Franz Liszt, T.O.S.F. (October 22, 1811 – July 31, 1886), also known as Liszt Ferenc and Franz Ritter von Liszt, was a Hungarian composer, pianist, and teacher. Liszt was especially renowned for his skills as a pianist. His contributions to classical music include the invention of the symphonic poem and the development of thematic transformation. He also transcribed many compositions for piano. He also wrote essays on many subjects, a biography of Frédéric Chopin (who he lived with for a few years), and a book about the Romani people and their music in Hungary. Liszt is probably most famous for composing the 19 Hungarian rhapsodies.
