Joseph Kosuth (b. 1945, lives and works in New York and Rome)is one of the pioneers of Conceptual art and installation art who initiated language-based works and appropriation strategies in the 1960s. His installations, museum exhibitions, public commissions, and publications have consistently explored the production and role of language and meaning within art. His work has been exhibited throughout Europe, the Americas and Asia, including five Documenta(s) and six Venice Biennale(s). Currently, he is Professor at Istituto Universitario di Architettura (Venice). Kosuth’s exhibition ni apparence ni illusion, an installation work in white neon that runs for 280 meters along the original 12th century medieval walls of the Louvre Palace, opened in October 2009 at the Musée du Louvre (Paris).
