Rukeyser was one of the great integrators, seeing the fragmentary world of modernity not as irretrievably broken, but in need of societal and emotional repair.
— Adrienne Rich
Rukeyser was active in progressive politics throughout her life. At age 21, she covered the Scottsboro case in Alabama, then worked for the International Labor Defense, which handled the defendants' appeals. She wrote for the Daily Worker and a variety of publications including Decision (payne), Life & Letters Today (London) for which she covered the People's Olympiad (Olimpiada Popular, Barcelona), the Catalonian government's alternative to the Nazis' 1936 Berlin Olympics. While she was in Spain, the Spanish Civil War broke out, the basis of her Mediterranean. Most famously, she traveled to Gauley Bridge, West Virginia, to investigate the recurring silicosis among miners there, which resulted in her well-regarded poem sequence The Book of the Dead. During and after World War II, she gave a number of striking public lectures, published in her The Life of Poetry (excerpts here). For much of her life, she taught university classes and led workshops, but she never became a career academic.
In 1996, Paris Press reissued The Life of Poetry, which had been published in 1949 but had fallen out of print. In a publisher's note, Jan Freeman called it a book that "ranks among the most essential works of twentieth century literature." In it she makes the case that poetry is essential to democracy, essential to human life and understanding.
In the 1960s and 1970s, a time when she presided over PEN's American center, her feminism and opposition to the Vietnam War (she traveled to Hanoi) drew a new generation to her poetry. The title poem of her last book, The Gates, is based on her unsuccessful attempt to visit Korean poet Kim Chi-Ha on death row in South Korea. In 1968, she signed the "Writers and Editors War Tax Protest" pledge, vowing to refuse tax payments in protest against the Vietnam War.
In addition to her poetry, she wrote a fictionalized memoir, The Orgy, plays and screenplays, and translated work by Octavio Paz and Gunnar Ekelöf. She also wrote biographies of Josiah Willard Gibbs, Wendell Wilkie, and Thomas Hariot. Andrea Dworkin worked as her secretary in the early 1970s. Also in the 1970s she served on the Advisory Board of the Westbeth Playwrights Feminist Collective, a New York City based theatre group that wrote and produced plays on feminist issues.
Rukeyser died in New York on February 12, 1980 from a stroke, with diabetes as a contributing factor. She was 66.
