Georgia O'Keeffe (1887-1986) was one of the most successful American artists of the 20th-century: her arresting paintings of enormous, intimately rendered flowers, desert landscapes and stark white cow skulls are seminal works of modern art. But behind O'Keeffe's bold work and celebrity was a woman misunderstood by even her most ardent admirers. When she was still unknown as an artist, O'Keeffe married Alfred Stieglitz, 23 years her senior. The relationship was physically and intellectually passionate, but Atieglitz was a man of the world. Driven to a nervous breakdown by Stieglitz's affair, O'Keefe relocated and redefined herself in New Mexico, where she created her unforgettable signature paintings. Through personal material - including interviews with Dorothy Norman, Stieglitz's longtime paramour - this biography offers an insight into O'Keefe's defining relationships and the effect of her husband's infidelity, and offers an honest portrayal of a life shrouded in myth.
