Georgia O'Keeffe has long been recognized as one of America's most adventurous early modernist artists. But critics often suggest that she became a revolutionary despite her American background, not because of it. Bram Dijkstra challenges that point of view. In this searching reappraisal of O'Keeffe's work, the distinguished cultural historian shows that her art was decisively shaped by the America in which she grew up. In doing so, he casts new light on the facts of O'Keeffe's remarkable life and offers incisive new readings of many of her most important paintings.
