Art dealer and brother of Vincent van Gogh. Theo van Gogh was an influential Dutch art dealer. He worked for the Parisian company Goupil & Cie. At first; this was at the branch in The Hague. This shop had been founded by his uncle Vincent ("Cent") van Gogh (1820-1888), who afterward became a partner of Goupil. On January 1st, 1873, Theo was transferred to the branch in Brussels, in June, to the one in London. For his brother, with whom he kept a regular correspondence since 1872, he arranged that in November 1873, Vincent got a job in The Hague. Theo soon became a successful art dealer and was promoted to headquarters in Paris. From 1880 he sent Vincent monthly painting material and an allowance. In 1886 he invited him to move in with him in Paris. Meanwhile, the firm had been sold to a son-in-law of Goupil and was now called "Boussod, Valadon et Cie." Theo introduced his brother to many famous painters, such as Paul Gauguin, Paul Cézanne, Henri de Toulouse-Lautrec, Henri Rousseau Camille Pissarro, and Georges Seurat. In 1888 he persuaded Gauguin to move in with Vincent, who was now living in Arles. The following year, he married Jo Bonger (1862-1925). They had one son, Vincent Willem van Gogh (1890-1978). On June 8th, 1890, the young couple visited Vincent, who had settled in Auvers-sur-Oise, near Paris. By that time, Theo considered possibly starting a business of his own. A month later, Vincent made a not-immediately-successful suicide attempt. Two days later, he died in the presence of Theo. The latter began to suffer from a deep depression. He was taken into a psychiatric hospital, first in Auteuil, but on November 18th in his native country. After two months, he died, probably as a result of syphilis and at the age of 33 years. He was buried at the Eerste Algemeene Begraafplaats Soestbergen, in Utrecht. In 1914 his mortal remains were transferred to Auvers-sur-Oise, where he was buried beside his brother. Thanks to his son V.W. van Gogh, the Van Gogh Museum in Amsterdam emerged. It was opened in 1973.
