Jan Luthman lives in England and writes about money matters: investments. But he tells childrens' stories as a hobby. He spent many years overseas with his wife, Jill, living in Africa and the Middle East, and then he returned to England and settled in the Old Farmhouse in a small village in the county of East Sussex in South East England.

If you search the web for Uwe Von Schummann, you can find all kinds of pages.  Make sure you're spelling his name right, because you didn't in the question, and that makes things a little more difficult.

Did you try looking up his name in Yahoo Search?  You could even try pottery, and try to narrow it down.  If he's an unknown, then a reader might know of him.  Good luck.
