Helen Frankenthaler (1928 2011) has long been recognized as one of the great American artists of the twentieth century. A member of the second generation of American postwar abstract painters, she is widely credited with expanding the possibilities of abstraction through her invention of the soak-stain technique, and her highly personal references to figuration and landscape. This monograph is a revised and expanded edition of John Elderfield s landmark monograph (Frankenthaler, Harry N. Abrams, Inc., 1989) for the twenty-first century. It includes updated text throughout, along with a new chapter that covers work made post-1988. There are over 300 full-color reproductions of artworks by Frankenthaler, along with nearly 100 comparative illustrations and documentary photographs. As with the original book, this promises to be the definitive volume on Frankenthaler s career, written by the leading expert on her oeuvre.
