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. He is married to Nini Gilder, and has four children.
In the 1970s, Gilder established himself as a critic of feminism and government welfare policies, arguing that they eroded the "sexual constitution" that civilized and socialized men in the roles of fathers and providers. In the 1990s, he became an enthusiastic evangelist of technology and the Internet by several books and his newsletter, the Gilder Technology Report. He is also known as the chairman of George Gilder Fund Management, LLC.
