Allan Eugene Updegraff (1883–1965) was an American-born novelist, poet, and editor. After he and his friend, Sinclair Lewis, dropped out of Yale during his junior year, he made a living working odd jobs, as well as writing stories for magazines and newspapers. In 1917 he had his first novel published. He moved to Paris in the mid 1920s, where he lived until his death in 1965. In addition to his six novels, he published poetry, short stories and essays, as well as having a short stint as a book reviewer. He was married twice: after a brief marriage to Edith Summers, which produced two children, he married freelance writer and fashion consultant Dora Loues Miller, who he remained married to for more than forty years, until his death in 1965.
