Georgia O'Keeffe was one of the foundational figures of American modernism. A seminal woman artist, she rose to prominence in the early 20th century at the heart of the New York avant-garde circle that centred around Alfred Stieglitz, who would become O'Keeffe's husband. Many contemporary texts, as well as those written since, focus on their personal and professional relationship, and have re-hashed familiar cliches about O'Keeffe's work, particularly her best-known paintings of flowers. As this new book reveals, however, she was a complex and multi-faceted artist whose singular vision included landscapes, nature studies, still lifes and anthropological paintings, and who constantly experimented at the boundary between figuration and abstraction.
