Joseph de Maimieux (1753âÂÂ1820), was a French noble who had emigrated to the Holy Roman Empire at the time of the Revolution, who returned to France in 1797. He invented a kind of universal language system which he revealed in Pasigraphie ou Premiers éléments du nouvel art-science, dâÂÂécrire et dâÂÂimprimer en une langue, de manière àêtre lu et entendu dans toute autre langue sans traduction⦠(Paris, 1797), completed by Pasigraphie et pasilalie, (Paris, an VIII) and Carte générale pasigraphique (1808).
According to Hoefer in his Nouvelle Biographie Générale, he may have helped general Firmas-Périés to write his Pasitélégraphie. Joseph de Maimieux was a member of the Société des observateurs de l'homme.
