Cynthia Kracauer, managing director of the Center for Architecture since 2006, has left the organization. The person most responsible for shepherding the successful Archtober program has—according to a spokesperson—decided to leave and “pursue different options.” Kate Mullen, who works in the AIA’s exhibition department, will now be the Archtober lead. The new Executive Director of the AIA New York Chapter Benjamin Prosky will assume, at least temporarily, some of Kracauer’s responsibilities.
