Conceptual artist Michael Craig-Martin is best known for his representation of everyday objects with boldly outlined motifs and luridly vivid colour schemes in unexpected combinations in both paintings and sculptures. He has also had a huge influence on other artists. Teaching at Goldsmith's College School of Art from 1974–88 and 1994–2000 he was a powerful influence on the Young British Artists, including Gary Hume, Sarah Lucas, and Damien Hirst.
Born in Dublin in 1941 Michael Craig-Martin grew up and was educated in the United States and studied Fine Art at Yale. In 1966 he moved to London where he has lived ever since. His early work drew together a variety of objects and materials and questioned the nature of art and representation. An Oak Tree, 1973, is one of his best known early works.
