Jackson, Sam Middleton, Larry Potter, Haywood Bill Rivers, Merton Simpson, and Walter Williams. Some African-American artists did make it into important New York galleries by the 1950s and 1960s: Horace Pippin, Romare Bearden, Jacob Lawrence, Richard Hunt, William T. Williams, Norman Lewis, Thomas Sills, and Sam Gilliam were among the few who had successfully been received in a gallery setting. Richard Hunt was the first African American visual artist to serve on the National Council on the Arts, appointed by President Lyndon B. Johnson in 1968. Hunt was the fourth African American on the council, after Marian Anderson, Ralph Ellison, and Duke Ellington. In 1971, Richard Hunt was the first African American sculptor to have a major solo retrospective at the Museum of Modern Art. The Civil Rights Movement of the 1960s and 1970s led artists to capture and express the changing times. Galleries and community art centers developed for the purpose of displaying African-American art, and collegiate teaching positions were created by and for African-American artists. Some African-American women were also active in the feminist art movement in the 1970s. Faith Ringgold made work that featured black female subjects and that addressed the conjunction of racism and sexism in the U.S., while the collective Where We At (WWA) held exhibitions exclusively featuring the artwork of African-American women. By the 1980s and 1990s, hip-hop graffiti began to predominate in urban communities. Most major cities had developed museums devoted to African-American artists. The National Endowment for the Arts provided increasing support for these artists. Late 20th/early 21st century Kara Walker, a contemporary American artist, is known for her exploration of race, gender, sexuality, violence and identity in her artworks. Walker's silhouette images work to bridge unfinished folklore in the Antebellum South and are reminiscent of the earlier work of Harriet Powers. Her nightmarish yet fantastical images incorporate a cinematic feel. In 2007, Walker was listed among Time magazine's "100 Most Influential People in The World, Artists and Entertainers". Textile artists are part of African-American art history. According to the 2010 Quilting in America industry survey, there are 1.6 million quilters in the United States.
