Mateu Orfila and the affaire Lafarge

After a short illness, Monsieur Lafarge passed away at the dawn of January, 14th, 1840. His young wife was accused of murder by poisoning and put in prison. A week after, local experts were requested to make an autopsy and a chemical test. They found traces of arsenic – its characteristic garlic smell, a yellow sulphurous precipitate - but they could not give a conclusive answer to the court. Three additional expertises were made without positive conclusions. Almost at the same time, Mateu Orfila was giving a series of conferences the Paris Academy of Medicine about a new toxicological device: the Marsh test. The new instrument had been introduced in 1836 and Orfila and other toxicologists regarded it as a revolutionary method to discover arsenic in legal expertises. In September 1840, by applying Marsh’s apparatus to the mortal remains of Monsieur Lafarge, he obtained a group of arsenic spots and Madame Lafarge was sentenced to life imprisonment. Not all the experts followed Orfila in his conclusions. The physician, socialists and republican activist François V. Raspail wrote incendiary leaflets against Orfila asking for the release of Madame Lafarge. During the next year, the debate reached the Academy of Science and the Academy of Medicine. The French press gave a large coverage to the trial and Marsh test gained a large publicity and became much more famous than any other contemporary scientific instrument. Marsh essays were done in French saloons, public lectures and even some plays recreated the Madame Lafarge’s drama, which has lasted in French collective memory until nowadays. Therefore, the affaire Lafarge provides a large and rich documentation to explore how a new controversial test was transformed into something that all toxicologists took for granted by the middle of nineteenth century. The paper explores how Marsh test was black boxed in the changing context of nineteenth century French legal medicine.

Bones of Contention: Orifla, Normal Arsenic, and British Toxicology

Mattieu Orfila’s announcement in 1839 that arsenic was a natural constituent of the human body caused a stir in the British medico- legal world. Toxicology at this time was the most conspicuous of the rising sub-fields within British medical jurisprudence, its practitioners busy staking out its claims as a stable body of expert knowledge that could be relied upon by criminal courts, and by the public at large. Toxicological proof, in its ideal form, involved the isolation and extraction of a "foreign" substance, clearly identifiable as a poison, from otherwise "pure," "uncontaminated" flesh. This was by no means a straightforward task, however: in the courtroom, a toxicologist’s claim to have identified a poison was always in danger of being subverted by other meanings attributable to its presence in the body. Substances like arsenic, for example, were liable to slip out of the toxicologist’s definitional grasp by being designated a medicine rather than a poison. Orfila’s "discovery" exacerbated toxicologist’s difficulties in stabilizing arsenic, and was accordingly greeted with a combination of exasperation and skepticism. Yet at the same time, Orfila was a significant figure in British toxicology’s account of its own rise as a credible science. The normal arsenic controversy thus raises questions about the conceptual foundations of early British toxicology, its relationship to its continental counterparts, and its efforts to manage the contested domain of the adversarial courtroom.

Organic and Biological Chemistry in a Medical Context: The Research School of Adolphe Wurtz at the Faculty of Medicine, Paris (1853-1884)

This paper addresses the status and relationship between organic chemistry and biological chemistry while the Alsatian chemist Adolphe Wurtz taught and established a research school at the Faculty of Medicine of Paris. In 1853, following the death of Mateu Orfila and Dumas’s resignation from his professorship at the Faculty of Medicine of Paris owing to his political engagements, their respective chairs of ‘medical chemistry’ and ‘chemistry’ were combined into a single one titled ‘organic and mineral chemistry’. Adolphe Wurtz, who between 1847 and 1853 held the positions of agrégé de chimie and of Dumas’s suppléant at the Faculty of Medicine, was appointed professor to this new chair, thereby securing his position within the institution. According to various testimonies, his lectures were crowded, and his disciple Charles Friedel later made the comment that ‘it was not simply an audience he [Wurtz] found at the Faculty of Medicine but all that was required to create a true school of chemistry’. However, a closer examination shows that for a variety of reasons, which will be analysed, Wurtz’s research school recruited most of his students outside the Faculty of Medicine. His research programme focussed mainly on fundamental organic chemistry, and biological chemistry was for some time more of a teaching activity than a strong line of research. In 1873, Wurtz seems to have overcome his hesitations regarding biological chemistry, and while he was Dean of the Faculty of Medicine, a separate laboratory for biological chemistry was created, his disciple Armand Gautier being appointed its director.

