Lyn Hejinian was an American poet, essayist, translator, and publisher, and a central figure in the Language poetry movement that emerged in the Bay Area in the 1970s. Her work reflects a sustained attention to the musical, formal, and social dimensions of language, and her practice was often collaborative, extending into interdisciplinary projects with painters, musicians, and filmmakers. She was the founding editor of Tuumba Press; co-editor of Poetics Journal; translator of the Russian poet Arkadii Dragomoshchenko, helping to forge vital connections between Language poets in the United States and experimental writers in Russia; and a professor at the University of California, Berkeley.
