Christoph Schöner
Christoph Schöner or Schönner was born before 1660 in Vienna but later settled in Augsburg. In 1681 he married the widow of watchmaker Rochus Stressler and ran his own business from 1681 on. Schöner was a very prolific maker and many of his works are now owned by national and international museums and private collections. Schöner died in 1709.
