Question: What was Ignaz von Seyfried and Franz von Suppé's nationality?
Context: Franz von Suppé or Francesco Suppé Demelli (18 April 181921 May 1895) was an Austrian composer of light operas and other theatre music.  He came from the Kingdom of Dalmatia, Austro-Hungarian Empire (now part of Croatia).  A composer and conductor of the Romantic period, he is notable for his four dozen operettas. Franz Krenn (26 February 1816 – 18 June 1897) was an Austrian composer and composition teacher born in Droß.  He studied under Ignaz von Seyfried in Vienna, and served as organist in a number of Viennese churches, becoming Kapellmeister of St. Michael's Church in Vienna in 1862.  From 1869 until 1893 Krenn taught harmony, counterpoint and composition at the Vienna Conservatory.  During this time, he appears to have acquired the nickname 'Old Krenn', and is today often described as having been a rather pedantic teacher. Bernhard Bötel (1883–1953) was a German operatic tenor and actor who had an active career in Germany and Austria during the first half of the 20th century.  He made recordings for several record labels during the early years of the recording industry, including His Master's Voice, Odeon Records, Polydor Records, Tri-Ergon, and Vox Records.  On the stage he sang a variety of roles in operas and operettas from leading parts to comprimario roles.  His stage repertoire included Belmonte in Wolfgang Amadeus Mozart's "Die Entführung aus dem Serail", Chapelou in Adolphe Adam's "Le postillon de Lonjumeau", Count Almaviva in Gioachino Rossini's "The Barber of Seville", Daniel in Franz Lehár's "The Merry Widow", the Duke of Mantua in Giuseppe Verdi's "Rigoletto", Gabriel von Eisenstein in Johann Strauss II's "Die Fledermaus", Indigo in Strauss' "Indigo und die vierzig Räuber", Jeník in Bedřich Smetana's "The Bartered Bride", Paolino in Domenico Cimarosa's "Il matrimonio segreto", Pâris in Jacques Offenbach's "La belle Hélène", Pietro in Franz von Suppé's "Boccaccio", and Wilhelm Meister in Ambroise Thomas' "Mignon". Boccaccio is a 1940 Italian operetta film directed by Marcello Albani and starring Clara Calamai, Osvaldo Valenti and Silvana Jachino.  It is based on the 1879 operetta "Boccaccio" by Franz von Suppé.  It was made at the  Scalera Studios in Rome. Pique Dame ("The Queen of Spades") is an operetta in two acts by Franz von Suppé to a German-language libretto very loosely based on Alexander Pushkin's short story "The Queen of Spades".  The author of the libretto is unknown.  "Pique Dame" was a revised version of Suppé's 1862 operetta "Die Kartenschlägerin" ("The Fortune Teller") and premiered in June 1864 at the Thalia Theater in Graz.  The work is primarily known today for its overture which remains a popular concert piece. 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. Boccaccio, oder Der Prinz von Palermo ("Boccaccio, or the Prince of Palermo") is an operetta in three acts by Franz von Suppé to a German libretto by Camillo Walzel and Richard Genée, based on the play by Jean-François Bayard, Adolphe de Leuven, Léon Lévy Brunswick and Arthur de Beauplan, based in turn on "The Decameron" by Giovanni Boccaccio. Leichte Kavallerie ("Light Cavalry") is an operetta in two acts by Franz von Suppé, with a libretto by .  It was first performed in the Carltheater, Vienna, on 21 March 1866. Light Cavalry Overture is the overture to Franz von Suppé’s operetta "Light Cavalry" (German: "Leichte Kavallerie"), premiered in Vienna in 1866.  Although the operetta is rarely performed or recorded, the overture is one of Suppé's most popular compositions, and has achieved a quite distinct life of its own, divorced from the opera of which it originally formed a part.  Many orchestras around the world have the piece in their repertoire, and the main theme of the overture has been quoted numerous times by musicians, cartoons and other media. Albin August Heinrich Emil Swoboda (13 November 1836 – 5 August 1901) was an Austrian operatic tenor, actor, and opera director of German birth.  One of the most famous opera singers of the "Golden Age" of Viennese operetta, he was a leading tenor and dramatic stage actor at the Theater an der Wien from 1859-1878.  He notably appeared in the world premieres of operettas by composers Jacques Offenbach, Johann Strauss II, and Franz von Suppé.  He also appeared in musical comedies and plays in Vienna, and appeared in stage productions of all kinds as a guest artist in theatres in Germany, Hungary, Poland, and Russia.  His son Albin Swoboda, Jr. also had a successful career as an opera singer.  In 1955 a street in the Hietzing district of Vienna was named after him.
