When asked to describe her painting Chairman of the Board (1972), Helen Frankenthaler said it “was about a grand sweep. I had the basic idea in my head—I knew how the lines would dance in. I felt sure of myself.” You could say that Frankenthaler’s career was a series of grand sweeps. In the 1950s, she pioneered the practice of pouring thin oil paint onto canvas, a new form of abstraction. Later, she swept through the midcentury New York art scene and contributed to the rise of Abstract Expressionism. In the 1980s, she made sweeping gestural prints and radiant landscapes, expanding her vocabulary while remaining unmistakably herself. This exhibition of paintings explores Frankenthaler’s confidence with color, her fluency of line, and the pleasure she took in the act of making. —Elena Clavarino
