MANY people have helped me in the preparation of this book, by sharing their recollections of Lord Beveridge, by the loan of private correspondence and by commenting on the various stages of my manuscript. I am particularly grateful to the members of Lord Beveridge's family, Mr and Mrs Philip Mair and Professor Lucy Mair, for letting me loose on their family archives and for many helpful criticisms and suggestions. I also received valuable assistance from Miss Enid Chambers, Sir Norman Chester, Lord Chorley, Mr Martin Collier, Dame Marjorie Cox, Mr and Mrs John Dodd, Miss Eve Evans, Professor Arthur Goodhart, Sir Edward Hale, Professor Lancelot Hogben, Professor R. Klibansky, Lord Longford, Miss Muriel Ritson, Professor Philip Sargent Florence, Lady Stocks, Messrs Frank Thorold, Professor Richard Titmuss, Mrs Kay Titmuss, and Mrs Lucia Turin. I am grateful also to the following for permission to refer to unpublished copyright material deposited in libraries: Mr Derek Clarke of the British Library of Political Science; the Controller of HMSO; the Cabinet Office; the English Speaking Union; Mr S. H. G. Barnett; Lady Henderson; Mrs Margaret Lloyd; the Hon. Godfrey Samuel; Mr A. J. P. Taylor; Mr Michael Vyvyan, the Royal Economic Society; the Principal and Fellows of Newnham College, Cambridge; the Provost and Fellows of Corpus Christi College, Oxford; and Mrs Diana Wills. The book was started while I was a research fellow at Nuffield College, Oxford, and completed with the help of a research fellowship from the Centre for Studies in Social Policy. I am indebted to both those institutions for encouragement and support. In addition the Nuffield Foundation kindly gave me a grant from their 'small grants' scheme to assist with the costs of research. I should like also to thank colleagues at the London School of Economics and elsewhere for their helpful comments on earlier drafts, particularly Professor Brian Abel-Smith, Professor Garth Plowman, Dr Pat Thane, and Dr J. W. Harris. I am very grateful to Mrs Rose Parton and Miss Jean Seddon for their inexhaustible patience in typing a much- revised manuscript, and to Mrs Freda Chambers for help with indexing and correction of proofs. One fact that rapidly emerged from my research was that no two people held the same opinion of Beveridge. I doubt whether any of those named above will entirely concur in my interpretation -- the responsibility for which is of course mine alone.
