Largely self-taught, Rothko was an American painter who became a leading exponent of a uniquely personal strain within the larger movement of abstract expressionism. By 1950, he was creating his so-called color-field paintings, works with large rectangles of color that express moods. In 1970, he committed suicide shortly after completing what some regard as his masterwork, a group of murals for a chapel in Houston, Texas.
