Professional programs during the interwar period were limited to just theology and nursing. By the 1940s the McMaster administration was under pressure to modernize and expand the university's programs. During the Second World War and post-war periods the demand for technological expertise, particularly in the sciences, increased. This problem placed a strain on the finances of what was still a denominational Baptist institution. In particular, the institution could no longer secure sufficient funds from denominational sources alone to sustain science research. Since denominational institutions could not receive public funds, the Baptist Convention of Ontario and Quebec decided to reorganize the university, creating two federated colleges. The arts and divinity programs were reconstituted as University College and science was reorganized under the newly incorporated Hamilton College as a separate division capable of receiving provincial grants. Hamilton College was incorporated in 1948 by letters patent under "The Companies Act", although it remained only affiliated with the university. The university traditionally focused on undergraduate studies, and did not offer a PhD program until 1949.
