Born in 1939 in New York City, Mr. Gilder attended Exeter Academy and Harvard University. At Harvard, he studied under Henry Kissinger and helped found Advance, a journal of political thought, which he edited and helped to re-establish in Washington, DC after his graduation in 1962. During this period he co-authored (with Bruce Chapman) The Party That Lost Its Head. He later returned to Harvard as a fellow at the Kennedy Institute of Politics and editor of the Ripon Forum. In the 1960s Mr. Gilder also served as a speechwriter for several prominent official and candidates, including Nelson Rockefeller, George Romney, and Richard Nixon. In the 1970s, as an independent researcher and writer, Mr. Gilder began an excursion into the causes of poverty, which resulted in his books Men and Marriage (1972) and Visible Man (1978); and hence, of wealth, which led to his best-selling Wealth and Poverty (1981).
