Natura sanat—nature heals—Dr Heinrich Lahmann and his physiatric sanatorium

Peer-reviewed history-of-medicine/dermatology article devoted to Lahmann and his sanatorium. Identifiers verified 2026-07-08 via PubMed (verify-identifiers) and Crossref (https://api.crossref.org/works/10.1016/j.clindermatol.2025.09.015): authors Wollina U, Hoenig LJ, Parish LC; journal Clinics in Dermatology; 2026;44(2):311-318; DOI and PMID both confirmed. The abstract itself was fetched directly and deterministically via the NCBI eutils efetch endpoint (https://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=pubmed&id=41022271&rettype=abstract&retmode=text, fetched 2026-07-08; see grounding log verify-quotes block for the exact text), which resolved two earlier WebFetch passes that had produced inconsistent/unreliable summaries. The genuine abstract states Lahmann 'attracted patients from Europe and beyond' -- used in this case, in paraphrase, for the international-clientele point -- but it ALSO states he 'died in Dresden in 1941' and 'tried to apply his therapeutic approach to sexually transmitted diseases and chronic dermatitis'. The 1941 death year directly conflicts with three independent authorities that agree on 1905 (the GND authority record, the Neue Deutsche Biographie entry, and the on-artifact inscription confirmed by vision inspection of the photographed memorial plaque, source `lahmann-park-relief-commons`), and no other source in this bundle documents any STI or dermatitis treatment. This case therefore uses ONLY the international-clientele point from this article and does NOT use its death year or its STI/dermatitis claim, which appear to be an error in the published abstract itself (an author/editorial mistake, not a fetch artifact) rather than a fact about the subject of this case.
