Félix Guattari (1930–92) worked as a psychoanalyst at the experimental psychiatric clinic La Borde in Cour-Cheverny, France. By 1953 he had entered the gravitational field of Jacques Lacan's seminar, and later became his analysand. Guattari participated in many far-left political organizations, engaged with the struggles of social movements such as anti-psychiatry, while not adopting the name, and turned to green politics in his later years. He supported the free radio movement in the mid 1970s, and assisted his Italian friends such as Antonio Negri and Franco Berardi in the autonomist movement during a period of state repression.

His books include Psychanalyse et transversalité (a collection of early articles published in 1972), La Révolution moléculaire (two different editions appeared in 1977; partial translation in 1984), Les Années d'hiver (occasional pieces from 1980–86), Cartographies schizoanalytiques (1989), The Three Ecologies (1989; English trans. 2000) and Chaosmosis (1992; English trans. 1995). Posthumously, his letters to Deleuze and preparatory notes were published in The Anti-Oedipus Papers (2004; English trans. 2006). Guattari collaborated with Gilles Deleuze on Anti-Oedipus (1972; English trans. 1977), Kafka (1975; English trans. 1986), A Thousand Plateaus (1980; English trans. 1987) and What is Philosophy? (1991; English trans. 1994). Guattari also collaborated with Antonio Negri on Communists Like Us (1990), and with Suely Rolnik on Molecular Revolution in Brazil (2008). Guattari's interview with Luiz Inácio Lula da Silva, current president of Brazil, is included in The Party without Bosses (Genosko 2003). Key edited collections include The Guattari Reader (1996a) and Soft Subversions (1996b).
