French violinist, of German extraction, born at Versailles, his father being a musician in the royal chapel. Rodolphe gradually became famous as a violinist, playing with great success at various continental capitals. It was to him that in 1803 Beethoven dedicated his famous violin sonata (op. 47) known as the “Kreutzer.” Apart, however, from his fame as a violinist, Kreutzer was also a prolific composer; he wrote twenty-nine operas, many of which were successfully produced, besides nineteen violin concertos and chamber music. He died at Geneva in 1831.
