Ross Feld completed the manuscript of Guston in Time in the fall of 2000 and asked several of Philip Guston’s friends and associates to review it for factual accuracy. Before his death in May 2001, however, Feld did not have an opportunity to revisit the text of Guston in Time. The editors gratefully acknowledge the generous assistance of Musa Mayer, David McKee, Archie Rand, Ellen Feld, and Larry Merrill in sharing their knowledge of Philip Guston and Ross Feld (and in making available Feld’s notes and previous writings on Guston), so that the handful of final revisions that Feld contemplated could be completed. Jan C. Grossman and Herbert Leibowitz also provided invaluable advice and assistance in the preparation of this book.
