The man we have to deal with had something excessive about him; he was
headstrong, tactless, impractical, enormously energetic, a prodigious
worker, a conceiver of grandiose projects, and a relentless hunter of
patrons. He was at home with his social superiors and had some
pretentions to literary culture, he had a coarse gift for the vivid
phrase in writing, and his tastes in art ran to the classic and heroic.

This study includes an illustrated catalog of Jackson's chiaroscuros and
color prints. Previous catalogs, notably those of Nagler, Le Blanc, and
Heller, have listed no more than twenty-five works. The present catalog
more than triples this number.

To acknowledge fully the assistance given by museum curators,
librarians, archivists, and scholars on both sides of the Atlantic would
necessitate a very long list of names. However, I wish especially to
thank Mr. Peter A. Wick of the Museum of Fine Arts, Boston, who has been
generous enough to allow me to read his well-documented paper on
Jackson's Ricci prints; Mr. A. Hyatt Mayor of the Metropolitan Museum of
Art; Mr. Carl Zigrosser of the Philadelphia Museum of Art; Miss Anna
C. Hoyt and Mrs. Anne B. Freedberg of the Museum of Fine Arts, Boston;
Dr. Jakob Rosenberg and Miss Ruth S. Magurn of the Fogg Art Museum; Mr.
Karl Kup of the New York Public Library; Miss Elizabeth Mongan of the
Rosenwald Collection, National Gallery of Art; Miss Una E. Johnson of
the Brooklyn Museum; Mr. Gustave von Groschwitz of the Cincinnati Art
Museum; and Dr. Philip W. Bishop of the U.S. National Museum,
Smithsonian Institution.

I am particularly grateful to curators of European collections, who have
been uniformly generous in their assistance. Special thanks are due Mr.
J. A. Gere of the British Museum and Mr. James Laver of the Victoria and
Albert Museum, who have gone to considerable trouble to acquaint me with
their great collections. Others whose help must be particularly noted
are Mr. Peter Murray, Courtauld Institute of Art, University of London;
Mme. R. Maquoy-Hendrickx of the Bibliotheque Royale de Belgique,
Brussels; Dr. Vladimir Novotny of the Narodni Galerie, Prague; Dr.
Wegner of the Graphische Sammlung, Munich; Dr. Wolf Stubbe of the
Kunsthalle, Hamburg; Dr. G. Busch of the Kunsthalle, Bremen; Dr. Hans
Moehle of the Staatliche Museen, Berlin; Dr. Menz of the Staatliche
Kunstsammlungen, Dresden; Miss B. L. D. Ihle of the Boymans Museum,
Rotterdam; and M. Jean Adhema
