Artist, the only non-singing "master” mentioned in Wagner's Mastersingers of Nuremberg (5)
I believe the answer is:
durer
(Other definitions for durer that I've seen before include "Albrecht --, German painter and engraver" , "Renaissance painter" , "German artist, d. 1528" , "Albrecht -, fifteenth to sixteenth century German artist" , "Albrecht -, Ger. artist" .)
