Acknowledgments

I have been blessed with a wonderful family and friends, and although they may not have contributed directly to this book, it would have been impossible to write it without having them in my life. Thanks to my colleagues at Lafayette College and to my colleagues and collaborators elsewhere for your kindness and support. I am grateful to Lafayette College for providing material support and a sabbatical leave to work on the book. In particular, I would like to thank the staff at the Lafayette College Skillman Library, who were generous with advice and amazing at procuring needed materials. Diane Shaw, the Director of Special Collections and College Archives, was very supportive and provided a photograph of James McKeen Cattell for the book. The staff at the Cummings Center for the History of Psychology at the University of Akron and at the Carnegie-Mellon University Archives were helpful in locating information and photographs. In addition, I am also grateful to the following archivists for their assistance in locating photographs: Fred Burwell at Beloit College, Leah Loscutoff at the Stevens Institute of Technology, and Anna Towlson at the London School of Economics.

I would like to thank Dave Repetto, my editor at Cambridge University Press, for his patience and faith that the book would actually be completed. Thanks also to content manager Bronte Rawlings, project manager Revathi Thirunavukkarasu, copy editor Karin Kipp, Robert Swanson for the indexes, and everyone at Cambridge Press who worked on the book. I am grateful to a group of anonymous reviewers for their time and thoughtful comments. And special thanks to my wife Bianca Falbo, Associate Professor of English and Director of the College Writing Program at Lafayette College, who helped wrestle my awkward prose into something resembling grammatical English. This book is dedicated to her.
