How to read this archive

The archive is structured by evidence type. Primary documents anchor every major claim. Contemporary press provides context. Later narratives are included only when clearly labeled. This is a preservation project, not a debate forum.

Primary

Official records, patents, court filings, institutional archives, and original scans.

Contemporary press

19th-century newspapers and journals describing demonstrations and claims.

Interpretation

Secondary accounts and reinterpretations, always labeled as such.

Evidence standard: major factual claims map to a specific provenance entry, with direct institutional access points collected on the Sources page. If a claim cannot be tied to a primary document, it is marked as unconfirmed until documentation is located.

Primary Artifacts (Selected)

A small selection of high-signal visuals from the archive. Each image is backed by a provenance entry in the sources log.
