Michael Craig-Martin was a pioneering figure in British Conceptual art during the late 20th century. Influenced by Minimalism and Dada, his early practice explored the boundaries between object and idea. Throughout his career, he has created sculptural ready-mades reminiscent of Marcel Duchamp, alongside vivid, graphic paintings of everyday objects. A central theme in his work is the relationship between object, image, and language—a conceptual thread that runs consistently through his oeuvre. His most iconic piece, An Oak Tree (1973), presents a glass of water on a shelf accompanied by a text asserting that it is, in fact, an oak tree—an ironic and philosophical gesture that exemplifies his wit and intellectual rigor. Craig-Martin’s influence has been profound, particularly among the Young British Artists, many of whom he mentored during his time at Goldsmiths' College. His work is held in major institutions including the Centre Pompidou, the Tate, the Victoria and Albert Museum, the British Council, and MoMA, and regularly commands six-figure sums on the secondary market.
