Following the war, from 1960 to 1964, Derrida taught philosophy at the Sorbonne, where he was an assistant of Suzanne Bachelard (daughter of Gaston), Georges Canguilhem, Paul Ricœur (who in these years coined the term "school of suspicion") and Jean Wahl. His wife, Marguerite, gave birth to their first child, Pierre, in 1963. In 1964, on the recommendation of Louis Althusser and Jean Hyppolite, Derrida got a permanent teaching position at the ENS, which he kept until 1984. In 1965 Derrida began an association with the "Tel Quel" group of literary and philosophical theorists, which lasted for seven years. Derrida's subsequent distance from the "Tel Quel" group, after 1971, has been attributed to his reservations about their embrace of Maoism and of the Chinese Cultural Revolution.
