Bertram David "Bert" Wolfe (1896–1977) was an American scholar and former communist best known for biographical studies of Vladimir Lenin, Joseph Stalin, Leon Trotsky, and Diego Rivera.
Bertram Wolfe was born January 19, 1896 in Brooklyn, New York. His mother was a native-born American and his father was an ethnic Jewish immigrant from Germany who had arrived in the United States as a boy of 13.
Wolfe studied to teach English literature and writing and received degrees from the College of the City of New York, Columbia University, and the University of Mexico.
Wolfe was active with the Socialist Party of America in his youth and was an active participant in the Left Wing Section which emerged in 1919. Wolfe attended the June 1919 National Conference of the Left Wing and was elected by that body to its nine-member National Council. He helped draft the manifesto of that organization, together with Louis C. Fraina and John Reed.
In 1919 Wolfe became a founding member of the Communist Party of America (CPA). Together with Maximilian Cohen, Wolfe was responsible for The Communist World, the CPA's first newspaper in New York City.
During the period of repression of leading Communists in New York conducted by the Lusk Committee, Wolfe fled to California. In 1920 he became a member of the San Francisco Cooks' Union. He also edited a left wing trade union paper called Labor Unity from 1920 to 1922. Wolfe was a delegate to the ill-fated August 1922 convention of the underground CPA held in Bridgman, Michigan, for which he was indicted under Michigan's "criminal syndicalism" law.
