Sarah Grilo was born in Buenos Aires in 1920 and studied with the Spanish painter Vicente Puig until 1943. Grilo began her artistic career painting geometric abstractions. Her early works consisted of images of loosely painted interlocking circles and planes in bright colors. She painted freehand, filling her canvases with irregularly formed shapes and working the paint with a brush or palette knife to emphasize its texture. Her work had an emotional quality that contrasted with that of the Concrete artists, who preferred hard-edged, mechanical compositions and who dominated the art scene in Argentina during the early 1950s. Like that of her husband, José Antonio Fernández-Muro, Grilo’s work is often considered to bridge the strict geometry of the Concrete artists and the more gestural, expressionistic work of the New Figuration artists. After receiving a Guggenheim fellowship in 1962, Grilo moved to New York with Fernández-Muro, where they remained until 1969.
