In the early years of the twentieth century, Catholic libraries in Germany adopted modernized methods of organization to simplify their use: the arrangement of books by subject, alpha-numeric classifying systems, and card catalogs. The adoption may not seem like much, but in the structure and practice of Catholic knowledge the change was fundamental. How did this revolution come about and what did it betoken?
Francis Bacon’s belief that “knowledge is power” is one of the great epistemic mottos of all time. In early nineteenth-century Jewish Amsterdam, where civic emancipation had overturned the old corporate hierarchies, the rabbinic elite soon came to experience its merciless truth. In the newly established Kingdom of the Netherlands (1814), both their position and their expertise were pushed to the margins. To make things worse, the centralized organization of the newly constituted Israelite Denomination left no room for German-style Reform–Orthodox dualism. As a result, innovation and consolidation all took shape within a single, outwardly stable, yet inwardly polarized community, in which conservative rabbis and progressive lay executives vied for initiative and control. This perpetual state of discord posed high demands on a rabbi’s personal skills. It was no longer enough to be a competent teacher and judge; in order to survive, the rabbi had to become a kind of statesman. But what in his rabbinic experience would provide him with the wherewithal to become a politician?
On November 4, 1646, Sir Theodore de Mayerne (1573–1655), first physician to Charles I and the English Aristocracy, decided to spend his day away from his demanding patients and to devote his attention to the vibrant world of colors. He took a good handful of bilberries and carefully inspected the color of their peel and pulp. He then cooked them following a recipe for making a “very beautiful and very oriental” colorant for writing and limning. The recipe he followed has survived as part of an extensive manuscript collection dated to the first half of the seventeenth century.

The early modern household was a bustling site for a range of medical activities from self-diagnosis and medication to nursing and caring for the sick to drug production. To further their knowledge about medicine and the body, householders accessed a wide variety of sources. Many turned to their family and friends for health-related advice, consulted medical practitioners of various sorts, and avidly read the abundance of printed medical books offered by contemporary book producers. By the mid-seventeenth century, the bookshops near St. Paul’s in London were stocking an astonishing array of English medical books. Readers could pick and choose from an assortment of herbals, pharmacopoeias, general medical guides, surgical handbooks, midwifery manuals, regimens, medical recipe books, and more. These texts were eagerly consulted by householders, who utilized the knowledge contained therein not only for their home-based medical activities but also as a way to inform their decisions as actors in medical encounters with practitioners of all sorts.

In 1901, Erich von Tschermak (1871–1962) produced a critical edition of Gregor Mendel’s (1822–1884) paper on “Versuche über Pflanzenhybriden”; and in the same year, William Bateson (1861–1926) submitted an English translation entitled “Experiments in Plant Hybridization” to the readers of the Journal of the Royal Horticultural Society. Tschermak’s edition appeared as volume 121 of the renowned series Ostwalds Klassiker der exakten Naturwissenschaften (Ostwald’s Classic Texts in the Exact Sciences). Historians have rarely noted the paradox that lies in the fact that a paper, which scientists like von Tschermak and Bateson had lifted from obscurity just a year earlier, was almost instantaneously included in the Pantheon of classical contributions to the “exact” sciences. The discipline that Mendel supposedly founded, namely genetics, did not yet exist in 1901, and his alleged “discovery” of laws of inheritance would remain highly contested for at least another decade, even involving accusations of scientific misconduct.
