During 1955-56 planning was under way for the Flint Campus. First classes were held in September of 1956 in temporary spaces while the Mott Memorial Building was under construction, a gift from the Charles S. Mott Foundation. This building was owned by the Flint Board of Education but dedicated for use by the University of Michigan. An agreement between the University and the Flint Board of Education concerning the shared use of facilities was formalized in May of 1959.
Expansion of the Flint Campus facilities was not long in arriving. In February of 1965 the firm of Nurmi, Nelson and McKinley Associates was hired as architects for the expansion program. In March of 1970, 17.27 acres were purchased. A gift of Mr. and Mrs. Colman J. Ross was accepted in November of 1971 for a Chancellor's residence, and this was named the Ross House.
