Jiří Kolař (Protivín, 1914 - Prague, 2002) was one of the most important postwar poets/visual artists in Central Europe. A member of the avant-garde Group 42 in Czechoslovakia, most of his major texts were composed in the 1950s and 1960s. He is, however, more well-known abroad for his collage innovations, including his famous series Weekly 1968. Having developed a technique for combining fragments of texts and images from a variety of sources as a way to portray the destruction and fragmentation of the world around him, by the 1970s his work was being exhibited throughout Europe.
