Le Roy Ladurie, like Derrida, was a fellow-student, and subsequently a professional colleague, sharing an interest in the Occitan peasant culture Bourdieu sprang from. Canguilhem, Bachelard and Koyré were influential teachers Bourdieu sought out while studying philosophy under Althusser. Aron was a guiding spirit, Bourdieu inheriting his mantle at the Centre for European Sociology (where Boltanski was one of the younger group he nurtured). Grass conducted a notable TV discussion with him. Haacke, Adrien and Buren were somewhat unlikely collaborators; Godard however baffled and clashed with him.
