Wikipedia: David UU (pronounced David W.), or David W. Harris, (1948"“1994) is considered an accomplished concrete and experimental poet and an important small press publisher. Along with bill bissett and bpNichol, he was a pioneer of the concrete poetry movement in Canada, and perhaps the first Canadian poet to explore visual collage embodying literary, philosophical and language references. He also composed sound works (both musical & textual), made 8mm short films, was a master collagist/montagist and performed in numerous performance art exhibitions. David W. Harris was born on June 13, 1948, in Barrie, Ontario. The family moved to Collingwood in 1958, where he lived until setting out for Toronto in 1966. He left Toronto for Vancouver in 1968 and over the next decade relocated between Ontario and the west coast several times. In 1980 he settled in North Vancouver where he lived until finally moving to a farmhouse near Delhi, Ontario in 1992 where he died in May, 1994. On arriving in Toronto in 1966, Harris began working closely with bpNichol on various text and sound projects. He participated in the founding of the concrete poetry magazine grOnk with bpNichol and others. At this time he began exhibiting his visual poetry and collage worldwide, achieving some acclaim. Harris adopted the pseudonym David UU around 1970. In Vancouver in 1973 he helped organize Brasilia 73, an international concrete poetry show. He was a prolific publisher and encouraged the talents of many Canadian writers early in their careers. He founded and operated Fleye Press (1966"“70), Divine Order of the Lodge (1971"“1975), Derwyddon Press (1976"“81), Silver Birch Press (1987"“94) as well as several magazines and numerous imprints for booklets, pamphlets, broadsides, postcards and other ephemera. -- Source of annotation: Marvin or Ruth Sackner.
