It started with fast reactions, yes. I mean, I had some problems which I solved before that, but I was really a child still. Now, of course, many co-workers joined me and I really must say now it was always a great pleasure to co-operate with other people, and I never remember that we had a bad atmosphere here, it was always in wonderful way to work together. Many of them became professors there. One of my first students was Gunther Von Bünow, he's now also emeritus already; Gerhard Schwartz, who will be emeritus next year or in a few years; then George Czerlinski, Hartmut Diebler, Kaspar Kirschner, Georg Ilgenfritz and many others. I think you know them.

[Q] Yes, there are some names like Günter Maass, just to mention, and then Eberhard Neumann...

Eberhard Neumann came finally also.

[Q] Friedemann Schneider...

Friedemann Schneider. And many American colleagues and English colleagues... David Hague. And we had Claude Bernasconi who's Swiss, who wrote a book on fast reactions in organic chemistry, and Gordon Hammes, Ken Kustin, Ted Eyring...

[Q] Don Crothers.

Don Crothers, yes, there are many, many... and not only postdocs, many colleagues came and I remember that Al Lehninger spent a year with us, Buzz Baldwin also, he came from the Stanford group. And many colleagues are visiting, like Lars Onsager came for a semester, Peter Debye came as a Gauss Professor to Göttingen, Arthur Kornberg visited, Britton Chance, Hugo Theorell... you remember we played... Hugo was a violinist and his wife, Margit, was a cembalist [harpsichordist], a professional cembalist. And I played four hands with her, and we played trios and quartets and, at the place where you live now, at Schloss Berlepsch, in the Count of Berlepsch and his wife were both also violinists and viola, and we never stopped before four o'clock or five o'clock in the morning, so it was real lively atmosphere, triggered by scientists. Other people came, like Fitzi Lynen, from... famous biochemist of Munich, or Gentner, Fritz Lipmann...

[Q] Max Delbrück...

Max Delbrück yes.

[Q] John Eccles. But there you get into a very long list.

Yes, but if you now review that back then you say what wonderful life that was and what wonderful to work with nice people in a good atmosphere and having interesting questions to discuss.
