(b. 1841, Paris, d. 1927, Orly)
French painter and lithographer. He grew up in Moulins, but at 16 he returned to Paris to find work. Despite the opposition of his working-class family, he prepared for an artistic career while he supported himself in municipal jobs. He started drawing classes and then enrolled in the Académie Suisse, where he met Cézanne and Camille Pissarro. Guillaumin began his career as an avant-garde artist by exhibiting with them at the Salon des Refusés in 1863. He was also active in the Manet circle at the Café Guerbois, from which Impressionism developed.
He participated in six of the eight Impressionist exhibitions: 1874, 1877, 1880, 1881, 1882 and 1886. In 1886 he became a friend of Vincent van Gogh whose brother, Theo sold some of his works. He was finally able to quit his government job and concentrate on painting full-time in 1891, when he won 100,000 francs in the state lottery.
Noted for their intense colours, Guillamin's paintings are represented in major museums around the world. He is best remembered for his landscapes.
