John Roderigo Dos Passos, son of John Randolph Dos Passos, was an American novelist and artist.

He received a first-class education at The Choate School, in Connecticut, in 1907, under the name John Roderigo Madison. Later, he traveled with his tutor on a tour through France, England, Italy, Greece and the Middle East to study classical art, architecture and literature.

In 1912 he attended Harvard University and, after graduating in 1916, he traveled to Spain to continue his studies. In 1917 he volunteered for the Sanitary Squad Unit 60 of the Norton-Harjes Ambulance Corps, along with Edward Estlin Cummings and Robert Hillyer.

By the late summer of 1918, he had completed a draft of his first novel and, at the same time, he had to report for duty in the United States Army Medical Corps, in Pennsylvania.
When the war was over, he stayed in Paris, where the United States Army Overseas Education Commission allowed him to study anthropology at the Sorbonne.

Considered one of the Lost Generation writers, Dos Passos published his first novel in 1920, titled One Man's Initiation: 1917, followed by an antiwar story, Three Soldiers, which brought him considerable recognition. His 1925 novel about life in New York City, titled Manhattan Transfer was a success.

In 1937 he returned to Spain with Hemingway, but the views he had on the Communist movement had already begun to change, which sentenced the end of his friendship with Hemingway and Herbert Matthews.

In 1930 he published the first book of the U.S.A. trilogy, considered one of the most important of his works.

Only thirty years later would John Dos Passos be recognized for his significant contribution in the literary field when, in 1967, he was invited to Rome to accept the prestigious Antonio Feltrinelli Prize.

Between 1942 and 1945, Dos Passos worked as a journalist covering World War II and, in 1947, he was elected to the American Academy of Arts and Letters.
Tragedy struck when an automobile accident killed his wife, Katharine Smith, and cost him the sight in one eye. He remarried to Elizabeth Hamlyn Holdridge in 1949, with whom he had an only daughter, Lucy Dos Passos, born in 1950.

Over his long and successful carreer, Dos Passos wrote forty-two novels, as well as poems, essays and plays, and created more than four hundred pieces of art.

The John Dos Passos Prize is a literary award given annually by the Department of English and Modern Languages at Longwood University. The prize seeks to recognize "American creative writers who have produced a substantial body of significant publication that displays characteristics of John Dos Passos' writing: an intense and original exploration of specifically American themes, an experimental approach to form, and an interest in a wide range of human experiences."

As an artist, Dos Passos created his own cover art for his books, influenced by modernism in 1920s Paris. He died in Baltimore, Maryland. Spence's Point, his Virginia estate, was designated as a National Historic Landmark in 1971.
