Henri Julien Félix Rousseau was a French post-impressionist painter in the Naïve or Primitive manner. He was also known as Le Douanier, a humorous description of his occupation as a toll and tax collector. He started painting seriously in his early forties; by age 49, he retired from his job to work on his art full-time.

Post-Impressionism was a predominantly French art movement that developed roughly between 1886 and 1905, from the last Impressionist exhibition to the birth of Fauvism. Post-Impressionism emerged as a reaction against Impressionists' concern for the naturalistic depiction of light and colour. Its broad emphasis on abstract qualities or symbolic content means Post-Impressionism encompasses Les Nabis, Neo-Impressionism, Symbolism, Cloisonnism, the Pont-Aven School, and Synthetism, along with some later Impressionists' work. The movement's principal artists were Paul Cézanne, Paul Gauguin, Vincent van Gogh and Georges Seurat.
