Of course, you have to make decisions, whether you want to be a statesman, politician, or scientist, an artist.  You can't do everything and you have to do what you do, you have to do carefully and as well as possible. So there were often the questions whether I take over a presidency of a larger organisation... including the Max Planck Society and others... and I said, 'No, this is not my goal in my life, and I'm not a born president of a larger organisation'. I realise that Einstein thought along the same way. After the war they asked him to become the President of Israel and he said, 'No that's not my business. I'm a scientist and I will go on and do...' And that's a little bit my credo. But, of course, you have duties towards society. So I thought I looked for certain positions which I ought to do, where I think I have to pay something to society, and one was the Studienstiftung. The Studienstiftung is an organisation in Germany which furthers gifted young people in both arts and sciences. In the arts, in music, in painting, in sculpture and in all the sciences including humanities. So, they must really be top people, they must be real talents. And then they are funded and one helps them also to produce a thesis and so on. And I thought this was some task for me, that I had to do something in that. The money we spend is about thirty, forty million per year, it might now have increased. I retired from that post when I retired from my scientific career. But I thought here I can do something to society, furthering young talents, furthering young people, and I must say it was a very satisfactory arrangement. I had to talk to ministers and make sure that the support was given, but so far it worked out. This is one of the... of course I did also some obligations in science organisation. I mentioned already that I took over the presidency of the European Molecular Biology Organisation.
