Primary documents and references underlying the archive
Maison Gabus draws on primary archival, trademark and patent material together with published and specialist references. The list below records the principal sources used across the site, identified by kind. Individual pages carry additional, page-specific citations, linked back here.
CEJARE (Centre jurassien d'archives et de recherches économiques), Saint-Imier — fonds Gabus Frères, Usines Safir (066-GAB), dossiers 066/001 to 066/018. Holds two compiled genealogical charts covering the wider Gabus line, including the Georges-John Gabus / Amélie Guinand marriage: an illustrated tree signed S. Vuille Robbe, Neuchâtel, 1921, and an unsigned, undated “2me Tableau — Descendance de Claude Gabus de Dampmarie”. Both are compiled genealogy rather than registers of acts, and are cited here as such. Holdings also include correspondence, a company brochure, workshop photographs, the 1957 jubilee historique, and Jean-Louis Gabus's Origine et Histoire du Fonds Gabus Frères (1989, also held at MIH). Items cited across the site are 066/006, 066/014, 066/015, 066/017 and 066/018.
