Question: Which British writer considered "one of the twentieth century's major poets" was introduced in the United States through the literary magazine "The Little Review"?
Context: The obscenity trial over the publication of James Joyce’s "Ulysses" in "The Little Review", an American literary magazine, occurred in 1921 and effectively banned publication of Joyce's novel in the United States.  After "The Little Review" published the "Nausicaa" episode of "Ulysses" in the 1920 July–August issue of the magazine, the New York Society for the Suppression of Vice instigated obscenity charges against "Little Review" editors Margaret Caroline Anderson and Jane Heap.  The editors were found guilty under laws associated with the Comstock Act of 1873, which made it illegal to circulate materials deemed obscene in the U.S. mail.  Anderson and Heap incurred a $100 fine, and were forced to cease publishing "Ulysses" in "The Little Review". The Little Review Gallery was a small Modern Art gallery associated with the magazine American literary magazine "The Little Review".  The gallery was owned and operated from 1924 to 1927 by Jane Heap, the acting editor of "The Little Review" at that time.  The gallery was primarily devoted to Constructivism, Dadaism, and Machine-inspired art. The Fugitives were a group of poets and literary scholars who came together at Vanderbilt University in Nashville, Tennessee, around 1920.  They acquired the name after publishing a small literary magazine, "The Fugitive" (1922–1925), which showcased their works.  Although its publication history was brief, "The Fugitive" is considered to be one of the most influential journals in the history of American letters.  The Fugitives made Vanderbilt a fountainhead of New Criticism, the dominant mode of textual analysis in English during the first half of the twentieth century. Margaret Caroline Anderson (November 24, 1886 – October 19, 1973) was the American founder, editor and publisher of the art and literary magazine "The Little Review", which published a collection of modern American, English and Irish writers between 1914 and 1929.  The periodical is most noted for introducing many prominent American and British writers of the 20th century, such as Ezra Pound and T. S. Eliot in the United States, and publishing the first thirteen chapters of James Joyce's then-unpublished novel, "Ulysses". The Harvard Advocate, the art and literary magazine of Harvard College, is the oldest continuously published college art and literary magazine in the United States.  The magazine (published then in newspaper format) was founded by Charles S. Gage and William G. Peckham in 1866 and, except for a hiatus during the last years of World War II, has published continuously since then.  In 1916, "The New York Times" published a commemoration of the "Advocate"'s fiftieth anniversary.  Fifty years after that, Donald Hall wrote in "The New York Times Book Review" that "In the world of the college – where every generation is born, grows old and dies in four years – it is rare for an institution to survive a decade, much less a century.  Yet the Harvard Advocate, the venerable undergraduate literary magazine, celebrated its centennial this month."  Its current offices are a two-story wood-frame house at 21 South Street, near Harvard Square and the University campus. Thomas Stearns Eliot, {'1': ", '2': ", '3': ", '4': "} (26 September 1888 – 4 January 1965) was a British essayist, publisher, playwright, literary and social critic, and "one of the twentieth century's major poets".  He moved from his native United States to England in 1914 at the age of 25, settling, working, and marrying there.  He eventually became a British subject in 1927 at the age of 39, renouncing his American citizenship. Jane Heap (1887 – 1964) was an American publisher and a significant figure in the development and promotion of literary modernism.  Together with Margaret Anderson, her friend and business partner (who for some years was also her lover), she edited the celebrated literary magazine "The Little Review", which published an extraordinary collection of modern American, English and Irish writers between 1914 and 1929.  Heap herself has been called "one of the most neglected contributors to the transmission of modernism between America and Europe during the early twentieth century." Hambone is a small literary magazine that has published major poets.  The magazine is edited by poet Nathaniel Mackey. The Little Review, an American literary magazine founded by Margaret Anderson, published literary and art work from 1914 to May 1929.  With the help of Jane Heap and Ezra Pound, Anderson created a magazine that featured a wide variety of transatlantic modernists and cultivated many early examples of experimental writing and art.  Many contributors were American, British, Irish, and French.  In addition to publishing a variety of international literature, "The Little Review" printed early examples of surrealist artwork and Dadaism.  The magazine’s most well known work was the serialization of James Joyce’s "Ulysses". Jeanne Leiby (September 3,1964 - April 19, 2011) was an American teacher, fiction writer and literary magazine editor.  Leiby's short stories were published in several U.S. literary journals, including "Fiction", "Indiana Review", "The Greensboro Review", and "New Orleans Review".  In 2000, she won the Poets and Writers Writer Exchange.  Her first collection of short stories, "Downriver", was published by Carolina Wren Press as the 2006 winner of the Doris Bakwin prize.  Leiby also served as fiction editor of "Black Warrior Review" and as the Editor in Chief of the "Florida Review" (2004–2007).
