Kreutzer, Rodolphe (1766-1831)
Rodolphe Kreutzer (15 November 1766 – 6 January 1831) was a French violinist, teacher, conductor, and composer of forty French operas, including La mort d'Abel (1810).
He is probably best known as the dedicatee of Beethoven's Violin Sonata No. 9, Op. 47 (1803), though he never played the work, declaring it unplayable and incomprehensible. Kreutzer made the acquaintance of Beethoven in 1798, when at Vienna in the service of the French ambassador, Jean-Baptiste Bernadotte (later King of Sweden and Norway). Beethoven originally dedicated the sonata to George Bridgetower, the violinist at its first performance, but after a quarrel he revised the dedication in favour of Kreutzer.
