Mary Potter, OBE (9 April 1900 – 14 September 1981) was an English painter whose best-known work uses a restrained palette of subtle colours.
After studying at the Slade School of Fine Art, Potter began her career, exhibiting in London by the early 1920s. From the 1950s, her work became increasingly abstract, and she gained wider notice.
Potter was born Marian (Mary) Anderson Attenborough in Beckenham, Kent. Her parents were Arthur (John) Attenborough (1873–1940), a solicitor, and his wife, Kathleen Mary, née Doble (1872–1957). Potter attended St Christopher's school in Beckenham, and the Beckenham School of Art. She studied under Henry Tonks at the Slade School of Fine Art, beginning in 1918, where she won many prizes including the first prize for portrait painting
After leaving school, she shared a studio in Fitzroy Street in London's bohemian Fitzrovia neighborhood, became a member briefly of the Seven and Five Society and exhibited with The New English Art Club and The London Group. She worked in oil paint and watercolours. She was married to the writer and radio producer Stephen Potter from 1927 to 1955, and the couple had two children, Andrew (born 1928) and Julian (born 1931). Her first solo exhibition was in 1932 at the Bloomsbury Gallery in London. During the Second World War, the family moved out of London but returned soon afterwards. Her paintings ranged from still lifes and landscapes to portraits, including one of Joyce Grenfell.
In 1951, Potter moved with her husband to Aldeburgh on the east coast of Suffolk and lived in The Red House which she swapped, in 1957, for Crag House, owned by Benjamin Britten, with whom she became a close friend after her divorce in 1955. With her children grown, she spent long hours painting. By mixing paint with beeswax, she achieved a "chalky luminous quality" using a "pale and subtle" range of colours, and her work grew increasingly abstract. In his essay for the catalogue of her 1965 Whitechapel Art Gallery exhibition, Mary Potter Paintings 1938–1964, museum director Kenneth Clark said Potter's works "exist in the domain of seeing and feeling; we know that they are exactly right in the same way that we know a singer to be perfectly in tune"; he described her paintings as "enchanting moments of heightened perception".
