Johann Gottlieb Graun (27 October 1703 – 28 October 1771) was a German Baroque/Classical era composer and violinist, born in Wahrenbrück. (His brother Carl Heinrich was a singer and also a composer, and indeed is the better known of the two.) Johann Gottlieb studied with J.G. Pisendel in Dresden and Giuseppe Tartini in Padua. Appointed Konzertmeister in Merseburg in 1726, he taught the violin to J.S. Bach's son Wilhelm Friedemann. He joined the court of the Prussian crown prince (the future Frederick the Great) in 1732 and was made Konzertmeister of the Berlin Opera in 1740.
