Portrait of Henri Rousseau

Wikipedia: Henri Julien Félix Rousseau (French: [ɑ̃ʁi ʒyljɛ̃ feliks ʁuso]; 21 May 1844 – 2 September 1910)[1] was a French post-impressionist painter in the Naïve or Primitive manner.[2][3] He was also known as Le Douanier (the customs officer), a humorous description of his occupation as a toll and tax collector.[1] He started painting seriously in his early forties; by age 49, he retired from his job to work on his art full-time.[4]

Ridiculed during his lifetime by critics, he came to be recognized as a self-taught genius whose works are of high artistic quality.[5][6] Rousseau's work exerted an extensive influence on several generations of avant-garde artists.[4]
