Henri Julien Félix Rousseau (French: [ɑ̃ʁi ʒyljɛ̃ feliks ʁuso]; 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 collector. Ridiculed during his lifetime by critics, he came to be recognised 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.
