Theo (1857–1891) was the younger brother of Vincent van Gogh who supported his brother both financially and emotionally. Theo introduced Vincent to the Impressionists working in Paris at the time, and the two wrote regular letters to each other during their lifetimes. Besides his support of his brother, Theo van Gogh was also an important art dealer, first working in Brussels and later in Paris, where he bought and exhibited paintings by Impressionist artists such as Claude Monet and Camille Pissarro. He also helped to sell the work of Paul Gauguin, who was also a friend of Vincent’s. Although Theo tried to sell his brother’s work in Paris, he did not meet much success. He died six months after Vincent at the age of thirty-three.
