George Oppen was a poet and activist born in New Rochelle, United States. He was best known as one of the members of the Modernist American poetry group, the Objectivist poets. During the Great Depression, Oppen abandoned his writing practice for political activism, and later moved to Mexico to avoid the attention of the House Un-American Activities Committee for his pre-war activity within the Communist Party. In the 1950s, he returned to poetry and to the United States, and received a Pulitzer Prize for his collection Of Being Numerous (1969).
