Claude Monet

Claude Monet (14 November 1840 – 5 December 1926) was a founder of French impressionist painting, and the most consistent and prolific practitioner of the movement's philosophy of expressing one's perceptions before nature, especially as applied to plein-air landscape painting. The term Impressionism is derived from the title of his painting Impression, Sunrise (Impression, soleil levant). [Source]
