John 'Jack' Chambers (March 25, 1931–April 13, 1978) was a Canadian artist and filmmaker. Born in London, Ontario, Chambers' painting style shifted from surrealist-influenced to photo-realist. He began working with film in the 1960s, completing six by 1970. Stan Brakhage proclaimed Chambers' The hart of London as 'one of the greatest films ever made.'Brakhage, 123

Biography Chambers spent eight years (1953–1961) studying and working in Europe after studying at H.B. Beal Secondary School and the University of Western Ontario. While in Europe he met Pablo Picasso, who suggested he continue his studies in Madrid. He called his own work 'perceptual realism,'Chambers, 'Perceptual Realism', p. 34 a kind of surrealism based on his own dreams and memories and the existentialist philosophy of Maurice Merleau-Ponty. When he returned to London, Chambers worked with fellow London native Greg Curnoe.Elder, p. 7 In 1969 he was diagnosed with leukemia. For the rest of his life he painted more realistically, often depicting sites in London and the surrounding area. An example of this is 401 Towards London No. 1 (1968-1969), a view of Highway 401 heading westward towards London.
