"Müller, O. (Wouter) (Dutch). Silversmith, and Medaillist of Amsterdam, whose date of activity is comprised between 1653 and 1688. Bolzenthal calls him "der Meister Müller", and praises much the excellence of the execution of his medals, which, like those of Peter Van Abeele, are embossed and chased, and in high relief. Vide Franks and Grueber, Med. Ill., II, 733. ... Dutch works of reference give this artist's name as Wouter Müller."
