George Lichtheim (1912–1973) was a German-born intellectual whose works focused on the history and theory of socialism and Marxism. He defined himself as a socialist and stated in a 1964 letter to The New York Review of Books that "I am not a liberal and never have been. I find liberalism almost as boring as communism and have no wish to be drawn into an argument over which of these two antiquated creeds is less likely to advance us any further."
His work appeared in the Palestine Post, Commentary, Partisan Review, Dissent, the New Leader, Encounter, the Times Literary Supplement and The New York Review of Books. Additionally, he translated Gershom Scholem's Major Trends in Jewish Mysticism. His death was by suicide.
