Rodolphe Kreutzer (16 November 1766 6 January 1831) was a French violinist, teacher, conductor, and composer of forty French operas. Kreutzer was born in Versailles, and was initially taught by his father, who was a musician in the royal chapel, with later lessons from Anton Stamitz. He became one of the foremost violin virtuosi of his day, appearing as a soloist until 1810. He was a violin professor at the Paris Conservatoire from its foundation in 1795 until 1826. He was co-author of the Conservatoire's violin method with Pierre Rode and Pierre Baillot, and the three are considered the founding trinity of the French school of violin playing. For a time, Kreutzer was leader of the Paris Opera, and from 1817 he conducted there too.
