According to Wikipedia:
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.
Holzer’s initial public works, Truisms (1977–79), are among her best-known. They first appeared as anonymous broadsheets that she printed in black italic script on white paper and wheat-pasted to buildings, walls and fences in and around Manhattan. These one-liners are a distillation of an erudite reading list from the Whitney Independent Study Program, where she was a student. She printed other Truisms on posters, T-shirts and stickers, and carved them into stone benches. In late 1980, Holzer’s mail art and street leaflets were included in the exhibition Social Strategies by Women Artists at London’s Institute of Contemporary Arts, curated by Lucy Lippard.
