Overview
Theodorus "Theo" van Gogh (1 May 1857 – 25 January 1891) was a Dutch art dealer remembered chiefly for his close partnership with his brother, the painter Vincent van Gogh. Working in the late 19th-century European art market, Theo combined a professional career as a dealer with sustained financial and emotional support for his brother. His correspondence with Vincent is one of the central documentary sources for the artist's life and work.
Career and influence
Theo worked in the commercial art trade in Europe, where dealers acted as intermediaries between artists, collectors and exhibitions. He specialized in contemporary painting of his day and was part of the network that introduced and promoted newer tendencies in French and Dutch art. While not primarily a public champion of radical aesthetics, his position enabled him to advise, purchase and exhibit works and to channel information and material support to artists he believed in.
Relationship with Vincent
Theo's relationship with his brother was practical as well as intimate. He provided money, painting materials and contacts, and the two exchanged a long series of letters that reveal Vincent’s ideas, ambitions and struggles. Those letters later became essential to understanding Vincent’s intentions and artistic development; many were preserved and published by Theo’s widow.
Family and legacy
Theo married Johanna Bonger, who played a decisive role after both brothers’ deaths in organizing and promoting Vincent’s work. Their son, Vincent Willem, continued the family’s efforts to safeguard and display the collection. The van Gogh correspondence and the archives assembled by Theo and his family remain fundamental resources for scholars and the public. For further archival references see archival sources.
