Originally from Canada, Agnes Martin (1912-2004) moved to the U.S. in 1931. Martin lived in Taos, New Mexico from 1954 to 1957, and then moved to New York, where she established her name as an important minimalist painter. Her work differed conceptually from the minimalist movement in that it was anti-intellectual and intensely spiritual, and her grids represented meditative reflections on Taoism. For years, Martin worked only in black, white, and (occasionally) brown.  Her devotees consider her a visionary — an artist possessed of perceptive powers that have transformed her style into a heightened visual experience. Martin returned to New Mexico in 1967 where she lived and worked throughout her life.
