Acknowledgments

Philip Guston's acquaintances and friends have been exceptionally generous in discussing their relationships with him, and in providing information in documentary form. Among those whose help was essential were Reuben Kadish, Stephen Greene, and Fletcher Martin, all of whom I thank warmly, as well as James Brooks, Robert Phelps, Harold Lehman, JoEllen Rapee, Morton Feldman, Philip Roth, Clark Coolidge, and Mercedes Matter. I thank Harold Rosenberg and Andrew Forge for sharing my enthusiasm; Musa Guston for her unstinting assistance; Denise Hare for her uncanny ability to capture in photographs the ambiance of Guston's studio, and Gayle Ellis for her constancy as my secretary. Special thanks to David and Renée McKee, who were admired and appreciated by Guston, as they are by me.
