The Arthur Vining Davis Foundations has contributed $150,000 toward the construction of a new wing at the Colby Museum of Art in response to a $1-million two-for-one challenge from an anonymous donor. The Florida-based Foundations, which in 1991 awarded Colby $100,000 toward the renovation of the Bixler Art and Music Library, ties their gifts to specific projects deemed important by the recipient's leaders, according to Assistant Vice President of Development and Alumni Relations Linda Goldstein. "The Foundations' proposals are rigorous, demanding much data to confirm the quality of the institution and its programs. Once they are convinced of the excellence of a school and its leadership, they will then consider requests based on the president's priority," she said. The 9,700-square-foot wing will house exhibitions featuring works from the museum's permanent collection. In addition to paying for construction, the $3-million fund-raising project includes money for support of student assistants, traveling exhibitions and conservation, and endowment to provide a full-time security guard.
