Many people have made this project possible and supported it along the way. I am grateful to those in the History Department of The Australian National University who provided resources and guidance during my doctoral study of Bartholomew: Doug Craig and Anne Curthoys, Bob Barnes, Bill Craven, Stephanie Tarbin, and, above all, John Tillotson, whom I thank for his patient support, encouragement and friendship from the beginning of the project. I thank Alisdair Greig and the staff of the ANU School of Social Studies for my accommodation as a Visiting Fellow from 2003 to 2007. Dr Bruce Moore and the ANU Publication Subsidies Committee have kindly helped to finance production of the book. The scope of my topic has led me to trespass at times into others’ fields and I thank Merridee Bailey, Anke Bernau, Tania Colwell, Julie Hotchin, Val Spear and Janet Hadley Williams for their generosity in reading drafts and sharing insights. Thank you to Kathy Hagon and Pam Kelloway for their constant encouragement. I thank the staff of the Bibliothèque nationale in Paris; the University of London Library, the British Library, the Wellcome History of Medicine Library and the Warburg Institute Library; the Bodleian Library, Balliol College Library and Corpus Christi College, Oxford; Cambridge University Library, and Bristol City Library for all their help. I am grateful to the British Library and to Cambridge University Library for permission to reproduce images from their manuscript collections. ANU E Press have been a pleasure to work with, as has John Owen, whom I thank for his judicious editing. Thanks to Yasmine Musharbash for her assistance with material in German and to Geoff Hinchcliffe for technical help. Particular thanks go to my family, especially Ian.
