Diane Cole Ahl,
Arthur J. '55
and Barbara S. Rothkopf
Professor of Art History,
is editor of The Cambridge Companion to Masaccio
(Cambridge University Press, 2002), essays on the influential Florentine painter of the early Renaissance. She also contributed an essay, "Masaccio in the Brancacci Chapel."

Ahl is the author of Benozzo Gozzoli, which shared the Otto Gründler Prize for Best Book in Medieval Studies, awarded at the International Congress on Medieval Studies in 1998; editor of Leonardo da Vinci's Sforza Monument Horse: The Art and the Engineering; and coeditor of Confraternities and the Visual Arts in Renaissance Italy: Ritual, Spectacle, Image. She is authoring a major work on 15th-century painting for Yale University Press and a book on Fra Angelico for Phaidon Press.

Ahl holds a Ph.D. from University of Virginia and B.A. from Sarah Lawrence College. A faculty member since 1977, she has received 13 grants and awards for teaching and scholarship. She calls the contributions of EXCEL Scholars Amy Dorfman '01, Natalia Swiderska '03, and Christine Terzella '03 to the Masaccio book "invaluable" and says her work on projects like the Cambridge Companion has a great impact on her classroom instruction. "It suffuses everything that I teach," she says. "When I edit a book, I become a better teacher of writing. In editing or writing a book, I do research, and what I learn is imparted to my students."
