I had always loved expressionist painting, like every European. In fact I admired it all the more because these were precisely the paintings despised by my father's generation.

That was in 1957. And there I found out that Germany is a kind of province. I didn't know anything about expressionism, about the Bauhaus and Dada and surrealism. I was uneducated, so to speak - and everybody else was more or less uneducated, too.

When Michael Werner saw a painting of mine, such as Die grosse Nacht im Eimer, which back then nobody wanted and everybody thought was ridiculous, he realized that this was the right provocation, that it represented the feeling of the times in the right way.

I always work out of uncertainty but when a painting's finished it becomes a fixed idea, apparently a final statement. In time though, uncertainty returns.. your thought process goes on.

What I could never escape was Germany, and being German.

Spending money on art has always been frowned upon in this country - even earlier, when my and others' paintings cost almost nothing. Something is always more important. The people in charge are always peddling reasons that others seem to accept. Those who don't drink and aren't crazy, or who don't attract attention with how they behave in public, aren't noticed in art.

I have always been aware of different movements and directions in art. But, in general, I'm always bored by any kind of generalization when it comes to artists. I think that there are just single individuals, who are valuable, and they work outside of any group.
