1903-1970. Russian-born US painter, an Abstract Expressionist and a pioneer of Colour Field painting (abstract, dominated by areas of unmodulated, strong colour). Rothko produced several series of paintings in the 1950s and 1960s, including one at Harvard University; one in the Tate Gallery, London; and one for a chapel in Houston, Texas, 1967-69. He received his only training at New York City's Art Students League. During the 1930s he painted for the Federal Arts Project and, with Adolph Gottlieb, founded the expressionist group The Ten. After his suicide 1970, his estate, consisting primarily of a huge number of his paintings, became the subject of a long legal battle.
