Borngen at Tautenburg. Albert Lortzing (1801-1851), who was born and died in Berlin, was a singer, an actor and later a conductor in Leipzig, Vienna and Berlin. His romantic-comic operas (Zar und Zimmermann, Der Wildschütz, Undine, Der Waffenschmied) became very popular and are full of humor. He mainly wrote the libretti himself.
