Louis Untermeyer (1885–1977) was an American poet, anthologist, critic, and editor. He was appointed the 14th Consultant in Poetry to the Library of Congress in 1961. Untermeyer was the author or editor of close to 100 books, from 1911 until his death. Many of them and his other memorabilia are preserved in a special section of the Lilly Library at Indiana University. Schools used his books Modern American Poetry and Modern British Poetry widely, often introducing college students to poetry beginning in 1919.
