Irving Louis Horowitz (September 25, 1929 – March 21, 2012) was an American sociologist, author, and college professor who wrote and lectured extensively in his field, and in his later years came to fear that it risked being seized by left-wing ideologues. He proposed a quantitative index for measuring a country's quality of life, and helped to popularize "Third World" as a term for the poorer nations of the Non-Aligned Movement. He was considered by many to be a neoconservative, although he maintained that he had no political adherence.[1]
