Helen Frankenthaler (1928–2011), whose career spanned six decades, has long been recognized as one of the great American artists of the twentieth century. A member of the second generation of postwar American abstract painters, she is widely credited with 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 abstraction, while at times referencing figuration and landscape in highly personal ways. She produced a body of work whose impact on contemporary art has been profound and continues to grow.
