Schaeffer, Jacob Christian

Versuche und Muster ohne alle Lumpen oder doch mit einem geringen Zusatze derselben Papier zu machen. 1.

Regensburg 1765. 4to. xii + 56 pp. + 4 hand-coloured engraved plates + 1 engraved frontispiece printed in red + 15 samples of paper numbered 1–15. Presentation copy of the first volume of a series of six volumes (with partly differing titles), with long inscription by the author to Johann Georg Glaesel dated February 3, 1765, bound in original cardboard with copper-coloured cover material richly stamped in blind. One of the most important works in the history of papermaking. Jacob Christian Schaeffer (1718–90) did more than any of his predecessors in the quest for materials for papermaking and he was the pioneer in the use of many vegetable fibres for the fabrication of paper. He published his results in his Versuche 1675–71. As his experiments were carried on previous to the discovery of bleach (the process of bleaching linen and cotton was invented in 1774 by Carl Wilhelm Scheele), his samples of paper have the tint of the original materials from which they were made. There are not many sets of the work extant and the number of specimens in the various sets are not always identical. Dard Hunter, Papermaking. The history and technique of an ancient craft, New York 1943, pp. 237–44.
