, Birmingham John stopped exhibiting at the NEAC in 1911, but gained an important patron in
John Quinn, an American art collector who, from 1910 until his death in 1924, purchased the majority of the works that Gwen John sold. Quinn's support freed John from having to work as a model, and enabled her to devote herself to her work. Although she participated in exhibitions fairly regularly, her perfectionism produced in her a marked ambivalence toward exhibiting. She wrote in 1911: "I paint a good deal, but I don't often get a picture done—that requires, for me, a very long time of a quiet mind, and never to think of exhibitions." Her attitude towards her work was both self-effacing and confident. After viewing an exhibition of watercolours by
Cézanne she remarked: "These are very good, but I prefer my own." About 1913, as an obligation to the
Dominican Sisters of Charity at Meudon, she began a series of painted portraits of
Mère Marie Poussepin (1653–1744), the founder of their order. These paintings, based on a prayer card, established a format—the female figure in three-quarter length seated pose—which became characteristic of her mature style. She painted numerous variants on such subjects as
Young Woman in a Spotted Blue Dress,
Girl Holding a Cat and
The Convalescent. The identities of most of her models are unknown. In Meudon John lived in solitude, except for her cats. In an undated letter, she wrote: "I should like to go and live somewhere where I met nobody I know till I am so strong that people and things could not effect me beyond reason." She wished also to avoid family ties ("I think the family has had its day. We don't go to Heaven in families now but one by one") and her decision to live in France after 1903 may have been the result of her desire to escape the overpowering personality of her famous brother, although, according to the art historian David Fraser Jenkins, "there were few occasions when she did anything against her will, and she was the more ruthless and dominating of the two". John exhibited in Paris for the first time in 1919 at the
Salon d'Automne, and exhibited regularly until the mid-1920s, after which time she became increasingly reclusive and painted less. She had only one solo exhibition in her lifetime, at the
New Chenil Galleries in London in 1926. In that same year she purchased a bungalow in Meudon. In December 1926, distraught after the death of her old friend Rilke, she met and sought religious guidance from her neighbour, the neo-Thomist philosopher
Jacques Maritain. She also met Maritain's sister-in-law, Véra Oumançoff, with whom she formed her last romantic relationship, which lasted until 1930. It is not known when Gwen first became involved with the
Royal Academy of Arts, London, but before she died, she resigned from her position. John's last dated work is a drawing of 20 March 1933, and no evidence suggests that she drew or painted during the remainder of her life. On 10 September 1939, she wrote her will and then travelled to
Dieppe, where she collapsed and was hospitalised. She died there on 18 September 1939 and was buried in Janval Cemetery. According to
Paul Johnson in
Art: A New History, "she appears to have starved to death". == Artistic approach ==
