What was Ignaz von Seyfried and Franz von Suppé's nationality?
Ignaz von Seyfried Ignaz Joseph Ritter von Seyfried (15 August 1776 – 27 August 1841) was an Austrian musician, conductor and composer. He was born and died in Vienna. According to a statement in his handwritten memoirs he was a pupil of both Wolfgang Amadeus Mozart and Johann Albrechtsberger. He published Albrechtsberger's complete written works after his death. His own pupils included Franz von Suppé, Heinrich Wilhelm Ernst, Antonio Casimir Cartellieri, Joseph Fischhof and Eduard Marxsen.
Wilhelm von Lenz Wilhelm von Lenz (born 20 May 1809 in Riga - died 7 January 1883 in Saint Petersburg) was a Baltic German Russian official and writer. Wilhelm von Lenz was a friend of many mid-century Romantic composers, including Franz Liszt, Frédéric Chopin and Hector Berlioz, Lenz's most important and influential work was an early biography of the German composer Ludwig van Beethoven, entitled "Beethoven et ses trois styles" (1855), written in response to the disparagement of Beethoven by Alexander Ulybyshev in his "Nouvelle biographie de Mozart" (1843). Lenz promoted the idea (already suggested by earlier figures such as François-Joseph Fétis) that Beethoven's musical style be divided into three characteristic periods. Lenz's periodisation, with minor changes, is still widely used today by musicologists in discussing Beethoven's compositions.
