For its first six decades, the AAU functioned as a club for the presidents and deans of elite research universities to informally discuss educational matters, and its day-to-day operations were managed by an executive secretary. In the 1970s, the AAU shifted to a role of active advocacy on behalf of its members' interests; dues were raised, more staff members were hired, and its chief executive was given the title of president and the duty of becoming far more publicly visible than his predecessors.
