His uncle was a partner in the international firm of picture dealers Goupil and Co. and in 1869 van Gogh went to work in the branch at The Hague. In 1873 he was sent to the London branch and fell unsuccessfully in love with the daughter of the landlady. This was the first of several disastrous attempts to find happiness with a woman, and his unrequited passion affected him so badly that he was dismissed from his job. He returned to England in 1876 as an unpaid assistant at a school, and his experience of urban squalor awakened a religious zeal and a longing to serve his fellow men. His father was a Protestant pastor, and van Gogh first trained for the ministry, but he abandoned his studies in 1878 and went to work as a lay preacher among the impoverished miners of the grim Borinage district in Belgium. In his zeal he gave away his own worldly goods to the poor and was dismissed for his literal interpretation of Christ's teaching. He remained in the Borinage, suffering acute poverty and a spiritual crisis, until 1880, when he found that art was his vocation and the means by which he could bring consolation to humanity. From this time he worked at his new `mission' with single-minded frenzy, and although he often suffered from extreme poverty and undernourishment, his output in the ten remaining years of his life was prodigious: about 800 paintings and a similar number of drawings.
