What job or title did Antonín Dvořák and Giacomo Puccini both have?
Antonín Dvořák Antonín Leopold Dvořák ( ; ] ; 8 September 1841 – 1 May 1904) was a Czech composer. After Bedřich Smetana, he was the second Czech composer to achieve worldwide recognition. Following Smetana's nationalist example, Dvořák frequently employed aspects, specifically rhythms, of the folk music of Moravia and his native Bohemia. Dvořák's own style has been described as "the fullest recreation of a national idiom with that of the symphonic tradition, absorbing folk influences and finding effective ways of using them."
Johann Rudolf Czernin von und zu Chudenitz Johann Rudolf Graf Czernin von und zu Chudenitz (born or baptized on 9 June 1757 in Vienna; died or buried on 23 April 1845 in Vienna) was a k. u. k. Austrian civil servant and theater director. He descended from the old Bohemian noble family Czernin von und zu Chudenitz. He was the son of Count Prokop Adalbert Czernin, who offered Mozart in 1776 a one year's rent, provided he would write some compositions for the Count's orchestra. His sister was Countess Antonie Lützow. And perhaps most important his deceased mother was the sister of Archbishop Colloredo, thus the Count was a nephew of the Salzburg Archbishop.
