My hometown is Kiel, an important German port and maritime centre on the Baltic Coast. Being a lecturer in economics, in 1977 I started dealing in nautical antiques as a side line. Later on, my interests, and the stock, changed to microscopes and medical items. Located in Hildesheim and having sold several thousend antique microscopes we are always keen to buy early continental microscopes.
