John Dos Passos (1896–1970) was born in Chicago and graduated from Harvard in 1916. His service as an ambulance driver in Europe at the end of World War I led him to write Three Soldiers in 1919, the first in a series of works that established him as one of the most prolific, inventive, and influential American writers of the twentieth century.

Townsend Ludington, volume editor, is Cary C. Boshamer Professor of English and American Studies at the University of North Carolina and author of John Dos Passos: A Twentieth Century Odyssey.
