[On the usefulness of inscription registries in the health professions for local history of pharmacy: the pharmacists of the arrondissement of Dreux from 1847-1941].

The author calls attention to an unacknowledged source of information for local history of pharmacy in the 19th and 20th centuries: the inscription registries of members of the health professions authorized to practice. He takes as example the arrondissement of Dreux (Eure-et-Loir) from which he draws up a list of pharmacists from 1847, their dates and places of birth, the dates and sites of the granting of their diplomas and the towns in which they practiced.
