Hans Unger was a German painter who was, during his lifetime, a highly respected Art Nouveau artist. His popularity did not survive the change in the cultural climate in Germany after World War I, however, and after his death he was soon forgotten. However, in the 1980s interest in his work revived, and a grand retrospective exhibition in 1997 in the City Museum in Freital, Germany, duly restored his reputation as one of the masters of the Dresden art scene around 1910.

Bautzen or Budyšin, until 1868 Budissin in German, is a town in eastern Saxony, Germany, and the administrative centre of the district of Bautzen. It is located on the Spree river, is the eighth most populous town in Saxony, and is the seat of Saxony's largest district. Bautzen lies in the bilingual Sorbian settlement area of Lusatia, and is Lusatia's third-largest town after Cottbus and Görlitz, as well as the second-largest town in Upper Lusatia.
