She is known for her fiction and for developing a philosophical system she named Objectivism. Born and educated in Russia, she moved to the United States in 1926. After two early novels that were initially unsuccessful and two Broadway plays, she achieved fame with her 1943 novel, The Fountainhead. In 1957, Rand published her best-selling work, the novel Atlas Shrugged.
