ON SOME SOCIAL CHARACTERISTICS OF THE EIGHTEENTH-CENTURY BOTANISTS René Sigrist* In the eighteenth century, the systematic study of plants was already an old story that could be traced back to the Renaissance and even to clas- sical antiquity. Yet the existence of botany as a science independent of medicine was not as old. It would be difficult to ascertain to what extent it was already a discipline practised by specialized scholars—not to men- tion professionals.1 In 1751 Linné, in his Philosophia botanica, had tried to define the aims and the ideal organisation of such a discipline. Yet, despite the many students who came to hear him in Uppsala, and his eminent position within the Republic of Letters, it was not in his power to impose professional standards on other botanists. Diverging concep- tions of the science of plants persisted at least until the final triumph of Jussieu’s natural method of classification, in the early nineteenth century. The emergence of the professional botanist would be a still longer pro- cess, with important differences from one country to another. The pres- ent article aims to analyse the social status of botanists in the eighteenth century and in the early nineteenth century, a period which can be char- acterised as the golden age of scientific academies.2 Starting with Linné’s conception of the division of tasks within the community of phytologues, it focuses on the social perception of botanists, on the structure of episto- lary links within the Republic of Botanists, and finally on the professional activities and social origins of the major contributors to the science of * Invited scholar (FWO Fellow) at Gent University, Department of Philosophy and Moral Sciences.

The Spirit of Enlightenment (Dordrecht 2001), 4, botany did not become an independent sci- ence before the eighteenth century. He considers (9) that an important quantum jump occurred in 1717 when Sébastien Vaillant positively asserted the sexual character of plants, which had already been foreseen by Camerarius in 1694, but denied by Tournefort the very same year. Another step was the eager adoption by the young Linné of Vaillant’s position as the founding principle of his own system of classification. 2 For the sake of brevity of the term “eighteenth century” will be used in this article, although its empirical basis is extended to the period from 1700 to 1830. © RENÉ SIGRIST, 2013 | doi:10.1163/9789004243910_010 This is an open access chapter distributed under the terms of the CC BY-NC-ND 4.0 license.René Sigrist - 9789004243910 Downloaded from Brill.com10/02/2021 12:40:43AM via free access 206 rené sigrist plants. The dynamic evolution of the community of botanists will also be analysed as a result of growing social demands, and as a condition for a slow process of professionalisation. Linné and the Organization of a Discipline Thanks to the support of Queen Louisa Ulrika and the cooperation of the Swedish East India Company, Linné was in a position to finance travel- lers who allowed him to extend his investigations to the world’s flora and fauna, so as to gather an unprecedented number of specimens and proxy pictures in the gardens and the library of Uppsala. He was thus in a posi- tion to set up an ambitious program of study which served as a model for at least one generation of botanists and marked a kind of turning point in the emergence of botany as a discipline.3 From the sixteenth century onwards, botany had been taught and practised as an auxiliary science of medicine, so that botanical gardens were mainly concerned with the growing of “simples”, that is of medicinal plants or herbs. In 1694, Tourne- fort still defined botany as knowledge of plants and their (medicinal) virtues.4 Boerhaave, whose influence on the teaching and practice of botany was without equivalent in the early eighteenth century, still con- ceived of botany as first dedicated to the study of the curative and nutri- tive properties of simples. His disciples took up his ideas and spread them to Germany (Haller, Trew, Heister), Britain (Sherard), Switzerland (Haller again, Gessner), Austria (de Haen) and of course the Netherlands (Bur- man, Gronovius). Linné himself, although not one of his direct students, came under his influence. In the development of botany as an autonomous discipline, Linné’s role was probably without equivalent, except for the French school of natural classification, centred around the Jussieus, and the institutional settings offered by the Jardin du Roi, the Paris Académie des Sciences, and the Medical Faculty of Montpellier.5 The inventor of the sexual 3 See Gunnar Eriksson, ‘The Botanical Success of Linnaeus.

His science of “growing and living beings” was part of a natu- ral science which considered natural beings, whether mineral, vegetal or animal, as composed entities assembled by God’s will. Its object was to name plants according to their genres and species, with the further aim of characterizing their relations to other types of beings, in order to study the influence of climate and culture and to discover the general laws of their generation.6 Its discoveries, revolutions, progress and methods were established in a series of books published for the most part since 1530: the Bibliotheca botanica. Among the 159 main contributors to the Bibliotheca, only three (Theophrastus, Pliny and Dioscorides) lived in antiquity and two others in the fifteenth century.7 They were therefore excluded from the list of the “founding fathers” of botany, as they belonged to Greek and Roman antiquity or to the Western and Arabic Middle Ages, along with a plethora of their mediaeval and renascent commentators. In the eyes of the “prince of botanists”, members of these groups were ignorant of the two basic principles of modern botany, i.e. the art of general description and the canons and laws which rule the science of the plant kingdom. Linné gave further precision to his concept of the botanist in the form of a taxonomy of phytologues, whose first division opposed real botanists and mere botanophiles. Linné then split the real botanists into two kinds: 1) the collectors, whose duty is to produce and formalize empirical data, and 2) the method- ists, who classify and denominate plants on the basis of the data prepared by the collectors. 1. Among the collectors, Linné first mentions the group of iconographs, who produce figures of plants. This art, ignored by the ancients, is a fun- damental tool for the elaboration of empirical knowledge, which requires the circulation of proxy pictures.8 Yet, since figures only give indications about plant morphology, the iconographs’ work has to be completed by the general descriptions provided by descriptors, whose crucial role, also ignored by the ancients, is to characterize the plants’ features (shape, 6 On Linné’s concept of botany, see Staffan Müller-Wille, Botanik und weltweiter Han- del. Zur Begründung eines natürlichen Systems der Pflanzen durch Carl von Linné (1707–1778) (Berlin 1999), 105–132. Before the Philosophia botanica (1751), the basic principles of the Linnean method had been published in the Fundamenta botanica (1735) and in the Genera Plantarum (first edition 1737). 7 Caroli Linnaei, Philosophia botanica (Stockholmiae 1751), 3–5 (§ 6). 8 Among the most famous iconographs are Anders Hesselius, Johannes Hieronymus Kniphof and Georg Dionysius Ehret, who worked on Linné’s Hortius Cliffortianus (1737).

Linné consid- ers as descriptors such early botanists as Johannes and Caspar Bauhin, but also Dillenius for the mosses, Sloane and Plumier for the American species, and Georg Eberhard Rumpf for the Indian plants. Some of them, the monographs, specialized in a single genre of vegetable (such as the Ginseng for Jacob Breynius). Others, called the inquisitives, focused their attention on rare plants.9 Among the collectors, Linné also ranks the adonides, who teach bot- any on the basis of the specimens gathered in a garden. Among the most famous of these were Pierre Magnol in Montpellier, Hermann Boerhaave and Adrianus van Royen in Leyden, Albrecht von Haller in Göttingen, Linné in Uppsala, and Michelangelo Tilli in Pisa. Then there are the flo- rists, who make a methodical inventory of plants growing ex tempore in a place, usually a province, sometimes a botanical garden. Their aim is to complete the pharmacological teaching of medical students by the adonides.10 Finally, the travellers observe and collect the vegetable prod- ucts of foreign countries.
