This science building was originally to be built in Georgian-style architecture, but this was abandoned due to cost and expandability options. Though built in 1971, the building was nameless until 1982 when it was named in honor of the retiring president, Dr. Hudson T. Armerding. As a student at Wheaton he took history courses under Dr. Edman and later earned a Ph.D. in Asian History and Institutions. Dr. Armerding served as acting president of Gordon College before returning to Wheaton to serve in the history department in 1960. In 1963 he became Provost and served in that office until he became President in 1965. The Perry Mastodon exhibit was dedicated in January 1975.
