Sorry about an error:
The article mentioned in my earlier post was by Daniel Rebour, but he was interviewing Paul Delay. I guess M. Delay must have been well-known, as it doesn't seem to state who he was.
In the interview, after an opening question, M. Delay does all the talking, so it's not an interview in the classical sense... But the words I quoted were M. Delay's, as reported by D. Rebour.
