<P> This new idiom, combined with a study of 19th - century French poetry, formed the basis of American input into 20th - century English - language poetic modernism . Ezra Pound (1885--1972) and T.S. Eliot (1888--1965) were the leading figures at the time, with their rejection of traditional poetic form and meter and of Victorian diction . Both steered American poetry toward greater density, difficulty, and opacity, with an emphasis on techniques such as fragmentation, ellipsis, allusion, juxtaposition, ironic and shifting personae, and mythic parallelism . Pound, in particular, opened up American poetry to diverse influences, including the traditional poetries of China and Japan . </P> <P> Numerous other poets made important contributions at this revolutionary juncture, including Gertrude Stein (1874--1946), Wallace Stevens (1879--1955), William Carlos Williams (1883--1963), Hilda Doolittle (H.D.) (1886--1961), Marianne Moore (1887--1972), E.E. Cummings (1894--1962), and Hart Crane (1899--1932). The cerebral and skeptical Romantic Stevens helped revive the philosophical lyric, and Williams was to become exemplary for many later poets because he, more than any of his peers, contrived to marry spoken American English with free verse rhythms . Cummings remains notable for his experiments with typography and evocation of a spontaneous, childlike vision of reality . </P> <P> Whereas these poets were unambiguously aligned with high modernism, other poets active in the United States in the first third of the 20th century were not . Among the most important of the latter were those who were associated with what came to be known as the New Criticism . These included John Crowe Ransom (1888--1974), Allen Tate (1899--1979), and Robert Penn Warren (1905--1989). Other poets of the era, such as Archibald MacLeish (1892--1982), experimented with modernist techniques but were also drawn towards more traditional modes of writing . Still others, such as Robinson Jeffers (1887--1962), adopted Modernist freedom while remaining aloof from Modernist factions and programs . </P> <P> In addition, there were still other, early 20th Century poets who maintained or were forced to maintain a peripheral relationship to high modernism, likely due to the racially charged themes of their work . They include Countee Cullen (1903--1946), Alice Dunbar Nelson (1875--1935), Gwendolyn Bennett (1902--1981), Langston Hughes (1902--1967), Claude McKay (1889--1948), Jean Toomer (1894--1967) and other African American poets of the Harlem Renaissance . </P>
