Ludwig Heinrich Edler von Mises (German pronunciation: [ˈluːtvɪç fɔn ˈmiːzəs]; September 29, 1881 – October 10, 1973) was a philosopher, Austrian School economist, and classical liberal. He became a prominent figure in the Austrian School of economic thought and is best known for his work on praxeology. Fearing a Nazi takeover of Europe, Mises emigrated to the United States in 1940. Mises had a significant influence on the libertarian movement in the United States in the mid-20th century.

Ludwig von Mises was born to wealthy Jewish parents in the city of Lemberg, in Galicia, Austria-Hungary (now Lviv in Ukraine). The family of his father Arthur Edler von Mises had been elevated to the Austrian nobility in the 19th century, and was involved in building and financing railroads. Ludwig's mother, Adele (née Landau), was a niece of Dr. Joachim Landau, a Liberal Party deputy to the Austrian Parliament. Arthur was stationed there as a construction engineer with Czernowitz railway company. At the age of twelve Ludwig spoke fluent Yiddish, German, Polish, and French, read Latin, and could understand Ukrainian. Mises was the older brother of the famous applied physicist Richard von Mises, a member of the Vienna Circle. Another brother, Karl von Mises, died as a child from scarlet fever.^{[citation needed]} When Ludwig and Richard were children, his family moved back to their ancestral home of Vienna.

Ayn Rand ( /ˈaɪn ˈrænd/; born Alisa Zinov'yevna Rosenbaum, February 2 [O.S. January 20] 1905 – March 6, 1982) was a Russian-American novelist, philosopher, playwright, and screenwriter. She is known for her two best-selling novels The Fountainhead and Atlas Shrugged and for developing a philosophical system she called Objectivism.

Born and educated in Russia, Rand moved to the United States in 1926. She worked as a screenwriter in Hollywood and had a play produced on Broadway in 1935–1936. After two initially unsuccessful early novels, she achieved fame with her 1943 novel The Fountainhead. In 1957, she published her best-known work, the philosophical novel Atlas Shrugged. Afterward she turned to nonfiction to promote her philosophy, publishing her own magazines and releasing several collections of essays until her death in 1982.

Rand advocated reason as the only means of acquiring knowledge and rejected all forms of faith and religion. She supported rational and ethical egoism, and rejected ethical altruism. In politics, she condemned the initiation of force as immoral and opposed all forms of collectivism and statism, instead supporting laissez-faire capitalism, which she believed was the only social system that protected individual rights. She promoted romantic realism in art. She was sharply critical of the philosophers and philosophical traditions known to her besides Aristotle.
