Yuriy Orest Ivanovych Tarnawsky (February 3, 1934 – October 14, 2025) was a Ukrainian-American writer and linguist, one of the founding members of the New York Group of Poets, a group of avant-garde Ukrainian diaspora writers, co-founder and co-editor of the journal New Poetry, as well as a member of the US innovative writers' collaborative Fiction Collective.D. H. Struk. Encyclopedia of Ukraine, Toronto University Press Incorporated, 1993. He wrote fiction, poetry, plays, translations, and criticism in both Ukrainian and English.

Life and career Early years Tarnawsky was born on February 3, 1934, in the town of Turka in western Ukraine, at that time under Polish rule. His mother was a school teacher and his father a school principal. He spent 1934 to 1940 in Poland, near the town of Rzeszów, before moving near Sanok and in Turka. In 1944 he emigrated with his family to Germany. After the war, Tarnawsky lived in a Displaced Persons' camp in Neu Ulm, Bavaria where he attended first Ukrainian and then German secondary schools. Tarnawsky graduated from High School in Munich in February 1952, before emigrating with his family to the United States and settling in Newark, New Jersey. There he attended the Newark College of Engineering, now New Jersey Institute of Technology, from which he graduated with honors in 1956 with a bachelor's degree in Electrical Engineering.

Upon graduation, Tarnawsky was hired by the IBM Corporation in Poughkeepsie, NY, and worked there until 1992. At IBM, he worked first as an electronic engineer and then as a computer scientist, primarily in regard to automatic language translation from Russian into English. He managed groups of applied linguists at IBM's Thomas J. Watson Research Center in Yorktown Heights, NY, in the US military school in Syracuse, NY, and at the Library of Congress in Washington, DC. The program developed under his leadership was exhibited at the 1964 World's Fair in New York and was the first in the world to have practical application.

During the years 1964–65, on leave from IBM, Tarnawsky lived in Spain, devoting his time to literary work. Later, while continuing to work for IBM, he studied theoretical linguistics at New York University, obtaining a PhD degree in 1982. His doctoral dissertation Knowledge Semantics in the field of transformational-generative grammar deals with the semantic component within Noam Chomsky's Revised Extended Standard Theory and argues against decompositional semantics. It has been described as being revolutionary in combining the views of Noam Chomsky and Hilary Putnam into one formulation.R. C. Dougherty. Preface, Y. Tarnawsky. Znannyeva Semantyka, National University of the Kyiv-Mohyla Academy, 2016. After completing his linguistic studies, Tarnawsky worked on computer processing of natural languages and the development of artificial ones as well as in the area of Artificial Intelligence.

For his work at IBM he received a number of awards.

He has authored numerous articles on computational and linguistic topics.

After leaving IBM under an early retirement program, Tarnawsky joined the staff of the Harriman Institute at Columbia University in New York City and was a professor of Ukrainian Literature and Culture in the Department of Slavic Languages as well as co-coordinator of Ukrainian Studies (1993–1996).

In 2016, Tarnawsky oversaw the publishing of Knowledge Semantics () by the National University of the Kyiv-Mohyla Academy. It is the first publication in the field of transformational-generative grammar in the Ukrainian language and is augmented by an extensive English-Ukrainian and Ukrainian-English dictionary in which Tarnawsky developed the basic transformational-generative linguistics terms for Ukrainian.

