Franz (October 22, 1811 – July 31, 1886) was a 19th-century Hungarian composer, pianist, conductor, and teacher. As a composer, Liszt was one of the most prominent representatives of the “Neudeutsche Schule” (“New German School”). He left behind an extensive and diverse body of work in which he influenced his forward-looking contemporaries and anticipated some 20th-century ideas and trends.
He also played an important role in popularizing a wide array of music by transcribing it for piano. The Transcendental Études (French: Études d’exécution transcendante), S.139, are a series of twelve compositions for solo piano. They were published in 1852 as a revision of a more technically difficult 1837 series, which in turn were the elaboration of a set of studies written in 1826.
