Ayn Rand (IPA: /ˈaɪn ˈrænd/, February 2 [O.S. January 20] 1905 – March 6, 1982), born Alisa Zinov'yevna Rosenbaum (Russian: Алиса Зиновьевна Розенбаум), was a Russian-born American novelist and philosopher. She is widely known for her best-selling novels The Fountainhead and Atlas Shrugged, and for developing a philosophical system she called Objectivism.
She was an uncompromising advocate of rational individualism and laissez-faire capitalism, and vociferously opposed socialism, altruism, and other contemporary philosophical trends, as well as religion. Her influential and often controversial ideas have attracted both enthusiastic admirers and scathing denunciation.
