Thomas Stearns Eliot (September 26, 1888 - January 4, 1965) was an American-British poet, essayist and playwright. He is considered to be one of the 20th century's greatest poets, as well as a central figure in English-language Modernist poetry. His use of language, writing style, and verse structure reinvigorated English poetry. He is also noted for his critical essays, which often re-evaluated long-held cultural beliefs.
