Picture archives of the 'Arbeitskreis Sonnenuhren' -------------------------------------------------
The 'Arbeitskreis Sonnenuhren' (workgroup sundials in Germany) maintains archives with all kinds of pictures of sundials. It is intended to serve as a documentative center for someone giving a lecture as well as being useful if an old picture is wanted to reconstruct a badly preserved sundial. So far the registrar, mathematician Willy Bachmann, can count more than 20.000 photographs and slides! Of course most of them show sundials in Germany (about 15.000) but there are also about 1.200 Swiss, 1.300 Austrian, 1.000 French, 300 Italian, and hundreds of other countries of Europe, Asia, and America. This huge number of items is catalogued well by the aim of a computer of course. The records are linked together with other data bases about sundials giving more detailed information about the gnomonic properties, locations, etc. Nonetheless of the time to be spent into these archives, Mr. Bachmann welcomes more contributions. Dispensible pictures of passable quality of sundials all around the world can be sent to him. But location, name of the photographer, and the year in which it was taken should be given. If one is interested in obtaining copies from these archives this is of course possible. Just write to Willy Bachmann and let him know what you are searching for. But, please, don't forget to include an International Request Coupon to cover postage costs. The registrars address: Bildarchiv des Arbeitskreises Sonnenuhren Dipl.-Math.
