Following years of scientific research into the source of human aesthetics, Frank Avray Wilson became a pioneer of early British post-war Abstract Expressionism. Once he discovered that colour is not matter but energy, that an image could be as alive as a living cell under a microscope, and that human art-making is a reflection of Nature's art making, Avray Wilson arrived at full gestural painting in the early 1950s. By the 1960’s Avray Wilson had exhibited widely in the United Kingdom, France, the United States and Japan. During a varied career Avray Wilson has been a lecturer and author, whose works include ‘Art as Understanding' and 'Art as Revelation'.

Avray Wilson's paintings are present in the following museums: British Museum, London; Carnegie Institute, Pittsburgh, USA; Cleveland Museum of Modern Art, Ohio, USA; Fitzwilliam Museum, Cambridge; The Walker Art Gallery, Liverpool; Leicester Museum and Art Gallery, Leicester; Northampton Museum and Art Gallery, Northampton; Southampton City Art Gallery, Southampton; Toledo Art Gallery, Ohio, USA; Victoria and Albert Museum, London.
