Ayn Rand's philosophical novels The Fountainhead and Atlas Shrugged made her the most controversial author of her age. Her works have drawn millions of readers and continue to sell at a breathtaking pace. Their impact on American culture runs from libertarian politics to the self-esteem movement in psychology to the rugged individualism of Silicon Valley and the Internet. Rand also launched a movement of intellectuals committed to her philosophy of Objectivism. While it has grown dramatically since Rand's death in 1982, however, the Objectivist movement has also fractured into rival camps whose differences over doctrine and strategy are compounded by competition for leadership and bitter accusations of heresy.
