All chapters active prior to World War II succeeded in resuming operation after the war. The two in Colorado, however, were lost in 1948 and 1956. One new chapter was installed in 1949, but after a few years became weak and was asked for its charter in 1961. Many felt the Commons Club movement lost its relevance and withered in the more liberal climate of student life after World War II. With the withdrawal in 1963 of the Cincinnati Chapter, which had long been active in the Association, the remaining chapters at Denison and Adrian felt it futile to maintain a national organization with just two chapters. Accordingly, at a Special Convention held at Adrian April 4, 1964, the delegates voted unanimously to suspend national operation as of June 15. By 1964 only the founding chapter at Denison University remained, and in 1969 the American Association of Commons Clubs became an organization of only alumni while the active chapter became a member of Delta Chi national fraternity. At the time of the suspension of the Association, the national officers then current were designated as a permanent Executive Committee to act in the interests of the Association in all matters regarding protection and use of insignia, maintenance of records, disposition of assets, and other matters. These officers included the following: Allan M. Dewey (Denison '37), President; Edward G. Voss (Denison '50), General Secretary; R.A. Wiley (Adrian '50) Treasurer; and John N. Miller (Denison '54), Editor. A complete file of Association Convention proceedings, bulletins, handbooks, mimeographed documents, and publications, including The American Commoner, is deposited in the archives of the William Howard Doane Library at Denison.
