Isaac Rosenfeld was a Jewish-American writer who became a prominent member of New York intellectual circles. Rosenfeld wrote one novel, which, according to literary critic Marck Shechner, "helped fashion a uniquely American voice by marrying the incisiveness of Mark Twain to the Russian melancholy of Dostoevsky," and many articles for The Nation, Partisan Review, and The New Republic. Some of those articles were posthumously published in a volume titled An Age of Enormity, and his short stories were later published as Alpha and Omega.
