The point raised as to Müller not having had the smallest foreign assistance may be dismissed as somewhat erroneous. There was Anton Carl Luplau, who was at the Fürstenberg factory for eighteen years, and who came to Copenhagen in 1776; Johan Christoph Ba er, who was born in Nuremberg, and came to Copenhagen in 1768, when he was thirty years old; Peter Heinrich Benjamin Lehmann, who was a native of Hamburg, and came to Copenhagen from the Berlin factory in 1780, and was naturalized in 1781; Carl Fridrich Thomaschefsky, who worked a short time at the factory; and Martin Cadewitz, who served eleven years and died in 1791. But in 1781, of two hundred persons employed at the factory only ten were foreigners. As to whether Müller ever left Copenhagen the Count de Boisgelin adds a footnote: "According to M. Catteau, this was not the fact; we only repeat what the man told us was the case." The work referred to is _Le Tableau des Etats Dannois envisagés sous le Rapport du Mécanisme Social, par Jean Pierre Catteau_, printed in Paris in 1802 in three volumes. It is rather an interesting point, but the evidence is against de Boisgelin, for Müller not only visited Brunswick when he entered into negotiations with Luplau to enter the Danish service, but at a slightly earlier date he made a tour of the German factories--in an assumed name, as some accounts go. That he made good use of his time is amply borne out by the results he achieved in so short a space of time on his return to his native land. There is nothing to detract from the originality and inventiveness of his work. The personality of his genius illuminates the work of the factory. He experienced as many reverses of fortune as did Bernard Palissy, and battled against adverse circumstances with no less indomitable spirit. He conquered technical difficulties, and experimented with clays and bodies and glazes and pigments with hardly less assiduity than did Josiah Wedgwood.
