Thomas Stearns Eliot (September 26, 1888–January 4, 1965)was an American-born English poet, playwright, and literary critic, arguably the most important English-language poet of the 20th century. His first notable publication, The Love Song of J. Alfred Prufrock, begun in February 1910 and published in Chicago in June 1915, is regarded as a masterpiece of the modernist movement. It was followed by some of the best-known poems in the English language, including Gerontion (1920), The Waste Land (1922), The Hollow Men (1925), Ash Wednesday (1930), Old Possum's Book of Practical Cats (1939), and Four Quartets (1945). He is also known for his seven plays, particularly Murder in the Cathedral (1935) and The Cocktail Party (1949). He was awarded the Nobel Prize in Literature and the Order of Merit in 1948.
