Georgia O'Keeffe

Georgia Totto O'Keeffe was an American modernist painter and draftswoman whose career spanned seven decades and whose work remained largely independent of major art movements. Called the "Mother of American modernism", O'Keeffe gained international recognition for her meticulous paintings of natural forms, particularly flowers and desert-inspired landscapes, which were often drawn from and related to places and environments in which she lived.
