Charles Edward Russell was a major intellectual and political figure of the late nineteenth- and early twentieth-century United States. As a very well-known American radical, he published many books on the US economy, the condition of workers, social issues, and other subjects. He was an active member of the American socialist movement before 1917, but when the US entered the war in 1917 he moved to support the US war effort, something many radicals had still opposed. When President Woodrow Wilson was preparing a special delegation to Russia in the summer of 1917, he added Russell to the delegation in an effort to include a radical at a time when the Russian Provisional Government was increasingly socialist.