Orfila and French legal medicine nineteenth-century

La réception d¹Orfila en France fut précoce. Dès le Premier Empire il sut trouver le ton pour s¹adresser au monde savant et séduire les pouvoirs. Son influence sur la médecine légale fut essentielle, entre la fin de la Resauration et la fin de la monarchie de Juillet. Orfila charma presque immédiatement les contemporains par sa personnalité. Reçu partout avec empressement, il savait ³allier le goût du monde et des plaisirs à une facilité extraordinaire pour le travail². Le cours de chimie qu¹il ouvrit en 1811 à Paris l¹atteste. Le soin qu¹il mettait à le préparer et surtout sa ³parole élégante² lui garantissaient le succès et le soutien de Vauquelin ou Fourcroy. En 1819, il devint professeur de médecine légale à la faculté de médecine de Paris, avant d¹occuper par la suite d¹autres fonctions. La monarchie de Juillet consacra son triomphe. Il fut à la fois le porte-parole du pouvoir, la première personnalité du monde médical, un administrateur infatigable, un chirurgien recherché, un chimiste renommé, un expert judiciaire sollicité. Il règna sans partage, "ennivré d¹encens", sur un petit monde. Toutefois ce sont ses travaux sur la toxicologie légale et la médecine légale qui assurèrent aurpès du monde savant son rayonnement. L¹ouvrage le plus important fut assurément ses Leçons de médecine légale (1821-1823), régulièrement étoffées (Leçons de médecine légale, Planches, 1825) puis éditées sous la forme d¹un Traité de médecine légale (1847)en 4 volumes qui impressiona le monde médical et judiciaire par son approche et son découpage. Pour comprendre la place prise par cette somme, il convient à la fois de s¹attacher à son analyse interne et aux échos que l¹on peut rencontrer dans les Dictionnaires, en particulier le Dechambre, monument lexicographique édifié à la gloire de la médecine. Régulièrement, il fut sollicité pour réaliser des expertises et La Gazette des tribunaux, le plus célèbre périodique judiciaire du siècle, fit de très nombreux comptes-rendus des procès d¹assises, restituant pour son lectorat, la parole de Matthieu Orfila. Toutefois, pour saisir toute l¹importance de son oeuvre, il convient d'abord de s'attacher à son impact auprès des ³médecins judiciaires² de sa génération. Comme lui, ils étaient désignés par la Justice pour remplir des missions et ont écrit des essais, des manuels ou des traités, à l'instar d'Alphonse Devergie, dont la troisième édition de son livre, intitulé Médecine légale, théorique et pratique, date de 1852, un an avant la mort d'Orfila . Mais il importe également de se placer à la fin du grand XIXe siècle pour observer la place qu¹occupent encore ses recherches, notamment dans le Précis de Charles Vibert (1896).

Teaching chemistry for medical students: Public and private courses of chemistry in Paris during early nineteenth- century

As many other contemporary practitioners of chemistry, teaching activities played an important role in Orfila's scientific and professional career. Orfila lived in a period when chemistry started to no longer be a knowledge taught in apothecary workshops and unregulated public courses to became an academic discipline included in the curricula of the old and new institutions of secondary education, universities and technical schools that emerged in the main European capitals of this period. This strong process of institutionalisation did not have as a consequence the immediate disappearing of the traditional way of teaching. Both shared and interacted for decades offering the new students of chemistry a network of courses and training pathways that each one could follow according to the their necessities and possibilities, as well as an ample variety of ways to become a professional. From the very first years as student in Valencia, Barcelona and Paris, up to his professional zenith in the Faculty of Medicine of Paris, the professional and scientific biography of Orfila take us through many of these new training and professional itineraries of the chemistry. The study of the spaces, contents and practises of the teaching of chemistry through the life and work of Orfila has a double interest. On one hand it will enable us to get closer to the institutional and pedagogical contexts that Orfila crossed as a student or teacher in his career. On the other hand it will enable us to know better this dimension of Orfila's biography and its meaning as part of his scientific activity.

The disintegration of plant and animal chemistry and the formation of carbon chemistry around 1830

Eighteenth- century plant and animal chemistry was not only the chemistry of substances, and of reactions of substances, but also the chemistry of living natural bodies. In this chemical culture, the objects of inquiry spanned from complex organised bodies, such as entire plants and their organs, through plants' and animals' anatomy and physiology, to the extraction of materials from plants and animals and the natural materials' analysis and pharmaceutical application. Chemists' descriptive, natural historical goals mingled with their analytical, more theoretical interests, and with their interests in medicine and pharmacy. By contrast, in the new experimental culture of organic chemistry, or "carbon chemistry," which developed in France and Germany between the late 1820s and the 1840s, chemists were preoccupied with pure organic (or carbon) compounds. They performed experiments to investigate the invisible constitution of pure organic compounds and their reactions in the laboratory. In doing so, they created a plethora of new organic artefacts which did not exist in nature outside the laboratory. In particular the extension of experimental investigations of a new kind of organic chemical reaction, namely substitution reactions, contributed to the exponential increase of organic artefacts and a deep transformation of the meaning of "organic" compounds. Chemists further established a new kind of work on paper to model the constitution and reactions of organic compounds, and to create new types of classificatory systems, by applying Berzelian chemical formula as papers tools. The new "experimental culture" of carbon chemistry excluded objects of investigation that were traditionally not studied by way of experimentation, namely plant and animal physiology, and the pharmaceutical and medical application of organic substances. On an institutional level, the formation of carbon chemistry went hand in hand with the formation of other chemical sub- fields that were previously included in plant and animal chemistry, such as physiological chemistry, medical chemistry, and pharmaceutical botany.

Building a discipline: medical chemistry in early nineteenth century

On the basis of a programme established by A.F Fourcroy, medical chemistry was developed by systematically applying the resources of chemistry for the purpose of building a new pathology. Some of his followers and founders of the Société de Chimie Médicale contributed to the institutionalisation of this discipline in Paris at the time of the Restoration. However, developing contents for this new discipline was not the main objective of the society’s promoters. The persons who studied pathological processes from the perspective of chemical analysis were physicians, pharmacists and chemists that were not directly involved in the society. The purpose of this paper is to analyse, through the study of papers published in French scientific journals and of their authors, the process by which medical chemistry developed.

The toxicology of Robert Christison: European influences and British practice in the early nineteenth century

Robert Christison (1797-1882), the third professor of Medical Jurisprudence and Medical Police [forensic medicine] at the University of Edinburgh, was the first British exponent of 'modern' toxicology to acquire an international reputation. He was viewed as one of the chief European toxicologists in Orfila's tradition; a reputation sustained for some years particularly by several reprints of his book A treatise on poisons, in relation to medical jurisprudence, physiology, and the practice of physic (1829). Christison's reputation was also secured by some sensational poisoning trials, where he gave evidence for the prosecution. We will examine the European influences on Christison's work, the reasons for his reputation as a leading toxicologist, and his influence on the training of British doctors in toxicology.
