THE privilege afforded me by my friend the Author of participating in the production of a work on so epoch-marking a question as Zionism, has more than compensated me for any time and trouble I have expended on the particular section allotted to me. There are eighty-nine illustrations in the book, to which I have fortunately been able to contribute thirty, dealing mainly with the earlier period. For the portraits, _etc._, of many of our contemporaries, I must accord my sincere thanks to those whose courtesy and kindness have enabled me to carry out my purpose. I am indebted for the lithograph of Elim H. _d’_Avigdor¹ to his recently deceased widow. Mr. Semi Tolkowsky obtained for me an unpublished photograph of Colonel C. R. Conder from his daughter, Mrs. Julian G. Lousada. That venerable lady, Mrs. Finn, lent me a photograph of her late husband, “The British Consul of Jerusalem and Palestine.” Mr. Joseph Cohen Lask granted me the loan of the Hebrew periodical, _Keneseth Israel_, containing a woodcut of David Gordon, the editor. The celebrated artist, Leopold Pilichowski, entrusted me with the negative of his famous painting of Theodor Herzl, known as the “Congress” portrait. It was done from sketches taken from life during the Uganda Congress, and finished in 1906 to the order of the late President, David Wolffsohn, for the Actions Committee, to be exhibited at Zionist congresses. The illustration of _Grand Rabbin_ Zadok Kahn is taken from a pastel by the Jewish artist, J. F. Aktuaryus, in the collection of Mr. Elkan N. Adler. Dr. Hartwig Hirschfeld lent me a lithograph of his father-in-law, Dr. Louis Loewe; and Professor Dr. Arnold Netter sent from Paris a lithograph of his uncle, Charles Netter. The portrait of Laurence Oliphant was reproduced from an unpublished photograph in the possession of his relative, Mr. Lancelot Oliphant. To procure a likeness of Dr. M. J. Raphall I had some difficulty. The Birmingham congregation to whom he ministered from 1841‒1849 knew nothing of any portrait. From an advertisement in the _Jewish Chronicle_, 27 July, 1849, it appears that the learned _Rabbi_ possessed a painting done of him by W. H. Vernon, from which Mosely Levi of Birmingham produced a lithograph, but I failed to discover the whereabouts of either. Knowing that on leaving this country he settled in the United States, I communicated with Mr. Albert M. Friedenberg, the corresponding secretary of the American Jewish Historical Society, to whom my particular acknowledgments are due for discovering a small oil painting of the Doctor, copied from a photograph taken in his later years, in the possession of the _B’nai Jeshurun_ congregation of New York, whose _Rabbi_ he was from his arrival in America until 1866, two years before his demise. With the consent of the Trustees, and by the courtesy of Mr. Herman Levy, the President, an excellent reproduction was placed at my disposal.
