That summer I was teaching at Les Houches in France, and that I also remember as a particularly happy summer, the summer school which Cécile had founded This is Cécile DeWitt[-Morette] - the same Cécile who had been at the Institute a few years before. And in the meantime she had - I mean she was a real ball of fire and so she had, all by herself she had started this summer school in Les Houches which turned out to be a teaching ground for the whole of Europe and which was an enormous success. So I went - I was there for six weeks of that summer, and I was enjoying that enormously. And I had the most marvellous bunch of students in Les Houches. That's the kind of - I mean it's sort of the antithesis of the PhD. These students came from all over Europe. They were just passionately involved for six weeks in the summer school. There was no problem of exams, no problem of grades or passing degrees or anything. They came just to learn. That was my ideal for a teaching job and, and I think it was just the genius of Cécile to have created it. Anyway, so we had a wonderful summer there. It rained for six weeks without stopping, and one of my students was Georges Charpak, who got a Nobel prize not long ago. They were just a marvellous bunch of students. Almost all of them became famous ultimately.
