Beginning in the 1960s, Flavin transformed ordinary industrial materials—commercially available white and colored fluorescent tubes—into luminous wall-mounted, floor-based, and site-specific sculptures. These works, often composed of intersecting and parallel lines, saturate their surroundings with radiant color and light, redefining the viewer’s experience of space and drawing attention to the architectural environments they inhabit.One of Flavin’s most ambitious projects took place in 1992, when he installed a spectrum of fluorescent lights throughout the spiraling interior of Frank Lloyd Wright’s Guggenheim Museum in New York. This site-specific intervention activated the building’s iconic curves, fusing art and architecture in a striking visual dialogue.Flavin’s pioneering vision has been celebrated in major retrospectives at leading museums worldwide. His work is held in the permanent collections of institutions such as the Museum of Modern Art, Tate, the Hirshhorn Museum and Sculpture Garden, the Kunstmuseum Basel, the S.M.A.K. Museum of Contemporary Art, and the Whitney Museum of American Art. Highly sought after in the art market, Flavin’s works have achieved seven-figure results at auction, reflecting his enduring influence on contemporary art.
