Mature critical work Barthes continued to contribute with Philippe Sollers to the avant-garde literary magazine Tel Quel, which was developing similar kinds of theoretical inquiry to that pursued in Barthes's writings. In 1970, Barthes produced what many consider to be his most prodigious work, the dense, critical reading of Balzac's Sarrasine entitled S/Z. Throughout the 1970s, Barthes continued to develop his literary criticism; he developed new ideals of textuality and novelistic neutrality. In 1971, he served as visiting professor at the University of Geneva. In those same years he became primarily associated with the École des Hautes Études en Sciences Sociales (EHESS).
