This book's genesis was an invitation from Lee Ripley Greenfield. Although that original project foundered, I am grateful to her for the invitation and even more grateful to Cass Canfield Jr. for following it up and believing my book worthy of the distinguished imprint he edits. I am also thankful to my students at Reed College, who responded critically to virtually all of the ideas in this book, generated some of them themselves, and tolerated their role as guinea pigs when I tested its organization and contents.
Thanks to all of the museums, libraries, and photo archives that provided photographs, especially those that reduced or waived their fees and therefore made this book possible. The Stillman Drake Fund of Reed College provided crucial support for the photographs and for a research assistant. That assistant, Anne Oravetz, was more talented and thorough than I could have hoped.
Kim Clausing, Abby McGehee Poust, and Isuru Senagama provided invaluable assistance at moments of crisis. Kathy Delfosse was an exemplary copy editor; she saved me from many errors and improved the text in all sorts of ways.
My family, Debby, Joseph, and Abby, not only gave me time to write this book, they often showed more enthusiasm for the process of writing it than did I. I first encountered many of the works of art I discuss in the company of my parents, Ruth and Bill Diebold. Without their love, support, encouragement, and example this book would never have come into being.
