Theodorus van Gogh (1 May 1857 – 25 January 1891) was a Dutch art dealer. He was the younger brother of Vincent van Gogh, and Theo’s unfailing financial and emotional support allowed his brother to devote himself entirely to painting. Theo died at the age of 33, six months after his brother died at the age of 37.
Theo admired his elder brother Vincent for his whole life, but communicating with him proved to be difficult, even before Vincent opted to follow his artistic vocation. Theo was often concerned about Vincent’s mental condition and he was amongst the few who understood his brother. He also helped Vincent pursue his life as an artist through his unwavering emotional support and love. The majority of Theo’s letters and communications with Vincent are filled with praise and encouragement. Vincent would send Theo sketches and ideas for paintings, along with accounts of his day to day experiences, to the delight and eager attention of Theo.
While Theo is best known for being the brother of Vincent van Gogh, he also played a vital role in the introduction of contemporary Dutch and French art to the public. Theo was instrumental in the popularity of Impressionist artists such as Claude Monet and Edgar Degas by persuading his employers, Goupil & Cie, to exhibit and buy their works.
