Nancy Holt (1938–2014) was a member of the Earth, Land, and Conceptual Art movements. A pioneer of site-specific installation and the moving image, Holt recalibrated the limits of art. She expanded the places where art could be found and embraced the new media of her time. Across five decades she asked questions about how we might understand our place in the world, investigating perception, systems, and place. Holt’s rich artistic output spanned concrete poetry, audioworks, film and video, photography, slideworks, ephemeral gestures, drawings, room-sized installations, earthworks, artists’ books, and public sculpture commissions.  
Born in Worcester, Mass., she grew up in New Jersey and graduated with a degree in biology from Tufts University in 1960. Later that year she moved to New York City where she met the artist Robert Smithson; the two were married in 1963. Holt’s work is held in major collections including Museum of Modern Art, New York; Museum für Gegenswartkunst, Germany; Utah Museum of Fine Arts; and Whitney Museum of American Art, New York. In 2018 Sun Tunnels and Holes of Light were acquired by Dia Art Foundation, with support from Holt/Smithson Foundation.
