Jon Juaristi Linacero (born in Bilbao in 1951) is a Spanish poet, essayist and translator in Spanish and Basque, as well as a self-confessed former ETA militant. At the moment he resides in Madrid.
A Ph.D. in Romance philology, he studied at the University of Deusto and in Seville.
He has occupied the chair of Spanish Philology at the University of the Basque Country, the King Juan Carlos I of Spain Center at New York University, and has been titular professor of the Chair of Contemporary Thought of the Cañada Blanch Foundation at the University of Valencia. Juaristi also worked as a lecturer and researcher in Austin and at El Colegio de México. He directed the National Library of Spain from 1999 to 2001, and then left that position to direct the Cervantes Institute until his replacement after the Socialist triumph of March 14, 2004.
At the age of 16, spurred by the reading of Federico Krutwig´s Vasconia, he entered in a fledgling ETA. His most notable action was to put Carlist armed cells in contact with ETA after the expulsion by the Franco regime of Carlos Hugo de Borbón Parma (a pretender to the Spanish throne)
