John Roderigo Dos Passos (January 14, 1896 – September 28, 1970) was an American novelist, most notable for his U.S.A. trilogy. He was a descendant of the Lee Family of Virginia.
Born in Chicago, Dos Passos graduated from Harvard College in 1916. He traveled widely as a young man, visiting Europe and southwest Asia, where he learned about literature, art, and architecture. During World War I, he was an ambulance driver for the American Volunteer Motor Ambulance Corps in Paris and Italy, before joining the United States Army Medical Corps as a private.
In 1920, his first novel, One Man's Initiation: 1917, was published, and in 1925, his novel Manhattan Transfer became a commercial success. His U.S.A. trilogy, which consists of the novels The 42nd Parallel (1930), 1919 (1932), and The Big Money (1936), was ranked by the Modern Library in 1998 as 23rd of the 100 best English-language novels of the 20th century. Written in experimental, non-linear form, the trilogy blends elements of biography and news reports to paint a landscape of early 20th-century American culture.
Beyond his writing, Dos Passos is known for his shift in political views.
