When Random House proposed that I write the first full-length biography of Rockefeller since Allan Nevins’s in the 1950s, I frankly balked, convinced that the subject had been exhausted by writers too eager to capitalize on his fame. How could one write about a man who made such a fetish of secrecy? In the existing literature, he came across as a gifted automaton at best, a malevolent machine at worst. I couldn’t tell whether he was a hollow man, deadened by the pursuit of money, or someone of great depth and force but with eerie self-control.
