During the First World War, when a number of European artists established themselves in New York City, Williams became friends with members of the avant-garde such as
Man Ray, Francis Picabia and
Marcel Duchamp. In 1915 Williams began to be associated with a group of New York artists and writers known as "The Others." Founded by the poet
Alfred Kreymborg and by Man Ray, this group included
Walter Conrad Arensberg, Wallace Stevens, Mina Loy, Marianne Moore and Duchamp. Through these involvements Williams got to know the Dadaist movement, which may explain the influence on his earlier poems of Dadaist and Surrealist principles. His involvement with The Others made Williams a key member of the early modernist movement in America.
Williams disliked Ezra Pound's and especially T.S. Eliot's frequent use of allusions to foreign languages and Classical sources, as in Eliot's
The Waste Land. Williams preferred to draw his themes from what he called "the local." In his modernist epic collage of place,
Paterson (published between 1946 and 1958), an account of the history, people and essence of Paterson, New Jersey, he examined the role of the poet in American society. Williams most famously summarized his poetic method in the phrase "No ideas but in things" (from his 1944 poem "A Sort of Song"). He advocated that poets leave aside traditional poetic forms and unnecessary literary allusions, trying to see the world directly and using a language and form appropriate to the subject itself. Marianne Moore, another skeptic of traditional poetic forms, wrote Williams had used "plain American which cats and dogs can read," with distinctly American idioms.
One of his most notable contributions to American literature was his willingness to be a mentor for younger poets. Though Pound and Eliot may have been more lauded in their time, a number of important poets in the generations that followed were either personally tutored by Williams or pointed to Williams as a major influence. He had an especially significant influence on many of the American literary movements of the 1950s: poets of the
Beat Generation, the
San Francisco Renaissance, the
Black Mountain school, and the
New York School. He personally mentored
Charles Olson, who was instrumental in developing the poetry of the
Black Mountain College and subsequently influenced many other poets.
Robert Creeley and
Denise Levertov, two other poets associated with Black Mountain, studied under Williams. Williams was friends with
Kenneth Rexroth, the founder of the San Francisco Renaissance. A lecture Williams gave at Reed College was formative in inspiring three other important members of that Renaissance:
Gary Snyder, Philip Whalen and
Lew Welch. One of the most dynamic relationships of Williams and his students was with fellow New Jerseyite
Allen Ginsberg. Ginsberg claimed that Williams essentially freed his poetic voice. Williams included several of Ginsberg's letters in
Paterson, stating that one of them helped inspire the fifth section of that work. Williams also wrote introductions to two of Ginsberg's books, including
Howl. Though Williams consistently loved the poetry of those he mentored (his children, so to speak), he did not always like the results of his influence on other poets (the perceived formlessness, for example, of other Beat Generation poets). Williams believed more in the interplay of form and expression.
In May 1963 he was posthumously awarded the
Pulitzer Prize for
Pictures from Brueghel and Other Poems (1962) and the Gold Medal for Poetry of the
National Institute of Arts and Letters. His major works are
Kora in Hell (1920),
Spring and All (1923),
Pictures from Brueghel and Other Poems (1962),
Paterson (1963, repr. 1992), and
Imaginations (1970). The Poetry Society of America continues to honor William Carlos Williams by presenting an annual award in his name for the best book of poetry published by a small, non-profit or university press.
