Marxist historian of Trotsky's definitive biography, who coined the 'non-Jewish Jew'

"I still believe!" — indicting the Cold War and the Vietnam War before thousands of students at the 1965 Berkeley teach-in

Born into a Polish Jewish family, a prodigy in Hasidic scripture who became an atheist in his teens. Joined the Polish Communist Party in 1927; co-founded its first anti-Stalinist group and was expelled in 1932. Exiled to London in 1939. His Stalin: A Political Biography (1949) made him a world authority. Drawing on the Harvard Trotsky Archives, his three-volume life of Trotsky is widely regarded as among the greatest political biographies. A mentor to the 1960s New Left, he died suddenly in Rome in 1967.
