Franz Liszt (German: [ˈlɪst]; Hungarian: Liszt Ferencz, in modern usage Liszt Ferenc [ˈlist ˈfɛrɛnt͡s]; 22 October 1811 – 31 July 1886) was a Hungarian composer, virtuoso pianist, conductor, music teacher, arranger, and organist of the Romantic era. He was also a writer, philanthropist, Hungarian nationalist, and 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, Charles-Valentin Alkan, Richard Wagner, Hector Berlioz, Robert Schumann, Camille Saint-Saëns, Edvard Grieg, Ole Bull, Joachim Raff, Mikhail Glinka, and Alexander Borodin.

A prolific composer, Liszt was one of the most prominent representatives of the New German School (German: Neudeutsche Schule). He left behind an extensive and diverse body of work which influenced his forward-looking contemporaries and anticipated 20th-century ideas and trends. Among Liszt's musical contributions were the symphonic poem, developing thematic transformation as part of his experiments in musical form, and radical innovations in harmony.
