Ludwig, Johann Adam Jakob
- Hans Klotz
( b Sparneck, Upper Franconia, Oct 1, 1730; d Hof, Jan 8, 1782). German critic and writer on organ building . He was a postal clerk in Hof and, after 1764, accountant at the Vierling bookshop. He was a member of several scientific and economic societies and his contact with distinguished organ builders (such as J.A. Silbermann) enabled him to acquire a thorough knowledge of organ building. Ludwig was a friend and business partner of G.A. Sorge (whom he supported in his polemical arguments, interspersed with personal insults, with F.W. Marpurg), and probably wrote the pamphlet Eine helle Brille für die blöden Augen eines Albern Haberechts zu Niemandsburg, which was published anonymously during these polemics. His writings contain valuable information about J.J. Graichen (1701–60) and J.N. Ritter (1702–82), pupils of Gottfried Silbermann working in Franconia.Versuch von den Eigenschaften eines rechtschaffenen Orgelbauers (Hof, 1759) Gedanken über die grossen Orgeln, die aber deswegen keine Wunderwerke sind...
