(movement, 1957-1972)
The Situationist International (SI)(1957-1972) was an international but Paris-based formation which recreated the avant garde tradition on a high plane of intelligence and intransigence. Best known today for its ultra-left politics, the SI was founded by artists who merged two tiny organizations, the Lettrist International (starring filmmaker Guy Debord and his wife Michele Bernstein, a collage artist) and the International Movement for an Imaginist Bauhaus (including painters Asger Jorn and Giuseppe Pinot-Gallizio).
