Perec and Virilio were Duvignaud’s main collaborators in his review ‘Cause Commune.’ Virilio, trained in stained-glass work, worked alongside Matisse in Paris churches in the years following WWII, as well as with Braque. He studied phenomenology under Merleau-Ponty, had an architectural practice with Parent, and during the 1968 ‘events’ in Paris, found himself alongside Beck, helping take over a theatre. Lefebvre and Deleuze were intellectual colleagues with whom he also had political disputes.
