[Foucault-L] Herodote

I hope someone can help

In the mid 1970s some geographers at the Herodote journal responded to
questions from Foucault (a followup to the Questions on Geography translated
in Power/Knowledge). I've tracked down several, but am trying to find out
information about the following authors

- Jean-Michel Brabant
- Michel Riou

Any information on their institutional location then or now would be very
much appreciated.

This info is needed for a book entitled Space, Knowledge, Power: Foucault
and Geography, edited by Jeremy Crampton & Stuart Elden, Aldershot: Ashgate,
forthcoming 2006.

Thanks

Stuart
