The Rankin Science Building was constructed in 1963 at a cost of $890,000. The building provided classrooms and laboratories, as well as offices for the Departments of Chemistry, Physics, Biology, and Geology. It was formally dedicated on October 26, 1963. In 1969, an addition was added at a cost of $2,640,000.
The building was named for James Daniel Rankin. He served as professor of English at the Normal School from 1921-1929 and then served as dean of ASTC until 1955. In June of that year, he was elected president of the college but retired shortly thereafter on September 1, 1955. At the time the building was dedicated, he was President Emeritus of Appalachian State Teachers College.
As of 2021, Rankin Science Building encompasses three buildings: Rankin Science North, South, and West. This complex houses the Departments of Biology, Geography & Planning, and Geological & Environmental Sciences.
