Henri Julien Félix Rousseau (Le Douanier) (b. 1844 d. 1910), simply known as Henri Rousseau, was a French post-impressionist painter of the Naïve or Primitive style. He was additionally regarded as 'Le Douanier', a humorous name for his occupation as a toll and tax collector. Though ridiculed during his lifetime, he posthumously gained recognition as a self-taught genius whose works are of high artistic quality. His work has been a significant influence on later generations of avant-garde artists.
