Bibliotheca Tinctoria (Edelstein Collection) 517 (“H. was one of the foremost organic chemists of his time... An extensive early 19th-century German treatise on bleaching”). - Sigismund Friedrich Hermbstädt (1760–1833) was a royal court pharmacist and professor of technology and chemistry in Berlin. "He tirelessly... made the findings and the latest results of scientific research applicable to practice in virtually all branches of artisanal and industrial chemical-technological activity, as well as in agriculture. In doing so, he gave many branches of industry a strong boost and helped some achieve international recognition” (NDB VIII, 667). - “Originally strongly influenced by the ‘Beckmann School,’ Hermbstädt had outgrown Beckmann’s understanding of technology. Many of his writings reflect the style of his technology as a description of trades involving chemical operations; however, chemical technology is already emerging as an independent discipline, whose fundamental principles are finding their way into commercial and emerging industrial processes" (Welsch, S. F. Hermbstaedt—Founder of Chemical Technology in Prussia). — Endpaper bearing the stamp of the “Library of the Chemical Factory formerly Sandoz”; a beautiful, decoratively bound copy.
