Leonard Brown was born and trained in Brisbane where he lives and works to this day. He is best known for his process based abstract oil paintings, created by controlling the pull of wet paint up, down, or around the canvas lent at certain angles. Colour and composition contribute to a wide range in the mood of the work, which can vary from serene minimalism to highly active optical abstraction. Less known, but carried out with equal vigour, are his Russian icon paintings created using traditional mediums and techniques.
Brown's work has been the subject of numerous solo and group exhibitions both throughout Australia and internationally. His work is held in many public and private collections, including the National Gallery of Australia Canberra; National Gallery of Victoria Melbourne; Art Gallery of New South Wales Sydney; Art Gallery of South Australia Adelaide; Art Gallery of Western Australia Perth; Queensland Art Gallery Brisbane; Queen Victoria Museum and Art Gallery Sydney; Australian Parliament House Collection Canberra; Brisbane City Gallery, Queensland; Chartwell Collection, Auckland Art Gallery Toi o Tāmaki New Zealand; University of Melbourne, Melbourne; LaTrobe University, Melbourne; Macquarie University, Sydney.
