During her long and distinguished career, which developed to its highest level in the deserts of the American Southwest, Georgia O?Keeffe pioneered an artistic style that dominated the art of twentieth-century America. Unique in its organic, abstract expression, her vision and passion identify her as a lifelong master of modern art. With crystalline clarity and a vivid sensuous feeling for both objects and landscapes, O?Keeffe painted life studies that were to distinguish her as an original and adventurous painter. Her studies of flowers, bones, cityscapes, and southwestern landscapes have become some of the most recognizable images in modern art.
