Heinrich Ignaz Franz Biber (12 August 1644 (baptised) – 3 May 1704) was a Bohemian-Austrian composer and violinist. Born in the small Bohemian town of Wartenberg (now Stráž pod Ralskem), Biber worked in Graz and Kremsier (now Kroměříž) before he illegally left his Kremsier employer, Prince-Bishop Carl Liechtenstein-Kastelkorn, 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.
