The search for new fibers for paper, which went at a very fast speed in the 18th and 19th centuries, was stimulated by the works of naturalists and can be seen in the products of paper makers and printers. During those centuries, rags became ever more scarce as raw material for European paper makers. However, publication of Kaempfer and Du Halde's descriptions of Far Eastern papermaking techniques, which did not require fabric scraps, did not have an immediate impact. Schlosser describes the work of Reaumur, who called attention to wasp nest paper, and Seba, Guettard, J. J. de Lalande, J. C. Schäffer, Leorier de Lisle, Mathias Koops, Claproth, Senger, F. G. Keller, H. Voelters, Burgess, and Watt. -- AATA
