VICTOR SERGE (1890-1947) was born Victor Lvovich Kibalchich to Russian anti-tsarist exiles, impoverished intellectuals living "by chance" in Brussels. A precocious anarchist firebrand, young Victor was sentenced to five years in a French penitentiary in 1912. Expelled to Spain in 1917, he participated in an anarcho-syndicalist uprising before leaving to join the Revolution in Russia. Detained for more than a year in a French concentration camp, Serge arrived in St. Petersburg early in 1919 and joined the Bolsheviks, serving in the press services of the Communist International. An outspoken critic of Stalin, Serge was expelled from the Party and briefly arrested in 1928. Henceforth an "unperson," he completed three novels (Men in Prison, Birth of Our Power, and Conquered City) and a history (Year One of the Russian Revolution), all published in Paris. Arrested again in Russia and deported to Central Asia in 1933, he was allowed to leave the USSR in 1936 after international protests by militants and prominent writers like Andre Gide and Romain Rolland. Using his insider's knowledge, Serge published a stream of impassioned, documented exposes of Stalin's Moscow show trials and machinations in Spain, which went largely unheeded. Stateless, penniless, hounded by Stalinist agents, Serge lived in precarious exile in Brussels, Paris, Vichy France, and Mexico City, where he died in 1947. His classic Memoirs of a Revolutionary and his great last novels, Unforgiving Years and The Case of Comrade Tulayev (both available as NYRB Classics), were written "for the desk drawer" and published posthumously. Susan Sontag (1933-2004) was the author of four novels, The Benefactor, Death Kit, The Volcano Lover, and In America, which won the 2000 National Book Award for Fiction; a collection of stories, I, Etcetera; several plays, including Alice in Bed and Lady from the Sea; and seven works of nonfiction, among them Where the Stress Falls and Regarding the Pain of Others. Her books have been translated into thirty-two languages. In 2001, she was awarded the Jerusalem Prize for the body of her work; in 2003, she received the Prince of Asturias Prize for Literature and the Peace Prize of the German Book Trade.
