Jenny Holzer (born July 29, 1950, Gallipolis, Ohio) is an American neo-conceptual artist, based in Hoosick Falls, New York. The main focus of her work is the delivery of words and ideas in public spaces.

Holzer belongs to the feminist branch of a generation of artists that emerged around 1980, looking for new ways to make narrative or commentary an implicit part of visual objects. Her contemporaries include Barbara Kruger, Cindy Sherman, Sarah Charlesworth, and Louise Lawler.

The public dimension is integral to Holzer's work. Her large-scale installations have included advertising billboards, projections on buildings and other architectural structures, and illuminated electronic displays. LED signs have become her most visible medium, although her diverse practice incorporates a wide array of media including street posters, painted signs, stone benches, paintings, photographs, sound, video, projections, the Internet, and a race car for BMW. Text-based light projections have been central to Holzer’s practice since 1996. As of 2010, her LED signs have become more sculptural. Holzer is no longer the author of her texts, and for the past five years, she has returned to her roots by painting.

Syracuse University, the School of Visual Arts, and studying art and design with Diane Arbus at Parson’s School of Design in New York, Kruger obtained a design job at Condé Nast Publications. Working for Mademoiselle Magazine, she was quickly promoted to head designer. Later, she worked as a graphic designer, art director, and picture editor in the art departments at House and Garden, Aperture, and other publications. This background in design is evident in the work for which she is now internationally renowned. She layers found photographs from existing sources with pithy and aggressive text that involves the viewer in the struggle for power and control that her captions speak to. In their trademark black letters against a slash of red background, some of her instantly recognizable slogans read “I shop therefore I am,” and “Your body is a battleground." Much of her text questions the viewer about feminism, classicism, consumerism, and individual autonomy and desire, although her black-and-white images are culled from the mainstream magazines that sell the very ideas she is disputing. As well as appearing in museums and galleries worldwide, Kruger’s work has appeared on billboards, buscards, posters, a public park, a train station platform in Strasbourg, France, and in other public commissions. She has taught at the California Institute of Art, The School of the Art Institute of Chicago, and the University of California, Berkeley. She lives in New York and Los Angeles.
