Heinrich Ignaz Franz Biber von Bibern was a Bohemian-Austrian composer and violinist. Born in the small Bohemian town of Kremsier (Wartenberg) (Stráž pod Ralskem), Biber worked at Graz and Kroměříž before he illegally left his Kremsier (Kroměříž) employer (Prince-Bishop Carl Liechtenstein-Castelcorno) and settled in Salzburg. He remained there for the rest of his life, publishing much of his music but apparently seldom, if ever, giving concert tours.
