Renowned sculptor Louise Nevelson started as a social realist painter, training with Theresa Bernstein and Diego Rivera. She confronted sexism early in her career when a critic was appalled that her work was made by a woman. In the 1950s, Nevelson joined the National Association of Women Artists and soon found her métier in abstract sculpture. Applying paint-most famously black, but also white and gold-to found wooden objects, she pieced together room-size constructions evoking social situations. In the 1970s, Nevelson identified with radical women's groups like Ti-Grace Atkinson's The Feminists and simplified her system of shadow boxes and painterly illusionism, proclaiming, "I am a woman's liberation." At The Jewish Museum, Nevelson's work has been shown in nine group shows and was featured in a retrospective in 2007.
