1887-1986. US painter, based mainly in New York and New Mexico, known for her large, semi-abstract studies of flowers and skulls. Her mature style stressed contours and subtle tonal transitions, and in paintings such as Black Iris 1926 (Metropolitan Museum of Art, New York) the subject is transformed into a powerful and erotic abstract image. In 1946 she settled in New Mexico, where the desert landscape inspired many of her paintings. She was married (1924-46) to photographer and art exhibitor Alfred Stieglitz, in whose gallery her work was first shown.
