Monet and Renoir painted together.
Oscar-Claude Monet was a French painter, a founder of French Impressionist painting and the most consistent practitioner of the movement's philosophy of expressing one's views before nature, particularly as applied to plein air landscape painting.
Pierre-Auguste Renoir was a French artist who became a leading painter in the development of the Impressionist style.
Both Monet and Renoir were very good friends.
