Born in Margaret River in 1953, Alan Muller achieved equal top marks in Western Australia for Art in the Leaving Certificate and was awarded a Commonwealth Scholarship for tertiary studies in 1970. In 1977 he exhibited paintings professionally for the first time in the Seven Young Western Australian Artists at the Undercroft Gallery, University of Western Australia [UWA]. His first solo exhibition of paintings was in 1980 at Fremantle Arts Centre. Three solo exhibitions followed at Gallery 52, Claremont that included two portraits that were finalists in the Archibald Prize, Art Gallery of New South Wales. These were a portrait of George Haynes in 1983 and a self portrait in 1984.
Muller has held many solo exhibitions and in 2017 held A Retrospective of Paintings 1997 – 2017 at Wanneroo Cultural Centre. His work is held in significant collections across Australia including Artbank.
