Diana Armfield studied at the Slade School and Central School of Arts and Crafts. She is known not only as a painter but also for her early textile and wallpaper designs which are included in the permanent collection of the Victoria and Albert Museum, London. Landscape is a major subject in her work, as well as still lives and interiors. She invariably works within a small format never exceeding 50X 60 cms. Between June 2002 and May 2002, Diana Armfield was interviewed, and these records now form part of the aural archive at the British Library.
Commenting on her work, Diana Armfield has said:
'If I'm landscape painting, I may be looking for the subject in those places which appear at first unruly- wild country, sea or sky, tumbling rocks. All are subject to the big ordering forces of the weather, growth of seasonal change.... Or I look at those parts where man has modified the landscape; vineyards, olive groves, quarries, towns.'
Since 1965 Diana Armfield has been a regular exhibitor at the Royal Academy, New Grafton Gallery, New English Art Club and Browse and Darby, London, amongst other venues. She has work in the Royal West of England Gallery Permanent Collection as well as numerous other public and private collections. She holds membership to the Royal Academy and New English Art Club as well as the RWA. Twice she reached the finals of the Hunting Prize in the 1980's and she won the Agnew's New English Art Club Prize in the early 1990's.
