Through the 1950s increased funding advanced the place of sciences within the institution. In 1950, the university had completed the construction of three academic buildings for the sciences, all designed by local architect William Russell Souter. Public funding was eventually necessary to ensure the humanities and social sciences were given an equal place. Thus, in 1957 the university reorganized once again under "The McMaster University Act, 1957", dissolving the two colleges. Its property was vested to McMaster and the university became a nondenominational institution eligible for public funding. The historic Baptist connection was continued through McMaster Divinity College, a separately chartered affiliated college of the university. Also in 1957, PhD programs were consolidated in a new Faculty of Graduate Studies. Construction of the McMaster Nuclear Reactor also began in 1957, and was the first university-based research reactor in the Commonwealth when it began operating in 1959.
