Period-Standard Poisoning Screener for Historical Deaths
A research tool that analyzes historical death records to see if the symptoms match poisons known at the time.
A research tool that reads a documented historical death account and reports what a competent 1893 toxicologist would have concluded: which poisons fit the described symptoms, whether the era's tests could detect them, and whether the original verdict reflected evidence or the limits of period forensic chemistry.
Concept
A screener for historians of medicine and forensic history. The user pastes a transcribed historical death account — coroner's report, trial transcript, physician's letter, newspaper description — and the tool parses the symptom course, timing, and circumstances, then matches them against the symptomatology, dose ranges, and detection methods documented in the 1893 Lehrbuch der Intoxikationen [0]. Output: (1) which substances a competent 1893 toxicologist would have shortlisted for that symptom course; (2) whether the era's forensic chemistry could have confirmed each — i.e., whether a historical verdict of "natural death" was forced by detection limits rather than evidence; (3) a citation pack to the supporting textbook passages. The tool deliberately reports the period-standard conclusion, not a modern forensic opinion — that restraint is the product.
Why now
[0] is a newly digitized (2026), 816-page standard textbook of intoxications from 1893, owned by Emil von Behring (1854–1917) — evidence it functioned as a working reference of fin-de-siècle clinical medicine. Historians re-examining 19th-century deaths and poisoning trials currently lack a structured, searchable version of period toxicology; the 2026 digitization makes extraction and symptom-matching feasible for the first time. Claims stay modest by design: the tool reconstructs what the era's medicine could and could not establish, which is precisely the question disputed historical cases turn on.

AI assessment
A highly focused research tool that leverages a specific digitized historical text to provide period-accurate forensic analysis for medical historians.
- Evidence strength 5/5
- The idea is directly grounded in a specific, 816-page authoritative textbook from 1893, providing a concrete knowledge base for the tool's logic.
- Market pull 3/5
- The target users are a niche group of academic historians and curators; while the urgency is high for specific research projects, the total addressable market is small.
- Novelty & moat 2/5
- The idea is a direct application of the same dataset and mechanism as the 'Poison-Plot Anachronism Checker,' shifting the user from fiction writers to historians.
- Feasibility 5/5
- Building a RAG-based system or a structured database from a single digitized textbook to match symptoms is a straightforward technical task.
- Wedge clarity 5/5
- The wedge is exceptionally sharp: reconstructing the specific conclusions of an 1893 toxicologist for historical death accounts.
- Simplicity / focus 5/5
- The product is a single-purpose screener with a clear input and output, avoiding any platform-creep.

Who benefits
The home institution of this very digitization and a leading institute for pharmacy history; the screener converts its 2026 scan into a usable research instrument for studying period toxicology.
- Katherine Watsonindividual
A historian of 19th-century English poisoning cases and forensic medicine; a period-standard symptom-and-detection screener directly supports her reassessment of historical poisoning verdicts.
- Wellcome Collectionorganization
Its library and funding programs support medical-history research on historical deaths and forensic medicine; the screener gives its researchers a structured period baseline instead of scattered primary sources.
- Deutsches Apotheken-Museum (Heidelberg)organization
A museum of pharmacy history with toxicology exhibits; the tool's citation packs and substance shortlists feed exhibit content on period poisons and their detection.
- Max Planck Institute for the History of Scienceorganization
Historians of forensic science there could use it to systematically reassess what 19th-century toxicology could and could not prove in contested cases.
