US-born Ellsworth Kelly trained at the Pratt Institute in Brooklyn for two years as a young man before he was conscripted to the army in 1943. After the war, he began his career as an artist in America and France. He studied first at the School of the Museum of Fine Arts in Boston then at the Ecole National Superieure Beaux-Arts in Paris, where he moved in 1948. Kelly worked as a painter, printmaker and sculptor and is most often associated with the minimalist and surrealist styles. His simple technique used bright, bold colours, lines and forms to convey its message.
