Thomas Stearns "T. S." Eliot OM (September 26, 1888 – January 4, 1965) was a playwright, literary critic, and arguably the most important English-language poet of the 20th century. Although he was born an American he moved to the United Kingdom in 1914 (at age 25) and was naturalised as a British subject in 1927 at age 39. The poem that made his name, The Love Song of J. Alfred Prufrock—started in 1910 and published in Chicago in 1915—is regarded as a masterpiece of the modernist movement. He followed this with what have become some of the best-known poems in the English language, including Gerontion (1920), The Waste Land (1922), The Hollow Men (1925), Ash Wednesday (1930), and Four Quartets (1945). He is also known for his seven plays, particularly Murder in the Cathedral (1935). He was awarded the Nobel Prize in Literature in 1948.
