Claude Monet also known as Oscar-Claude Monet or Claude Oscar Monet (November 14, 1840 – December 5, 1926) was a founder of French impressionist painting, and the most consistent and prolific practitioner of the movement's philosophy, 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.
