Allan David Bloom (September 14, 1930 - October 7, 1992) was an American philosopher, classicist, and academician. He studied under David Grene, Leo Strauss, Richard McKeon, and Alexandre Kojeve. He subsequently taught at Cornell University, the University of Toronto, Yale University, Ecole Normale Superieure of Paris, and the University of Chicago. Bloom championed the idea of Great Books education and became famous for his criticism of contemporary American higher education, with his views being expressed in his bestselling 1987 book, The Closing of the American Mind.

Bloom studied and taught in Paris (1953-55) at the Ecole Normale Superieure, and Germany (1957). Upon returning to the United States in 1955, he taught adult education students at the University of Chicago with his friend Werner J. Dannhauser, author of Nietzsche's View of Socrates. Bloom went on to teach at Yale from 1960 to 1963, at Cornell until 1970, and at the University of Toronto until 1979, when he returned to the University of Chicago. Among Bloom's former students are prominent journalists, government officials and political scientists such as Francis Fukuyama, Robert Kraynak, Pierre Hassner, Clifford Orwin, Janet Ajzenstat, John Ibbitson, and John Milligan-Whyte.  In 1963, as a Professor at Cornell, Allan Bloom served as a faculty member of the Cornell Branch of the Telluride Association, an organization focused on intellectual development and self-governance. The students received free room and board in the Telluride House on the Cornell University campus and assumed the management of the house themselves. While living at the house, Bloom befriended former U.S. Secretary of Labor Frances Perkins. Bloom's first book was a collection of three essays on Shakespeare's plays, Shakespeare's Politics; it included an essay from Harry V. Jaffa. He translated and commented upon Rousseau's "Letter to M. D'Alembert on the Theater", bringing it into dialogue with Plato's Republic. In 1968, he published his most significant work of philosophical translation and interpretation, a translation of Plato's Republic. Bloom strove to achieve "translation... for the serious student". The preface opens on page xi with the statement, "this is intended to be a literal translation". Although the translation is not universally accepted, Bloom said he always conceptualized the translator's role as a matchmaker between readers and the texts he translated. He repeated this effort as a professor of political science at the University of Toronto in 1978, translating Jean-Jacques Rousseau's Emile. Among other publications during his years of teaching was a reading of Swift's Gulliver's Travels, titled "Giants and Dwarfs"; it became the title for a collection of essays on, among others, Raymond Aron, Alexandre Kojeve, Leo Strauss, and liberal philosopher John Rawls. Bloom was an editor for the scholarly journal Political Theory as well as a contributor to History of Political Philosophy (edited by Joseph Cropsey and Leo Strauss).  After returning to Chicago, he befriended and taught courses with Saul Bellow. In 1987 Bellow wrote the Preface to The Closing of the American Mind.  Bloom's last book, which he dictated while in the hospital dying, and which was published posthumously, was Love and Friendship, an offering of interpretations on the meaning of love. There is an ongoing controversy over Bloom's semi-closeted homosexuality, possibly culminating--as in Saul Bellow's thinly fictionalized account in Ravelstein--in his death in 1992 from AIDS. Bloom's friends do not deny his homosexuality, but whether he actually died of AIDS remains disputed.
