Kristján Guðmundsson (born 1941) is a contemporary Icelandic conceptual artist. He started his career as an artist in the 1960s as a member of SÚM – a group of young artists influenced by then-new currents in conceptual and installation art. Guðmundsson’s art reflects both prevailing traditions in late 20th century western art in general, and the dominance of abstract and conceptual art in the post-war art of Iceland in particular. He has said, “I am trying to work within the field of tension that exists between nothing and something”.
