Johannes Brahms (7 May 1833 – 3 April 1897) was a German composer and pianist of the Romantic period. Born in Hamburg into a Lutheran family, Brahms spent much of his professional life in Vienna, Austria. His reputation and status as a composer is such that he is sometimes grouped with Johann Sebastian Bach and Ludwig van Beethoven as one of the "Three Bs" of music, a comment originally made by the nineteenth-century conductor Hans von Bülow. Brahms composed for symphony orchestra, chamber ensembles, piano, organ, and voice and chorus. A virtuoso pianist, he premiered many of his own works. He worked with some of the leading performers of his time, including the pianist Clara Schumann and the violinist Joseph Joachim.

Franz Liszt (October 22, 1811 – July 31, 1886) was a prolific 19th-century Hungarian composer, virtuoso pianist, conductor, music teacher, arranger, organist, philanthropist, author, nationalist and a Franciscan tertiary. Liszt gained renown in Europe during the early nineteenth century for his prodigious virtuosic skill as a pianist. He was a friend, musical promoter and benefactor to many composers of his time, including Frédéric Chopin, Richard Wagner, Hector Berlioz, Robert Schumann, Camille Saint-Saëns, Edvard Grieg, Ole Bull, Joachim Raff, Mikhail Glinka, and Alexander Borodin.
