Art & Language
http://en.wikipedia.org/wiki/Art_&_Language
The Art & Language group was founded in 1968 in the United Kingdom by artists Terry Atkinson (b. 1939), David Bainbridge (b. 1941), Michael Baldwin (b. 1945) and Harold Hurrell (b. 1940), four artists who began collaborating around 1966 while teaching art in Coventry. Their early work, as well as their journal Art-Language, first published in 1969, is regarded as an important influence on much conceptual art both in the United Kingdom and in the United States. The name of the group was derived from the journal, which existed as a work in conversation as early as 1966.
In the early 1970s Ian Burn, Michael Corris, Charles Harrison, Preston Heller, Graham Howard, Joseph Kosuth, Andrew Menard, Mel Ramsden, Terry Smith and from Coventry Philip Pilkington and David Rushton merged their work with Art & Language. Burn and Ramsden co-founded The Society for Theoretical Art and Analysis in New York in the late 1960s.
