1959 Born Chigwell 1978-81 Chelsea School of Art, London 1983-85 Goldsmiths College, London Lives and works in London Mark Wallingers work is noted for its succinct social commentary and political resonance. His early work explored the values of contemporary British society, in particular national identity. His focus subsequently expanded to address themes of death and religion. Despite dealing with such expansive themes, his work is often characterised by a lightness of touch that belies the serious and multifaceted nature of the subject matter. Sleeper records a live performance in which the artist, alone and dressed in a bear suit, occupied Berlins Neue Nationalgalerie for ten consecutive nights. The museums location enables a diversity of themes to converge, creating a uniquely complex and unsettling work. The bears in the nearby historic Zoo are doomed never to reproduce, the possibility of their procreation in captivity preordained and controlled by man. Fortified by a culture of surveillance and paranoia, Berlin during the Cold War was physically, politically and socially divided. The sleepers, or double agents, blended into their surroundings by sporting plausible disguises. Wallinger, a Briton in a foreign city, disguises himself as a bear - the heraldic emblem of Berlin - an appropriation in which he becomes both bear and simultaneously not bear. Wallinger has described how the idea of a divided realm exists within his subconscious, shaped by a German fairy tale in which a prince is transformed into a bear. In Sleeper the Marxist dictum in which history returns first as tragedy then as farce is wryly expressed. Allegory, the repression of memory, and the mutability of national identity combine to offer a meditative exploration of the language of representation, as well as an examination of the nature of perception itself. Mark Wallinger is nominated for his exhibition StateBritain at Tate Britain.
