For more than forty years, Jenny Holzer has presented her astringent ideas, arguments and sorrows in public places and international exhibitions, including Times Square, the Venice Biennale, the Guggenheim Museums in New York and Bilbao, and the Louvre Abu Dhabi. Her medium, whether a T-shirt, plaque or electronic sign, is writing, and the public dimension is integral to her work. Starting in the 1970s with street posters in New York City and continuing through her recent light projections on landscape and architecture, her practice has rivalled ignorance and violence with humour, kindness and courage.
