John Dos PassosLike Sinclair Lewis, John Dos Passos began as a left-wing radical but moved to the right as he aged. Dos Passos wrote realistically, in line with the doctrine of socialist realism. His best work achieves a scientific objectivism and almost documentary effect. Dos Passos developed an experimental collage technique for his masterwork U.S.A., consisting of The 42nd Parallel (1930), 1919 (1932), and The Big Money (1936). This sprawling collection covers the social history of the United States from 1900 to 1930 and exposes the moral corruption of materialistic American society through the lives of its characters.
Dos Passos's new techniques included "newsreel" sections taken from contemporary headlines, popular songs, and advertisements, as well as "biographies" briefly setting forth the lives of important Americans of the period, such as inventor Thomas Edison, labor organizer Eugene Debs, film star Rudolph Valentino, financier J.P. Morgan, and sociologist Thorstein Veblen. Both the newsreels and biographies lend Dos Passos's novels a documentary value; a third technique, the "camera eye," consists of stream of consciousness prose poems that offer a subjective response to the events described in the books.
