first permanent president because the others served only briefly. The next president to have a major impact on the college was Ely V. Zollars, who increased enrollment significantly, established a substantial endowment and created a program for the construction of campus buildings. Later presidents who served for at least 10 years were Miner Lee Bates, Kenneth I. Brown, Paul H. Fall, Elmer Jagow, and G. Benjamin Oliver.
