I owe a particular debt of gratitude to Donna Sammis of the Frank Melville Library of the State University of New York at Stony Brook. I would also like to thank the staffs of the Butler Library of Columbia University and the Cabinet des Estampes of the Bibliothèque Nationale de Paris.
My thanks go to Paula Deitz for publishing a version of chapter 4 in the Autumn 2012 issue of The Hudson Review.
Among the many friends whose conversation and encouragement buoyed me, I must make special mention of Ruth Kozodoy, who perused the manuscript with pencil in hand at various stages of the writing.
My thanks go as well to Georges Borchardt, the kindest and most helpful of agents.
I am indebted above all to Victoria Wilson of Knopf, whose devotion and care made this work possible.
