Mary was educated in Cornwall and Devon and studied at the St. Ives School of Art under Leonard Fuller who first opened the school in 1938. During the War she worked as a draughtsman for the Charts Department of the Admiralty, relocated to Bath. Afterwards the family removed to Knightsbridge in London and she completed a five-year Diploma at the RA schools, earning silver medals for painting and drawing and the David Murray scholarship for landscape.
Mary’s work consists largely of portraits; remarkable for its range, demonstrating her dexterity in so many media and that she is somewhat, an artistic polymath. She has a long and distinguished exhibiting career at the Royal Academy, the Royal Society of Portrait Painters and the Royal Society of Miniaturists and not least amongst the regional Art Societies.
She lives in retirement in Norfolk where she works and exhibits for the most part, locally. Her work resides in private and public collections in the UK, Europe, Russia, South America, the US and Jamaica.
