First Edition - "Three years after William Beaumont's conjecture (in Experiments and observations on the gastric juice) that gastric juice contained another active ingredient besides hydrochloric acid, Schwann identified this ingredient as the enzyme pepsin. Schwann's paper confirmed the fact, first stated by Prout and later by Beaumont, that the free acid in the stomach is hydrochloric, not lactic as some had claimed". -cf. Norman Schwann's paper " 'Concerning the Nature of the Digestive Process' was easily the most sophisticated treatment of that subject during his time, and if measured against the background of contemporary concepts and methods available, one of the most penetrating of any time. By an interlocked sequence of incisive questions and carefully controlled experiments Schwann systematically narrowed down the many possibilities one could imagine concerning the nature and action of the 'digestive principle' to those alternatives which were compatible with empirical evidence. When he finished he had not only achieved a discovery later regarded as a landmark, but had reformulated the whole problem of what digestion may be. Whatever standard one applies to Schwann's memoir, whether one judges it by the degree to which it surpassed previous knowledge and conceptions of the digestive process or by its conformity to modern descriptions, his achievement was outstanding. The logic of his thought was precise and thorough, his methods were ingenious, and his vision was broad. He redefined the mode of action of the digestive agent and characterized the agent as a chemical substance. He demonstrated its operation on a major class of aliments, but saw beyond the prevalent idea that a single agent is responsible for the digestion of every type of food material. He contributed strong support for the view that digestion involves chemical changes as well as solution. He perceived that the action of the digestive principle comprised one instance of a whole new class of chemical processes peculiarly characteristic of organisms, and he provided a model for the experimental investigation of such processes" cf.

Schwann's paper: pp. 184-193. Clean and fine. First printing of Schwann's milestone paper on fermentation and putrefaction in which he shows that is is not air as such that brings about putrefaction in a meat extract but something in the air, which could be destroyed by heat. The "substances " present in air is germs or seeds of moulds and infusoria, and he explains putrefaction as the action of these germs on access to organic material. He further demonstrates that it is the living nature of the agent that creates fermentation, and he presents new evidence for the nature of fermentation. "Schwann was lead to the idea that alcoholic fermentation was related to the metabolism of yeast by his conception that putrefaction was related to the metabolism of live organisms."(DSB XII, p. 242)."(Schwann) concluded that the processes of putrefaction and fermentation were probably similar in their essence and were due to live agents which obtaineed their sustenance from the fermentible or putrescible materials. It was in the course of these experiments that Schwann discovered and gave an accurate acoount of the yeast plant and its mode of reproducing by budding. In his paper (the paper offered) he anticipated Pasteur's work when he asserted that fermentation of sugar was a chemical decomposition brought about by yeast attacking the sugar and some nitrogen containing substance necessary for its life whereby the elements not used by yeast itself unite to form alcohol. This classical research by him was described by him as 'preliminary' (vorläufige) and at the end of it he promised to return to it. This he did, to a certain extent in his "Mikroskopische Untersuchungen" (1839 - PMM 307 b), and he added new experiments to confirm his view that alcoholic fermentation is due to the activity of the yeast plant."(Bulloch "The History of Bacteriology", pp. 86-87).Schwann gives the "proof that putrefaction is produced by living bodies. Independently of Cagniard-Latour, Schwann discovered the yeast cell. He is regarded as the founder of the germ theory of putrefaction and fermentation."(Garrison & Morton No. 674).

Annal. de l'Acad. Bruxelles, 1895, Imp. J. Bouwens, Brux., 17,2 x 11,2 cm. Theodor Schwann, a German cytologist and physiologist, was born in Neuss, Germany on December 7, 1810. At the University of Berlin, Schwann studied medicine under Johannes Mueller, who taught many 19th century German physiologists. In 1836, while at the University of Berlin, he discovered pepsin, an enzyme responsible for digestion, in extracts from the stomach lining. Pepsin was the first enzyme prepared from animal tissue. In 1837, Schwann showed conclusively that something in the air that was destroyed by heat caused putrefaction, but the air itself did not. Schwann became professor at the Belgium Universities of Louvain, in 1838, and Liège, in 1848. While there, he found that sugar and starch fermentation were the result of life processes, investigated muscular contraction and nerve structure, and discovered the striated muscle of the upper esophagus and the myelin sheath of peripheral axons, called Schwann cells. Schwann coined the term "metabolism" to describe the chemical changes that take place in living tissue and formulated the basic principles of embryology by observing that an egg is a single cell that will eventually develop into a complete organism. Schwann, together with Matthias Schleiden, developed the cell theory in 1839, which identified cells as the fundamental particles of plants and animals. Schwann and Schleiden recognized that some organisms are unicellular while others are multicellular. They also recognized membranes, nuclei and cell bodies to be common cell features and described them by comparison of various animal and plant tissues. These observations and the cell theory were included in Schwann's Microscopical Researches into the Accordance in the Structure and Growth of Animals and Plants published in 1839. Schwann's animal cell theory stimulated a great deal of research. He is now recognized as the founder of modern histology. Theodor Schwann died in January, 1882, at the age of 71.
