Ulises Carrión (b. 1941, Veracruz, Mexico; d. 1989, Amsterdam, Netherlands) studied literature and philosophy at the Universidad Autónoma de México before emigrating to England, where he completed his postgraduate studies in literature at the University of Leeds. In 1972, he settled in Amsterdam where he became a central figure of the mail art movement. There, he co-founded In-Out Books and Other Books and So. Through his writing, curatorial work, and independent publishing projects, he redefined the book as a conceptual and social form. He remained in Amsterdam until his death in 1989.
