Georgia O'Keefe, one of the most renowned and honored American artists, died March 6, 1986, at the age of 98. O'Keefe is known for lush fantastical paintings of flowers, scenery and the American Southwest that led her to be dubbed the "mother of American modernism." Her famous large abstract-like close-up paintings of irises, lilies and other flowers have been considered erotic, and some feminist artists hailed her as a pioneer of "female iconography" - although O'Keefe denied such interpretations of her work.
