Sophie Brzeska

Sophie Suzanne Brzeska or Sophie Gaudier-Brzeska (born Zofia Brzeska; 8 June 1872 – 17 March 1925) was a Polish writer and artistic muse most noted for being the companion of the artist Henri Gaudier-Brzeska. 
Brzeska and Gaudier met in 1909 in Paris and began an intense relationship. Henri annexed her surname although they never married. Much of what scholars and historians have been able to trace about Sophie Brzeska has come from her personal correspondence with Gaudier. H. S. Ede acquired her papers after her death and drew extensively on her writing when he published "A Life of Gaudier-Brzeska" (1930).
Early years.
Sophie Brzeska was born near Kraków, Poland in 1873 to a family of 11. She described her mother as "weary" and her father as "womanising", both believing she was a "burden needing to be married off." She resisted and fled Poland for Paris to become a writer. She accepted a succession of jobs as governess, one of which involved her living in the United States for several years. These ventures with other people's families left her contemplating suicide. 
Life with Henri Gaudier-Brzeska.
Brzeska and Gaudier met in 1909 at the Bibliothèque Sainte-Geneviève in Paris, and began an intense symbiotic relationship. Gaudier (born 1891) described her in a letter to a friend as "a Polish ex-governess twice his age." 
Brzeska was a companion and her relationship with Gaudier resembled a co-dependency because both suffered from mental health issues and stress brought on by poverty. Henri was devoted to Sophie, even taking her last name as his, but Sophie often was dismissive and cold toward Henri's romantic overtures (according to Ede, they never had sex or only once or twice or rarely). They were often apart, and Sophie would buy Henri prostitutes for his enjoyment instead of having sexual relations with him.
Writings.
Sophie Brzeska referred constantly to her "work" and aspirations to be a published writer. She wrote a number of versions of her autobiography entitled "Matka" but nothing in her own words was published until 2008. The book "Matka and Other Writings" (London: Mercury Graphics; includes some texts translated from French by Gillian Raffles) is from manuscript sheets which have lain forgotten and unpublished for over 50 years. One part of this group of papers is a version of "Matka", and it includes her first meeting and her life with Henri Gaudier, and their adoption of the name Gaudier-Brzeska. It contains her account of what happened to her immediately after Henri Gaudier-Brzeska was killed at the Front in France in 1915, graphically recounts her efforts and trials to arrange a memorial exhibition of his work, and gives a frank view of how she felt his friends T. E. Hulme, Ezra Pound, Robert Bevan and others behaved toward her. Also included are later postcards and letters to the artist Nina Hamnett.
Brzeska wrote in both French and English, and it is clear from the language and tempo of the writings that she was highly strung and emotional. When writing in English, her spelling becomes progressively more chaotic as did her handwriting in both languages. The intention of the editor has been to keep these elements evident in the translation and transcription in order to be true to her character and escalating emotional intensity and to hear her unique voice. Her ignoring of conventional punctuation has been retained for the same reason.
Long an admirer of Gaudier's work, the art collector and historian H. S. Ede acquired her estate in 1927 from the British Treasury Solicitor after she died intestate. This acquisition included not only her writings, but also the estate of Henri Gaudier, with many of his works and papers. Ede drew extensively on the letters written by Gaudier to Brzeska, and her writings and other material, when he published "A Life of Gaudier-Brzeska" (London: W. Heinemann) in 1930; the 1931 and later editions are entitled "Savage Messiah". "Time Magazine" called his book a "sympathetic but perfectly impersonal...biography." The papers he used for this account are now in the archives of Cambridge University Library, the University of Essex, and the Musée des Beaux-Arts d'Orléans. In 2008 Sophie's unexpurgated writings were published.
Later years.
Brzeska moved to Wotton-under-Edge in Gloucestershire in 1916. Her mental state deteriorated and in 1922 she was committed to the County Mental Hospital where she was registered as Sophia Susanna Gaudier Brzeska.
Death.
Brzeska died intestate in the County Mental Hospital, Barnwood, Gloucestershire on 17 March 1925. 
She was often left out of accounts of Gaudier's life. "Savage Messiah", Ken Russell's 1972 film based on Ede's book, focuses on Sophie and Henri Gaudier's relationship giving them equal importance in shaping each other's lives. In the film she was played by Dorothy Tutin.
