Commonly considered as conceptional founders of Institutional Psychotherapy (IP)  are François Tosquelles, Jean Oury, Hermann Simon, Frantz Fanon and George Canguilhem. Their work built upon the theory of Jacques Lacan, which was later complemented by Félix Guattari and Gilles Deleuze. Many of these individuals were heavily influenced by the experience of occupation during World War Two; of totalitarian oppression on either side of France. Such personal experiences of incarceration engendered the rethinking of institutional confinement within the psychiatric field, which became a central element to IP. Likewise these individuals had a shared conviction that social and psychological problems should be simultaneously broached, and not studied or treated independently. Within the institution this was addressed through a horizontal, radically democratic therapeutic approach. Two important examples are Saint-Alban in southern France, where IP was initially conceptualised, and La Borde Clinic south of Paris — founded by Jean Oury in 1951 and still open today.
