"The work of Rand, most of it published between the 1940s and 1960s, was very popular in the United States and gained a large and still active following. Rand developed her own school of philosophy called Objectivism, that centers on the principle of selfishness. In her novels and philosophical works, Rand advocates a form of rational and ethical egoism, and a political order based on laissezfaire capitalism. Her two novels, Fountainhead (1943) and Atlas Shrugged (1957) are lengthy portrayals of strong individuals who heroically and steadfastly pursue their lives according to Rand's philosophical principles."
