William H. Zimmerman, an inventor and scholar, was hired in 1873 to rebuild the College’s science lab and serve as professor of natural philosophy.  The College principal, William J. Rivers, disagreed with Zimmerman’s “modern” views about geology, anthropology, and the theory of evolution.   Rivers asked the Board to investigate any teaching that might lead students to “skepticism” and in his 1880 commencement address warned against “anti-religious” philosophies.  Two years later the Board asked for Zimmerman’s resignation.
