During the Franco-Prussian War from 1870-1871, Pissarro lived in England and made a study of English art, particularly the landscapes of Joseph Mallord William Turner, which caused him to lighten his palette and formulate a technique of applying strokes of bright color to the canvas to create luminous effects. He never, however, abandoned an underlying sense of solid form and contour. Also, while in London, Pissarro met Paul Durand-Ruel, the Parisian dealer who would become an ardent supporter of Pissarro and his fellow Impressionists.
After his return to France, Camille Pissarro married Julie Vellay, a maid in his mother's household. Of their eight children together, one died at birth and a daughter died when nine. The surviving children all painted, and Lucien, the oldest son, became a follower of William Morris.
Pissarro settled in Pontoise, where he often received young artists seeking advice, including Paul Cézanne and Paul Gauguin.
Discouraged by their attempts to pass the critical scrutiny of the Salon juries, Pissarro joined Monet in 1874 for a project to organize independent exhibitions. Renoir, Sisley, Béliard, Guillaumin, Degas, Cézanne and Berthe Morisot were among those whose works were exhibited.
Pissarro and his fellows were met with severe opposition from critics. In a community that valued technical detail and photographic realism and expected the artist to idealize the subject, their work was seen as an absurdity and articles covering the exhibition coined the term "impressionist" as an insult. Artistic acceptance was slow to come, barely achieved in Pissarro's lifetime.
Through years of poverty and despair the impressionists laboured to gain a place in the world. Carrying their banner, Pissarro remained true to his vision. He experimented with theories of art; studied the effects of light, climate, and the seasons and adopted new techniques. From these he fused a style that remained his own, within the larger style of Impressionism.
In the 1880s, again becoming discouraged with his work, he experimented with pointillism. This new style, however, proved unpopular with collectors and dealers, and he returned to a freer impressionist style.
Pissarro was especially regarded as a teacher; he became the centre of a group of painters - Renoir, Monet, Degas, Cézanne - who respected his art and turned to him for inspiration. He was revered by the Post-Impressionists, including Cézanne and Gauguin, who both referred to him toward the end of their own careers as their “master.” Pissarro did much to bring about the achievements of the Impressionists and he lived long enough to witness the start of the Impressionists’ fame and influence.
In his 74th year, Camille Pissarro had finally attained the respectability that had eluded him most of his life. His paintings were starting to fetch high prices at auction and a new generation of artists admired his work.
In the last years of his life, Pissarro experienced eye trouble, which forced him to abandon outdoor painting. He continued, however, to work in his studio until his death in Paris on November 13, 1903. He died of blood poisoning and was survived by sons Lucien, Georges, Félix, Ludovic-Rodolphe, Paul Emile; and daughter, Jeanne.
Known as the Father of Impressionism, Pissarro painted rural and urban French life, particularly landscapes in and around Pontoise, as well as scenes from Montmartre and street scenes in Paris, Le Havre, and London. He was a painter of sunshine and the scintillating play of light and his mature work also displayed an empathy for peasants and labourers.
