(1840–1926), French painter. A founding member of the impressionists (his painting Impression: Sunrise [1872] gave the movement its name), his fascination with the play of light on objects led him to produce series of single subjects painted at different times of day and under different weather conditions, such as the Haystacks series (1890–91) and Rouen Cathedral (1892–95). Among his most famous paintings are the Waterlilies series, which he began in 1899 and which occupied him for the rest of his life.
