Erde), resulting in lower quality. By 1776 the Frankenthal porcelain factory had shops in Aachen, Basle, Frankfurt am Main, Livorno, Mainz, Munich and Nancy. The Napoleonic Wars brought an end to the business. Frankenthal was occupied by the French in 1794, who closed the porcelain factory down in 1799. Production had been lower since at least 1790, and models and moulds had been moved to Nymphenburg, which the elector also owned by then, having also become Prince-Elector of Bavaria. The Frankenthal factory was in operation for only 44 years (run for 7 years by the Hannongs, and for 37 by the electoral administration) and is thus the shortest-lived of the major German porcelain manufacturers. It was marked by an unusually numerous succession of directors and principal modellers, although some of the main painters spent a long time at the factory; painted mythological scenes were a Frankenthal speciality. Collections of Frankenthal porcelain may be seen, among other places, in the Reiss Engelhorn Museum in Mannheim, the Kurpfälzisches Museum in Heidelberg, the Historisches Museum der Pfalz in Speyer and the Bavarian National Museum in Munich. Works of the brothers Paul and Johann Hannong are displayed in the Musée des Arts décoratifs, Strasbourg and in the Musée du pain d'épice in Gertwiller.
