Robert Nozick (November 16, 1938 – January 23, 2002) was an American philosopher and Pellegrino University Professor at Harvard University. Nozick, schooled at Columbia, Oxford and Princeton, was a prominent American political philosopher in the 1970s and 1980s. He did additional but less influential work in such subjects as decision theory and epistemology. His Anarchy, State, and Utopia (1974) was a libertarian answer to John Rawls' A Theory of Justice, published in 1971. He was born in Brooklyn, the son of a Jewish entrepreneur from Russia. He was married to the American poet Gjertrud Schnackenberg. Nozick died in 2002 after a prolonged struggle with cancer. His remains are interred at Mount Auburn Cemetery in Cambridge, Massachusetts.