Tarnawsky is one of the founding members of the New York Group, a Ukrainian émigré avant-garde group of writers, and co-founder and co-editor of the journal New Poetry (1959-1972). While at Columbia University, he was instrumental in founding the archive of the group at the university's Rare Book and Manuscript Library to which he has contributed his papers. His first volume of poetry Life in the City (1956, in Ukrainian), with its urban motifs and concentration on the theme of death, was received by critics as a new word in Ukrainian poetry, such that broke with the language and subject traditions of Ukrainian literature and laid down a path which many of his contemporaries were to followY. Lavrinenko. "An Uprising Against Decay," Ukrainian Literary Gazette, No. 9, 1956.B. Rubchak. The Poetry of Antipoetry, Suchasnist, No. 4, 1968. The declaratively existentialist novel Roads (1961, in Ukrainian), which deals with the life of German youth in post-war Germany, is likewise considered a new word in Ukrainian fiction.Y. Lavrinenko. "New Continent of the Soul," Letters to Friends, No. 3-4, 1963.I. Kostetsky. A Stroll Through the Bookstore. Suchasnist, Ukraine and the World, No. 24. 1962. The roots of Tarnawsky's early works lie almost exclusively in Western literature, in particular in Hispanic poetry and the poetry of the French pre-symbolists, surrealism, and the philosophy of existentialism.I. Kotyk. Existential Dimension of Man in the Poetry of Yuriy Tarnawsky, Lviv Branch of National Academy of Sciences of Ukraine, 2009. M. G. Bartolini. In the Tight Triangle of the Night, Editore: Lithos, 2012. With time, his technical and linguistic background began to exert more and more influence on his literary work, as a result of which it employs a radically new use of language, as for instance in the volumes of poetry Without Spain (1969, in Ukrainian) and Questionnaires (1970, in Ukrainian) and the novels Meningitis (1978, in English) and Three Blondes and Death (1993, in English).M. Bérubé. The Employment of English, New York University Press, 1998. In the 1960s Tarnawsky switched fully to writing in English, first in fiction and then in poetry; although in the latter he subsequently made Ukrainian versions of the English-language works (the volume This Is How I Get Well (1978) and the next five collections). He joined the group of innovative American writers Fiction Collective (later FC2) and published with it the novels Meningitis and Three Blondes and Death, both of which received high praise from US critics. (Three Blondes and Death, for instance, was compared by one reviewer to the skyscrapers of Mies van der Rohe and Gropius which towers over the cottages of contemporary American fiction.) H. Polkinhorn. Through a Cold and Disorienting Fog, American Book Review, August, 1993.

With Ukraine's independence, which came in 1991, Tarnawsky returned to writing in Ukrainian, publishing literary works and articles in the press as well as separate books. His works now show elements characteristic of postmodernism, such as polystylism, collage, pastiche, and the taking on of many, sometimes opposing, stances or masks (for instance, the poetry collection An Ideal Woman (1999), the book-length poem U ra na (1992) and The City of Sticks and Pits (1999), as well as the cycle of plays 6x0 (1998), all in Ukrainian).T. Hundorova. Deconstruction on the Background of a Masculine Text, Krytyka, No. 9, 1999. This process culminates in the publication of a three-volume set of his writings in Ukrainian—6x0 (1998, collected plays),They Don't Exist (1999, collected poetry 1970–1999), and I Don't Know (2000, new version of Roads, excerpts of his English-language books of fiction Seven Tries, and the autobiography Running Barefoot Home and Back). His own Ukrainian-language version of the English-language collection of stories Short Tails that shows the influence of existentialism, absurdism, and postmodernism, was published in Ukraine in 2006. Flowers for the Patient, a book of his selected essays and interviews in Ukrainian, came out in 2012.

In recent years, Tarnawsky has been dedicating himself more and more to writing in English. Thus, 2007 saw the publication of his collection of mininovels (his own genreS. Moore. The Novel, an alternative history, Continuum, 2010.) Like Blood in Water, and 2011 of the original version of the collection of short stories Short Tails, reformatted and expanded over the Ukrainian-language version. The Placebo Effect Trilogy, three collections of interrelated mininovels—Like Blood in Water (revised edition), The Future of Giraffes, and View of Delft—were published in 2013. The trilogy and its volumes may be viewed as a novel/novels, unified not by characters and events, as is the case in traditional fiction, but by the common topics of existential despair, fear of death, and alienation, which, like motifs in music, bind them into a whole. 2013 also saw the publication of his first book of poetry in many years, Modus Tollens, subtitled "IPDs or Improvised Poetic Devices," which require the reader's active participation and which Tarnawsky calls Heuristic Poetry. Still another collection of his short fictions Crocodile Smiles, subtitled "Short-Shrift Fictions," which extends further the absurdism of Short Tails, was published in 2014 (expanded edition in 2020). One of its stories, "Dead Darling," was previously published in the anthology Best European Fiction 2014 by Dalkey Archive Press. His two 2019 novels have uncharacteristically realistic settings—Warm Arctic Nights is a fictionalized memoir of his early years in Poland and Ukraine, presented in the form of an interview, and The Iguanas of Heat with its detailed US and Mexico settings and ostensibly a suspense story, is a painstaking deconstruction of a sterile marriage. Claim to Oblivion, his book of selected essays and interviews in English, which deal primarily with his own literary works and the issues he tackles in them, was published in 2016. The 2018 book of exercises Literary Yoga effectively illustrates Tarnawsky's views on the craft of writing.

From the end of the 1990s Tarnawsky was active in the U.S. innovative writing community, participating in the AWP and &NOW conferences.

Tarnawsky devoted a lot of energy to translating from Ukrainian into English and from various languages into Ukrainian. Among other works, he is the co-author of the English translation of Ukrainian epic poetry dumy published as Ukrainian Dumy by Harvard Ukrainian Research Institute in 1979.
