Eugène Boudin
In 1856 Boudin met Claude Monet who spent several months working with Boudin in his studio. The two remained lifelong friends. Monet later said that Boudin had been a major influence on him, teaching him to paint outdoors. Camille Corot who was one of the greatest influences on Monet and the other Impressionists, gazed at Boudin's work and said "You are the master of the sky."
