Did Vincent van Gogh achieve critical fame during his lifetime?

Van Gogh's work was treated largely with indifference during his lifetime. Famously, he only sold one painting. And it was only in the years following his death that he, along with other post-impressionists, started to achieve popular and critical acclaim. With the passage of time, Van Gogh's paintings have become part of the mainstream. Yet it is important to remember how completely radical his work and that of other post-impressionists seemed at the time.
The artists of this school were concerned to do away with a naturalistic approach to painting, instead turning their attention to symbolism and structure. They also believed that color was independent of form; this allowed them to explore color in greater depth now that it could be studied in its own right, separate from formal constraints. Van Gogh epitomizes this new and radical approach in his own work, particularly in his deep explorations of the color yellow as seen in his paintings of sunflowers and wheat fields.
To many people at the time, Van Gogh's abandonment of the accepted standards of painting seemed shocking, and so his genius as an artist went largely unappreciated.

Vincent van Gogh did not receive any type of notoriety or acclamation during his lifetime. He actually did not sell one painting, which is very ironic since now, more than a century after his death, his paintings are worth millions and millions of dollars. Van Gogh's brother Theo was his art dealer, and although Theo tried mightily to interest art dealers in his brother's works, he was unsuccessful in doing so. Nevertheless, during Vincent's lifetime, he received financial and emotional support from Theo.
The relationship between the two brothers has become one of the most well-known attachments in art history because of the lifelong unbreakable bond existing between Vincent and Theo.
Other artists that lived during his time. Did receive a great deal of same, including his friend Paul Gauguin. Another example of an artist being very popular and commercially successful during his lifetime was Pierre Auguste Renoir, who enjoyed a great deal of success from wealthy French art lovers who supported his work by buying and exhibiting many of his paintings.
