In July 1869 Van Gogh's uncle Cent obtained a position for him at the art dealers Goupil & Cie in The Hague. After completing his training in 1873, he was transferred to Goupil's London branch at Southampton Street, and took lodgings at 87 Hackford Road, Stockwell. This was a happy time for Van Gogh; he was successful at work, and at 20 was earning more than his father. Theo's wife later remarked that this was the best year of Vincent's life. He became infatuated with his landlady's daughter, Eugénie Loyer, but was rejected after confessing his feelings; she was secretly engaged to a former lodger. He grew more isolated, and religiously fervent. His father and uncle arranged a transfer to Paris in 1875, where he became resentful of issues such as the degree to which the firm commodified art, and was dismissed a year later.
Born into an upper-middle-class family, Van Gogh drew as a child and was serious, quiet and thoughtful. As a young man he worked as an art dealer, often travelling, but became depressed after he was transferred to London. He turned to religion and spent time as a Protestant missionary in southern Belgium. He drifted in ill health and solitude before taking up painting in 1881, having moved back home with his parents. His younger brother Theo supported him financially, and the two kept up a long correspondence by letter. His early works, mostly still lifes and depictions of peasant labourers, contain few signs of the vivid colour that distinguished his later work. In 1886, he moved to Paris, where he met members of the avant-garde, including Émile Bernard and Paul Gauguin, who were reacting against the Impressionist sensibility. As his work developed he created a new approach to still lifes and local landscapes. His paintings grew brighter in colour as he developed a style that became fully realised during his stay in Arles in the south of France in 1888. During this period he broadened his subject matter to include series of olive trees, wheat fields and sunflowers.
Theo kept all of Vincent's letters to him; Vincent kept few of the letters he received. After both had died, Theo's widow Johanna arranged for the publication of some of their letters. A few appeared in 1906 and 1913; the majority were published in 1914. Vincent's letters are eloquent and expressive and have been described as having a "diary-like intimacy", and read in parts like autobiography. The translator Arnold Pomerans wrote that their publication adds a "fresh dimension to the understanding of Van Gogh's artistic achievement, an understanding granted us by virtually no other painter".
After Van Gogh's first exhibitions in the late 1880s, his reputation grew steadily among artists, art critics, dealers and collectors. In 1887 André Antoine hung Van Gogh's alongside works of Georges Seurat and Paul Signac, at the Théâtre Libre in Paris; some were acquired by Julien Tanguy. In 1889 his work was described in the journal Le Moderniste Illustré by Albert Aurier as characterised by "fire, intensity, sunshine". Ten paintings were shown at the Société des Artistes Indépendants, in Brussels in January 1890. French president Marie François Sadi Carnot was said to have been impressed by Van Gogh's work.
The same thing happened at the Church of Belgium: In the winter of 1878, van Gogh volunteered to move to an impoverished coal mine in the south of Belgium, a place where preachers were usually sent as punishment. He preached and ministered to the sick, and also drew pictures of the miners and their families, who called him "Christ of the Coal Mines."
By this time van Gogh was ready for such lessons, and the changes that his painting underwent in Paris between the spring of 1886 and February 1888 led to the creation of his personal idiom and style of brushwork. His palette at last became colourful, his vision less traditional, and his tonalities lighter, as may be seen in his first paintings of Montmartre. By the summer of 1887 he was painting in pure colours and using broken brushwork that is at times pointillistic. Finally, by the beginning of 1888, van Gogh’s Post-Impressionist style had crystallized, resulting in such masterpieces as Portrait of Père Tanguy and Self-Portrait in Front of the Easel, as well as in some landscapes of the Parisian suburbs.
