An important aspect of presenting the Walkowitz renderings of Isadora Duncan is found in the preservation and restoration of the drawings themselves. From the inception of the gift in 1993, John Krill, Paper Conservator at Winterthur Museum and Gardens, and the graduate Fellows in the Art Conservation Department, University of Delaware have made yearly selections and treatments of the Duncan drawings as part of their studies in artists' materials and techniques. For example, important discoveries in dating as relevant to the colored construction papers provided insights to the often difficult task of creating an accurate chronology based on Walkowitz's work. Significant information on dating these colored papers was provided by Conservation Fellows Joan Irving and Penley Knipe. In the painstaking process of preserving and restoring these and other Walkowitz works, the Fellows gain valuable experience, while at the same time, the Gallery-held works on paper are stabilized for posterity. These treated works on paper most aptly demonstrate the discipline of art conservation: a unique blend of science and aesthetics.
