Oscar-Claude Monet (14 November 1840 – 5 December 1926) was a French painter and founder of Impressionism painting who is seen as a key precursor to modernism, especially in his attempts to paint nature as he perceived it. During his long career, he was the most consistent and prolific practitioner of Impressionism’s philosophy of expressing one’s perceptions of nature, especially as applied to plein air (outdoor) landscape painting.
