Claude Monet (French pronunciation: ) (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).
Claude Monet was born on 14 November 1840 on the 5th floor of 45 rue Laffitte, in the 9th arrondissement of Paris. He was the second son of Claude Adolphe Monet and Louise Justine Aubrée Monet, both of them second-generation Parisians. On 20 May 1841, he was baptized in the local parish church, Notre-Dame-de-Lorette, as Oscar-Claude, but his parents called him simply Oscar. In 1845, his family moved to Le Havre in Normandy. His father wanted him to go into the family grocery business, but Monet wanted to become an artist. His mother was a singer.
On 1 April 1851, Monet entered Le Havre secondary school of the arts. Locals knew him well for his charcoal caricatures, which he would sell for ten to twenty francs. Monet also undertook his first drawing lessons from Jacques-François Ochard, a former student of Jacques-Louis David. On the beaches of Normandy in about 1856/1857, he met fellow artist Eugène Boudin, who became his mentor and taught him to use oil paints. Boudin taught Monet "en plein air" (outdoor) techniques for painting. Both received the influence of Johan Barthold Jongkind.
