Archives of the Institut Pasteur: Roux Collection Finding Guide?

Organization and Contents

The finding guide divides Roux's papers into nine major sections, spanning approximately twelve thousand items across multiple formats. The first three sections contain Roux's working notebooks from 1882 to 1910, filed chronologically by date of entry rather than by subject. These manuscripts document his day-to-day laboratory work at the Pasteur Institute, including cultivation techniques for bacterial strains, quantified observations on animal immunization, and early theoretical writings on toxin mechanisms. The notebook entries frequently contain diagrams, sketches of apparatus, and marginal calculations, though many entries remain in nineteenth-century French shorthand that requires specialized knowledge to decipher.

Sections four and five contain Roux's formal scientific correspondence with bacteriologists across Europe, arranged alphabetically by correspondent. The guide notes that letters to Alexandre Yersin, his student and collaborator, comprise the largest single group, with over four hundred items spanning 1888 to 1904. Correspondence with German researchers including Robert Koch and his associates fills a substantial subset of this material, though the guide notes that many of these exchanges concern methodological disputes rather than serum therapy proper. A smaller but significant collection of letters documents Roux's contact with the Institut's administrators regarding funding for serum production and animal husbandry.

Sections six through eight contain publications, printed materials, and miscellaneous items: offprints of Roux's peer-reviewed articles, drafts of articles not published during his lifetime, printed laboratory protocols distributed within the Institut, and receipts and invoices documenting the purchase of equipment and animals. Section nine contains twentieth-century institutional records relating to Roux's posthumous legacy, including correspondence about donations, memorial services, and references to Roux's methods in the work of later researchers at the Pasteur Institute and elsewhere.

Provenance and Condition

The collection was donated to the Institut Pasteur by Roux's family in 1914, two years after his death. The finding guide records that the materials remained stored in the Institut's original location on the Rue Dutot in Paris until 1938, when they were transferred to a climate-controlled storage facility built to house the Institute's growing archives. During the German occupation of France in 1940–1944, the collection remained in Paris and was not disturbed by occupying forces, though the finding guide notes without elaboration that some materials show evidence of water damage from that era.

The systematic cataloguing undertaken beginning in 1958 was directed by Richard Reinhardt, the German bacteriologist who founded the Institute for the History of Bacteriology in Berlin. Reinhardt spent eighteen months at the Pasteur Institute examining and describing the collection, work that resulted not only in the finding guide but also in several scholarly articles published in the Journal of the History of Medicine and Allied Sciences between 1960 and 1964. The microfilm project that accompanied the cataloguing produced approximately eight hundred reels of 35mm film, preserved at the Institut Pasteur and distributed to major research libraries in France, West Germany, and the United States.
