In 1976 Wittig and Zeig moved to the United States where Wittig focused on producing work of gender theory. Her works, ranging from the philosophical essay "The Straight Mind" to parables such as "Les Tchiches et les Tchouches", explored the interconnectedness and intersection of lesbianism, feminism, and literary form. With various editorial positions both in France and in the United States, Wittig's works became internationally recognized and were commonly published in both French and English. She continued to work as a visiting professor in various universities across the nation, including the University of California, Berkeley, Vassar College and the University of Arizona in Tucson. She taught a course in materialist thought through Women's Studies programs, wherein her students were immersed in the process of correcting the American translation of "The Lesbian Body". She died of a heart attack on January 3, 2003.
