Task: Question Generation
Input (English): Passage: Kateřina's health gradually worsened and in the spring of 1859 failed completely. Homeward bound, she died at Dresden on 19 April 1859. Smetana wrote that she had died "gently, without our knowing anything until the quiet drew my attention to her." After placing Žofie with Kateřina's mother, Smetana spent time with Liszt in Weimar, where he was introduced to the music of the comic opera Der Barbier von Bagdad, by Liszt's pupil Peter Cornelius. This work would influence Smetana's own later career as an opera composer. Later that year he stayed with his younger brother Karel, and fell in love with Karel's sister-in-law Barbora (Bettina) Ferdinandiová, sixteen years his junior. He proposed marriage, and having secured her promise returned to Gothenburg for the 1859–60 winter. The marriage took place the following year, on 10 July 1860, after which Smetana and his new wife returned to Sweden for a final season. This culminated in April 1861 with a piano performance in Stockholm, attended by the Swedish royal family. The couple's first daughter, Zdeňka, was born in September 1861.Meanwhile, the defeat of Franz Joseph's army at Solferino in 1859 had weakened the Habsburg Empire, and led to the fall from power of von Bach. This had gradually brought a more enlightened atmosphere to Prague, and by 1861 Smetana was seeing prospects of a better future for Czech nationalism and culture. Before deciding his own future, in September Smetana set out on a concert tour of the Netherlands and Germany. He was still hoping to secure a reputation as a pianist, but once again he experienced failure. Back in Prague, he conducted performances of Richard III and Wallenstein's Camp in the Žofín Island concert hall in January 1862, to a muted reception. Critics accused him of adhering too closely to the "New German" school represented primarily by Liszt; Smetana responded that "a prophet is without honour in his own land." In March 1862 he made a last brief visit to Gothenburg, but the city no longer held his interest; it appeared to him a provincial backwater and, whatever the difficulties, he now determined to seek his musical future in Prague: "My home has rooted itself into my heart so much that only there do I find real contentment. It is to this that I will sacrifice myself.".
