We gratefully acknowledge the donors of the generous financial assistance to the costs of research which made this book possible.

We would also like to express our debt to several persons.

Professor Michael Roe was actively consulted throughout the research of the book, and attentively read the entire manuscript. Ian Castles gave us the benefit of his marvellous knowledge of detail and documentary sources, and, as guardian of the Roland Wilson Archives, kindly put these at our disposal.

We also thank Marjorie Harper for participation in a workshop on part of the manuscript, and for granting us access to some documents of which she is custodian; and Peter Karmel and Cristina Marcuzza for presenting to and participating in other workshops on the manuscript.

We also thank Paul Samuelson for his permission to use some correspondence, Craufurd Goodwin for drawing our attention to some interesting Bloomsbury connections, Kaye Fenton for preparing a meticulous and near-exhaustive bibliography of the four at the beginning of our research, and Frank Hytten for his hospitality and memories.

We give our special thanks to Lady Joyce Wilson for providing us, and giving us permission to use, the several photographs of Sir Roland Wilson.

And we thank John Ancher for his assistance with the archives of The Hutchins School, and Rosalind Moad for her assistance with the archives of Wycombe Abbey School.

We also thank the staff of:
