Richard Barth
 Richard Barth (5 June 1850 Grosswanzleben Saxony – 25 December 1923 Magdeburg) was a left-handed German violin virtuoso conductor music teacher and composer in the circle of Johannes Brahms. His Ciacona in B minor Op. 21 composed in 1908 is a finely crafted tribute to J.S. Bach's Chaconne in post-Paganini technical and tonal terms.
