I WOULD like to acknowledge the help of a number of archivists and librarians, in particular Esra Kahn and Aron Prys of the London School of Jewish Studies; Dalia Tracz of the Mocatta Library; and the staff at the British Library, the Law Society library, the Wellcome Library, and my local library in Swiss Cottage.

One discovery I made over the course of my researches was that the facilities for exploring the history of medicine are far superior to those existing for the study of the history of the legal profession; I would suggest, therefore, that there is a need for barristers and solicitors to set up a centre comparable to the Wellcome Library. I was fortunate, though, that my friend Graham Drucker allowed me to select books from his late brother Leon's collection; these provided many unexpected insights into the lives of Jewish lawyers.

Finally, I would like to thank all those who generously agreed to be interviewed and then tolerated what I had to say about them. The list of names is too long for them all to appear here, but everyone concerned is duly mentioned in the text and notes that follow. My thanks are also due to Mr David Freeman for allowing me to use material collected by his late wife Iris for her projected biography of Lord Goodman; to Dr Martin Sarner for making available data which he had compiled on London's Jewish doctors; to Dr Charles Daniels for giving me access to the pre-war records of the London Jewish Medical Society; to Dr Philip D'Arcy Hart for permitting me to look at records held by him; to Mrs Madeleine Gottlieb and her husband Craig for allowing me to inspect the papers of her late father Joseph Jackson; to Mrs Jessica Gillis for allowing me to see her husband's unpublished memoirs; and to Daniel Lightman, who gave me access to material on the career of his grandfather, Harold Lightman. My brother Rabbi Dr Martin Cooper has been a steady source of encouragement and help to me throughout the project. I have also benefited from the assistance of Judge Israel Finestein QC, Henry Grunwald QC, Dr Gerry Black, Dr Mervyn Goodman, Dr Joyce Bourne, Emma Klein, Aubrey Silverstone, Murray Freedman, and the late Monty Dobkin and Richard Sherrington.
