Van Gogh worked for Goupil in London from 1873 to May 1875 and in Paris from that date until April 1876. Daily contact with works of art aroused his artistic sensibility, and he soon formed a taste for Rembrandt, Frans Hals, and other Dutch masters, although his preference was for two contemporary French painters, Jean-François Millet and Camille Corot, whose influence was to last throughout his life. Van Gogh disliked art dealing. Moreover, his approach to life darkened when his love was rejected by a London girl in 1874. His burning desire for human affection thwarted, he became increasingly solitary. He worked as a language teacher and lay preacher in England and, in 1877, worked for a bookseller in Dordrecht, Netherlands. Impelled by a longing to serve humanity, he envisaged entering the ministry and took up theology; however, he abandoned this project in 1878 for short-term training as an evangelist in Brussels. A conflict with authority ensued when he disputed the orthodox doctrinal approach. Failing to get an appointment after three months, he left to do missionary work among the impoverished population of the Borinage, a coal-mining region in southwestern Belgium. There, in the winter of 1879–80, he experienced the first great spiritual crisis of his life. Living among the poor, he gave away all his worldly goods in an impassioned moment; he was thereupon dismissed by church authorities for a too-literal interpretation of Christian teaching.
In 1892 Émile Bernard organised a small solo show of Van Gogh's paintings in Paris, and Julien Tanguy exhibited his Van Gogh paintings with several consigned from Johanna van Gogh-Bonger. In April 1894 the Durand-Rue Gallery in Paris agreed to take 10 paintings on consignment from Van Gogh's estate. In 1896, the Fauvist painter Henri Matisse, then an unknown art student, visited John Peter Russell on Belle Île off Brittany. Russell had been a close friend of Van Gogh; he introduced Matisse to the Dutchman's work, and gave him a Van Gogh drawing. Influenced by Van Gogh, Matisse abandoned his earth-coloured palette for bright colours.
