Louis Spohr (5 April 1784 – 22 October 1859) was a German composer, violinist and conductor.
Born Ludwig Spohr, he is usually known by the French form of his name outside Germany. Sometimes described as "The Forgotten Master", Spohr was once as famous as Beethoven. As a violinist, his virtuoso playing was admired by Queen Victoria. As a composer he ranks as an historic figure in the development of German music drama and whose greatest triumph was in the oratorio. His orchestral writings and chamber works were once considered on a par with Mozart’s.
