The major difference between novel and real life was in the chronology of Cameron's relation with his protégé Howard Roark, the novel's hero, who eventually goes on to redeem his vision. That Roark's uncompromising individualism and his innovative organic style in architecture were drawn from the life and work of Frank Lloyd Wright is clear from Rand's journal notes, her correspondence, and various contemporary accounts. In the novel, however, the 23-year-old Roark, a generation younger than the real-life Wright, becomes Cameron's protégé in the early 1920s, when Sullivan was long in decline.
