Adolf Čech led performances of operas by a composer who was active during what period?
Adolf Čech Adolf Čech (11 December 184127 December 1903) was a Czech conductor, who premiered a number of significant works by Antonín Dvořák (the 2nd, 5th and 6th symphonies, more than any other conductor; other important orchestral works, four operas, the "Stabat Mater"), Bedřich Smetana ("Má vlast", five operas), Zdeněk Fibich (two operas) and other Czech composers. He also led the first performances outside Russia of two operas by Pyotr Ilyich Tchaikovsky and the Czech premieres of seven operettas by Jacques Offenbach. He was also a bass singer and a translator of opera librettos.
Richard Wagner Wilhelm Richard Wagner ( ; ] ; 22 May 181313 February 1883) was a German composer, theatre director, polemicist, and conductor who is primarily known for his operas (or, as some of his later works were later known, "music dramas"). Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works. Initially establishing his reputation as a composer of works in the romantic vein of Weber and Meyerbeer, Wagner revolutionised opera through his concept of the "Gesamtkunstwerk" ("total work of art"), by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama. He described this vision in a series of essays published between 1849 and 1852. Wagner realised these ideas most fully in the first half of the four-opera cycle "Der Ring des Nibelungen" ("The Ring of the Nibelung").
