http://www.nytimes.com/2007/09/28/arts/28tawney.html?n=Top%2FReference%2FTimes%20Topics%2FSubjects%2FA%2FArt"Lenore Tawney, an artist whose monumental sculptural weavings redefined the possibilities of both sculpture and weaving in the second half of the 20th century and helped create the genre of fiber art, died Monday at her home in Manhattan. She was 100.
In the late 1950s and early 1960s, when art and crafts were viewed in America as mutually exclusive disciplines, Ms. Tawney united them decisively and controversially. Trained as a sculptor and as a weaver, she combined several different techniques — plain weave, gauze weave, slit tapestry and open-warp weaving — to invent large, abstract and free-standing, or rather free-hanging, sculptural forms."
