Uncredited photograph of Pissarro, circa 1900. Camille Pissarro ( July 10 1830 - November 13, 1903) was a Danish-French Impressionist and Neo-Impressionist painter. His importance resides in his contributions to both Impressionism and Post-Impressionism. Pissarro studied from great forerunners, including Gustave Courbet and Jean-Baptiste-Camille Corot. He later studied and worked alongside Georges Seurat and Paul Signac when he took on the Neo-Impressionist style at the age of 54. In 1873 he helped establish a collective society of fifteen aspiring artists, becoming the pivotal figure in holding the group together and encouraging the other members. Pissarro is the only artist to have shown his work at all eight Paris Impressionist exhibitions, from 1874 to 1886. He acted as a father figure not only to the Impressionists, but to all four of the major Post-Impressionists, including Georges Seurat, Paul C矇zanne, Vincent van Gogh and Paul Gauguin. In his older age Pissarro suffered from a recurring eye infection that prevented him from working outdoors except in warm weather. As a result of this disability, he began painting outdoor scenes while sitting by the window of hotel rooms. He died in Paris in 1903 at th age of 73.
