Lettrism
（重定向自Letterist）
Lettrism is a French avant-garde movement, established in Paris in the mid-1940s by Romanian immigrant Isidore Isou. In a body of work totaling hundreds of volumes, Isou and the Lettrists have applied their theories to all areas of art and culture, most notably in poetry, film, painting and political theory. The movement has its theoretical roots in Dada and Surrealism. Isou viewed his fellow countryman, Tristan Tzara, as the greatest creator and rightful leader of the Dada movement, and dismissed most of the others as plagiarists and falsifiers. Among the Surrealists, André Breton was a significant influence, but Isou was dissatisfied by what he saw as the stagnation and theoretical bankruptcy of the movement as it stood in the 1940s.
