Best known as a novelist and member of the "Lost Generation" of American writers, Dos Passos (1896–1970) turned to writing history later in his career. His 1954 book The Head and Heart of Thomas Jefferson helped revived interest in our third President. Dos Passos served in World War I as an ambulance driver with his friend, the poet E.E. Cummings and in 1937, he returned to Spain with his friend Ernest Hemingway to cover the Spanish Civil War. During his distinguished career, Dos Passos wrote forty-two novels, as well as numerous poems, essays, and plays. His most widely read books were a 1925 novel about life in New York City, Manhattan Transfer, and the U.S.A. Trilogy, the first book of which appeared in 1930.
