Joseph Kosuth was born in 1945 in Toledo, Ohio. He studied at the Toledo Museum School of Design from 1955 to 1962, and then at the Cleveland Institute of Art from 1963 to 1964. Finally, from 1965 to 1967 he attended the School of Visual Arts in New York. In this period Kosuth began to produce his conceptual work based on language. In 1965 he exhibited his One and Three Chairs, a work that presented a single chair in three ways: as a real object, as a photograph, and in the form of a dictionary definition. The theoretical importance of a work is of great significance for him. He began editing the American edition of the magazine Art-Language in 1969. Kosuth completed his studies at the New School for Social Research in 1971/1972, and then served as art editor for the periodical Marxist Perspectives. He taught from 1988 to 1990 at Hamburg’s main art school, the Hochschule für bildende Künste, and then from 1991 to 1997 at its counterpart in Stuttgart, the Staatliche Akademie der bildenden Künste. His works have been seen in numerous exhibitions, including documenta 5, 6, 7 and 9 (1972, 1977, 1982, 1992) and four shows at the Venice Biennale. Kosuth lives and works in New York.
