Hans von Bülow

Freiherr Hans Guido von Bülow (German: [ˌhans fɔn ˈbyːlo] ; 8 January 1830 – 12 February 1894) was a German conductor, pianist, and composer of the Romantic era. As one of the most distinguished conductors of the 19th century, his activity was critical for establishing the successes of several major composers of the time, especially Richard Wagner and Johannes Brahms. Alongside Carl Tausig, Bülow was perhaps the most prominent of the early students of the Hungarian composer, pianist and conductor Franz Liszt; he gave the first public performance of Liszt's Sonata in B minor in 1857. He became acquainted with, fell in love with and eventually married Liszt's daughter Cosima, who later left him for Wagner.
