Yes, he has the methodical, routine, almost droll teutonic approach to what he does but this should not be mistaken as clinical or academic as he truly is a "man of his time". The sensitivity and thought that goes into what he creates is not always immediate but take some time and with a little patience you will begin to see a great artist at work. His paintings are not empty exercises but embrace a wide range of concepts and human emotions. Gerhard is getting older but his mind is as sharp as ever. I'm always wondering what he'll do next and what stone remains for him to turn over.
I'll be coming back to Gerhard later to look at his work more closely!
Please take the time to investigate him further; there is a lot to be learnt from him.
