Suspected Daguerreotype Intake for School Athletic Archives: Keep Cased Portraits Intact Before Digitization
School athletic archive daguerreotype intake is the conservator-informed pre-digitization assessment process that examines a suspected cased portrait associated with an early institutional or program figure — a school founder, a program benefactor, or a civic leader whose name is carried by a historic trophy or honor — for the physical and visual characteristics of the daguerreotype format, documents the case exterior, all accessible inscriptions, donor-supplied provenance and rights information, and the observable condition of the sealed cased object, and determines how each item should be stabilized, re-housed if necessary, and routed before any digitization approach is selected. Daguerreotypes — the earliest commercially successful photographic format, produced from 1839 through roughly the late 1850s — are not typical athletic archive content. A school athletic archive that holds one is most likely holding a portrait of a school founder, an early program supporter, or an institutional benefactor whose name appears on the oldest hardware in the collection. The image surface on a daguerreotype is among the most fragile of any photographic format: microscopic particles of mercury-silver amalgam deposited on a highly polished, silver-coated copper plate, held in place only by their fine adherence to the silver surface, with no coating, binder, or protective layer above them. That surface must never be touched, breathed on, cleaned, or exposed to atmospheric contact outside a conservation setting; the sealed assembly of plate, mat, cover glass, and preserver that constitutes the cased daguerreotype is both the photograph and its primary protection.
