I am hoping for some information about this author of sundial books. I have a copy of Sonnenuhren, Eine Anleitung für Handwerk und Liebhaber, Callway, München, 1973.
An excellent and well illustrated book, and I believe that other volumes followed. I would be grateful if members of the list could confirm this, and perhaps supply some facts about Schumacher, such as where he taught, brief biographical details, etc. Regards, Doug --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
