Helen Frankenthaler (1928-2011), whose career spanned six decades, has long been recognized as one of the great American artists of the twentieth century. She was eminent among the second generation of postwar American abstract painters and is widely credited for playing a pivotal role in the transition from Abstract Expressionism to Color Field painting. Through her invention of the soak-stain technique, she expanded the possibilities of abstract painting, while at times referencing figuration and landscape in unique ways. She produced a body of work whose impact on contemporary art has been profound and continues to grow.
