Louise Nevelson (September 23, 1899 – April 17, 1988) was an American sculptor known for her monumental, monochromatic, wooden wall pieces and outdoor sculptures. Born in Czarist Russia, she emigrated with her family to the United States in the early 20th century. Nevelson learned English at school, as she spoke Yiddish at home. By the early 1930s she was attending art classes at the Art Students League of New York, and in 1941 she had her first solo exhibition. A student of Hans Hofmann and Chaim Gross, Nevelson experimented with early conceptual art using found objects, and dabbled in painting and printing before dedicating her lifework to sculpture. Usually created out of wood, her sculptures appear puzzle-like, with multiple intricately cut pieces placed into wall sculptures or independently standing pieces, often 3-D. A unique feature of her work is that her figures are often painted in monochromatic black or white. A figure in the international art scene, Nevelson was showcased at the 31st Venice Biennale. Her work is seen in major collections in museums and corporations. Louise Nevelson remains one of the most important figures in 20th-century American sculpture.
