George Franklin Gilder (born November 29, 1939) is an American investor, writer, economist, techno-utopian advocate, and co-founder of the Discovery Institute. His 1981 international bestseller Wealth and Poverty advanced a practical and moral case for supply-side economics and capitalism during the early months of the Reagan administration and made him Ronald Reagan's most quoted living author. In 2013 he published Knowledge and Power: The Information Theory of Capitalism and How It is Revolutionizing Our World, which reformulated economics in terms of the information theory of Alan Turing and Claude Shannon. Married to Nini Gilder, he has four children.
