Freiherr Hans Guido von Bülow (8 January 1830 – 12 February 1894) was a German conductor, virtuoso 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, virtuoso 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. Noted for his interpretation of the works of Ludwig van Beethoven, he was one of the earliest European musicians to tour the United States. Life and career Bülow was born in Dresden into an old and prominent House of Bülow. He was the son of novelist Karl Eduard von Bülow (1803-1853) and his wife, Franziska Elisabeth Stoll von Berneck (1800-1888). From the age of nine, he was a student of Professor Friedrich Wieck (the father of Clara Schumann). However, his parents insisted that he study law instead of music, and they sent him to Leipzig. There he met Franz Liszt, and on hearing some music of Richard Wagner—specifically, the premiere of Lohengrin in 1850—he decided to ignore the dictates of his parents and make himself a career in music instead. He studied the piano in Leipzig with the famous pedagogue Louis Plaidy. He obtained his first conducting job in Zurich, on Wagner's recommendation, in 1850. Bülow had a strongly acerbic personality and a loose tongue; this alienated many musicians whom he worked with. He was dismissed from his Zurich job for this reason, but at the same time he was beginning to win renown for his ability to conduct new and complex works without a score. In 1851, he became a student of Liszt, marrying his daughter Cosima in 1857. They had two daughters: Daniela, born in 1860, and Blandina, born in 1863. During the 1850s and early 1860s he was active as a pianist, conductor, and writer, and became well known throughout Germany as well as Russia. In 1857, he premiered Liszt's Piano Sonata in B minor in Berlin. In 1864 he became the Hofkapellmeister in Munich, and it was at this post he achieved his
