born March 22, 1912, Maklin, Sask., Can.
Canadian-born U.S. painter.
She moved to the U.S. in 1932 and became a U.S. citizen in 1940. She studied at Columbia Teachers College and taught at the University of New Mexico. She had her first solo exhibition in 1958. A prominent exponent of geometric abstraction, for her, a gray grid of intersecting penciled lines became the ultimate geometric composition. In the 1970s she produced printed equivalents of her paintings; a notable series of silkscreens, On a Clear Day (1973), were produced after her mathematically annotated sketches. Her work has been connected with Abstract Expressionism and Minimalism .
