Victor Serge: Victor Serge (1889-1947) is best known as a novelist – with two of his works recently republished by the New York Review of Books – and for his Memoirs of a Revolutionary. Originally a participant in the anarchist movement, Serge became a committed bolshevik upon arrival in Russia during 1919 and lent his considerable talents to the cause of spreading the revolution across Europe. An eloquent critic of tyranny no matter its form, Serge was a leading member of the Left Opposition in its struggle against Stalin, a cause which ultimately resulted in his exile from Russia.

Following the assassination of her husband Leon Trotsky in 1940, Sedova maintained her defense of internationalism and struggle against Stalinism and Fascism until her death.
