Margaret Holben Ellis is the Eugene Thaw Professor Emerita of Paper Conservation at the Institute of Fine Arts, New York University, where she teaches the conservation treatment of prints and drawings and technical connoisseurship for art historians. She has published and lectured on artists ranging from Raphael, Dürer, and Titian to Pollock, Samaras, Lichtenstein, and Dubuffet. Her research on artists’ materials and techniques is also broad, encompassing Day-Glo colors, Magic Markers, and Crayola crayons.

C. Richard Johnson, Jr. received the first PhD minor in Art History granted by Stanford University along with a PhD in Electrical Engineering in 1977. He is currently the Geoffrey S. M. Hedrick Senior Professor of Engineering at Cornell University. He is also a Visiting Research Professor at the Conservation Center of the Institute of Fine Arts at New York University, Senior Research Advisor to the Frick Art Reference Library, and a Scientific Researcher at the Rijksmuseum. His research focus for the last 15 years has been matching manufactured patterns in art supports, primarily the canvases of paintings by van Gogh and Vermeer and the laid papers of Rembrandt’s prints and Leonardo’s codices.
