On the Passage of a Few People Through a Rather Brief Moment in Time: The Situationist International 1956-1972 (1989)

The Situationist International (SI) was an international organization of social revolutionaries made up of avant-garde artists, intellectuals, and political theorists, prominent in Europe from its formation in 1957 to its dissolution in 1972. The intellectual foundations of the Situationist International were derived primarily from anti-authoritarian Marxism and the avant-garde art movements of the early 20th century, particularly Dada and Surrealism.
