Martin A. Bansbach

Senior Manager for Installation and Matting

Martin Bansbach’s primary task is the housing of all works from the seventeen curatorial collections that come through Paper Conservation including works on paper, parchment, and papyrus. Most housing consists of cutting acid-free rag-board mats to allow for safer handling and storage of exhibition and loan objects. Martin also frames and unframes works of art that are fragile or problematic, such as pastels, and constructs custom storage boxes and exhibition book cradles. Martin’s position requires a substantial and satisfying amount of interdepartmental interface, as well as cross-disciplinary collaboration.
