Niedecker's earliest poetry was marked by her reading of the Imagists, whose work she greatly admired and of surrealism. In 1931, she read the Objectivist issue of Poetry. She was fascinated by what she saw and immediately wrote to Louis Zukofsky, who had edited the issue, sending him her latest poems. This was the beginning of what proved to be a most important relationship for her development as a poet.
Zukofsky suggested sending them to Poetry, where they were accepted for publication. Suddenly, Niedecker found herself in direct contact with the American poetic avant-garde. Near the end of 1933, Niedecker visited Zukofsky in New York City for the first time and became pregnant with his child. He insisted that she have an abortion, which she did, although they remained friends and continued to carry on a mutually beneficial correspondence following Niedecker's return to Fort Atkinson.
From the mid 1930s, Niedecker moved away from surrealism and started writing poems that engaged more directly with social and political realities and on her own immediate rural surroundings. Her first book, New Goose
Niedecker was not to publish another book for fifteen years. In 1949, she began work on a poem sequence called For Paul, named for Zukofsky's son. Unfortunately, Zukofsky was uncomfortable with what he viewed as the overly personal and intrusive nature of the content of the 72 poems she eventually collected under this title and discouraged publication. Partly because of her geographical isolation, even magazine publication was not easily available and in 1955 she claimed that she had published work only six times in the previous ten years.
