Architecture at the university was a topic of controversy in its early stages. In 1968, incoming university president Gregory Wolfe commented that the buildings were distressing evidence of Stalinist cubism on campus, although urban renewal chairman Ira Keller found them to be "perfectly lovely." Portland State University's growth for the next couple of decades was restricted under the Oregon University System's 1929 ruling that no public university or college in Oregon could duplicate the programs offered by another, with grandfathered exclusions for the University of Oregon and Oregon State University.
