From syndicalism through the Comintern to the Fourth International: a French internationalist across a century of revolution
Lenin described Rosmer as "a man who knows how to keep his mouth shut in five or six languages." — quoted in Philippe Robrieux's internal history of the French Communist Party
American-born French revolutionary syndicalist and a key figure in the Comintern leadership. With Pierre Monatte he published La Vie ouvrière and organised anti-war internationalism; he spent seventeen months in Moscow helping found the Red International of Labour Unions (Profintern). A Political Bureau member of the French Communist Party, he was expelled in 1924 for defending Trotsky, thereafter committing to the Left Opposition and Trotskyism. In 1938 he hosted the founding conference of the Fourth International at his home in Périgny. In his later years he signed the Manifesto of 121 against the Algerian War and wrote the classic memoir Lenin's Moscow.
