This database offers concise information on individuals significant to music and theater history, as featured in Constantin von Wurzbach’s Biographisches Lexikon des Kaiserthums Oesterreich (Biographical encyclopedia of the Austrian empire; 60 volumes, 1856–1923). Between 1999 and 2004, the lexicon’s content was analyzed and excerpted, leading to the creation of this MySQL database in 2013. The database is linked to a PDF version of the Wurzbach Lexicon.
