Margaret Holben Ellis
Eugene Thaw Professor Emerita of Paper Conservation; Exhibition Conservator, Art Institute of Chicago
M.A. in Art History and Advanced Certificate in Conservation, Institute of Fine Arts, NYU
Although now retired, I am fortunate to enjoy the vibrant Institute community. My tenure with the Institute has been a long one: in 1987 I was appointed the Sherman Fairchild Chair of the Conservation Center, coming from the Metropolitan Museum of Art department of paper conservation. Since then, I taught the conservation treatment of prints and drawings, as well as technical connoisseurship for art historians. In 1998, I was honored to be invited to plan the facilities and programs of the Thaw Conservation Center at the Morgan Library & Museum, where I served as the Center’s first Director until 2017.
I am a Fellow and past President of the American Institute for Conservation (AIC), a Fellow and past Board member of the International Institute for Conservation of Historic and Artistic Works (IIC), and a certified Conservator/Restorer of the Institute of Conservation (ICON). Fellowships include the American Academy in Rome (1994), the Getty Conservation Institute (2015), and the Menil Drawing Institute (2023). At present, I serve as Exhibition Conservator for Willem de Kooning: Drawing (expected 2026) for the Art Institute of Chicago. I am founder of the online resource LEOcode.org, a growing compendium of the papers of Leonardo da Vinci.
I have published and lectured on artists ranging from Raphael, Dürer, and Titian to Pollock, Samaras, Lichtenstein, Dubuffet, and, currently, Willem de Kooning. My research on artists’ materials and techniques is also broad and encompasses Day-Glo colors, Magic Markers, and Crayola crayons.
