American artist and theoretician Joseph Kosuth is considered one of the originators of Conceptual and installation art. Exploring the relationship between words and objects, between language and meaning in art, Kosuth has initiated language-based artworks and appropriation strategies since the 1960s. While believing that an artist’s medium is meaning, not simply form and color, Joseph Kosuth’s work has taken the form of objects, installations, texts, publications and projects in public spaces. By using words in place of visual imagery of any kind, the artist was decisively involved in starting a trend that favored an artwork’s idea or concept over a physical object. His first conceptual artwork from 1965, One and Three Chairs, in which he assembled an actual wooden chair, the photograph of that chair, and an enlarged photographic copy of the dictionary definition of the word ‘chair’, explored the role of of language, appropriation and meaning in art. “The art I call conceptual is such because it is based on an inquiry into the nature of art,” Kosuth has written. His early works were first shown in 1967 at a space co-founded by the artist, known as the Museum of Normal Art. In 1969, Joseph Kosuth held his first solo show at Leo Castelli, and became an editor for the Art and Language journal. His art has influenced a generation of Conceptual artists, including Jenny Holzer and Barbara Kruger. He has participated at documenta and the Venice Biennale four times each and held major solo exhibitions at institutions including MAMM (Moscow), the Louvre (Paris), the Schirn Kunsthalle (Frankfurt), the Tokushima Modern Art Museum, the Palais des Beaux Arts (Brussels) and the MoMA PS1 (New York). Joseph Kosuth was born 1945 in Toledo, Ohio (USA) and lives and works in New York and London.
