Franz Joseph Strauss (26 February 1822 – 31 May 1905) was a German musician. He was a composer, a virtuoso horn player and accomplished performer on the guitar, clarinet and viola. He was principal horn player of the Bavarian Court Opera for more than 40 years, a teacher at the Royal School of Music, Munich, and a conductor.
Strauss is perhaps best known as the father of the composer Richard Strauss, on whose early musical development he was a great influence, steering his son to the classical and away from modern styles. As a composer, Strauss senior is remembered for his works for the horn. They include two concertos and numerous smaller works.
