Archives and Records?

Archives and records in the twentieth and twenty-first centuries reflect the fundamental reorientation of medicine around infection prevention rather than curative treatment. Because systemic bacterial infection remained largely untreatable by chemical means, the documentary record shifted decisively away from clinical narrative and toward enumeration: hospitalization rates, surgical protocols, quarantine orders, serum batch efficacy, and mortality statistics by cause. The surviving archives tell a story not of discovery but of containment — the elaborate bureaucratic machinery built to track, quantify, and prevent bacterial disease when cure remained out of reach.

The transformation began during the 1940s, when World War II field hospitals first accumulated large systematic records of untreated septicaemia outcomes. Military medical officers, facing catastrophic infection rates in wounded soldiers, began recording mortality not by patient name but by wound type, time to sepsis onset, and causative organism. These records, held in military archives across Europe and North America, document the pivotal realization that no chemical class would arrest systemic infection once it had begun. The statistical turn in medical recording — away from individual case histories and toward population-level data — originated in this moment of clinical defeat.

The Bacillary Congress of Geneva in 1952 formalized this transformation. The congress produced not a set of treatment guidelines but a standardized reporting framework: the protocols for documenting asepsis maximalism practice. Participating nations agreed to track surgical site infections by procedure type, hospital architecture classification, and staff compliance with prevention measures. The Geneva Sanitary Bureau, established immediately after, inherited responsibility for collecting and comparing these reports. Its archives, maintained continuously since 1952, contain the quantitative foundation of modern infection control practice — millions of individual surgical records, coded and tabulated, showing infection rates by protocol adherence, by ward design, by season and staffing level.

The Institute for the History of Bacteriology, founded in Berlin in 1956 under the direction of Richard Reinhardt, exists primarily as an archive. Its collections hold institutional records from dozens of hospitals across Western Europe, documenting the adoption and refinement of asepsis maximalism protocols. More valuable still are the research papers, laboratory notebooks, and correspondence relating to serum therapy development. The Archives of the Institute for the History of Bacteriology: Umezaki Papers preserve decades of work by Dorothy Umezaki and her colleagues, including raw survival data from serum therapy trials, patient records, and the incremental refinement of serological techniques. The institute's strength lies not in interpretation but in preservation: it houses the physical evidence of how medicine remade itself around prevention.

The Bayer AG Manufacturing Archives, held at company headquarters in Leverkusen, document the production history of azo drugs from the 1930s onward. These records, made systematically available through the Archive Organization and Access: The Bayer Finding Guide Project between 1987 and 1994, show sulfonamide synthesis, wartime rationing, production shortfalls, and the relationship between chemical manufacturing capacity and clinical availability. They reveal that azo drug production never matched demand, and that hospitals in the 1940s and 1950s rationed their use, reserving them for cases where early intervention might prevent systemic spread. The archives tell the story of a medication that worked only when infection had not yet become systemic — of treatment always arriving too late.

Hospital records themselves form an archive of architectural and epidemiological experiment. The Berlin Teaching Hospital Project, conducted from 1962 to 1978, produced a comprehensive record of infection outcomes in a purpose-built facility designed around asepsis maximalism principles. Every surgical procedure was documented, every infection recorded with pathogenic species identified, every correlation between ward design feature and infection rate calculated. This dataset, held at the hospital and at the Institute for the History of Bacteriology, became the empirical foundation for The Architecture of Prevention: Hospital Design and Infection Outcomes, the standard reference for clean ward construction worldwide.

The International Serum Registry, established in 1975, maintains records not of patients but of biological resources: serum batches, their potency, their donors, their distribution to hospitals across the participating nations. These archives exist to answer a specific practical question — where can sufficient serum of adequate titre be obtained — but they also document the industrial scale of passive immunization. The registry's records show the rise of Specialized serum farms, facilities where herds of horses, sheep, and rabbits were maintained in disease-exposure protocols designed to produce high-titre antibodies. The geographic distribution of these farms, the breeding records of the animals, the seasonal variation in serum yield — all of this was recorded, tracked, and archived as a matter of public health management.

Statistical methods in the Long Sepsis became inseparable from the archive itself. The Kaplan-Meier method, adapted for serum therapy trials where rapid cure was unavailable, required detailed follow-up data collected and preserved for years after treatment. Hospitals began maintaining not case files but survival tables, updating them at fixed intervals, building permanent records of long-term patient outcomes. The Statistical Methods in Clinical Bacteriology and Their Application to Serum Therapy Trials became not just a methodology but an archival standard — a way of organizing and preserving data so that questions asked years later could still be answered.

Newspapers and journals form another substantial archival layer. Public health authorities issued regular infection statistics to press and journal, and these publications accumulated in institutional libraries. The statistical tables in twentieth-century medical journals differ sharply from those of the century before: they measure prevention, compliance, quarantine duration, and serum batch efficacy rather than recovery rates or cure times. The journals themselves are archived, catalogued, and extensively indexed.

What is notably absent from the archives is the kind of record that dominated pre-1928 medicine: detailed clinical narratives following individual patients, descriptions of symptom progression, therapeutic trial and observation. The Long Sepsis archives are sparse in that way — they enumerate but do not describe. A patient might appear in hospital records as a point in a Kaplan-Meier table, a row in a surgical infection tally, or a batch number in a serum distribution ledger, but rarely as a named individual with a documented history. The archives reflect a medical culture that abandoned the hope of understanding individual disease in order to prevent disease in populations.
