Henri Julien Félix Rousseau; 21 May 1844 – 2 September 1910) was a French post-impressionist painter in the Naïve or Primitive manner. He was also known as Le Douanier (the customs officer), a humorous description of his occupation as a toll and taxcollector. He started painting seriously in his early forties; by age 49, he retired from his job to work on his art full-time.
Ridiculed during his lifetime by critics, he came to be recognized as a self-taught genius whose works are of high artistic quality. Rousseau’s work exerted an extensive influence on several generations of avant-garde artists.
