Question: When did Chopin return to the city where Zygmunt Kubiak was born?

full_context: Document 1: Zdzisław Stieber: Stieber also produced works on the history and development of Polish (1934), Czech (1957), and Slavic in general (1969). Stieber held teaching appointments in Kraków, Lviv, Łódź, and Warsaw. His work in Polish and Slavic philology had a particularly strong influence on the introduction of the structural method in the teaching of phonology at the University of Łódź.
Document 2: Frédéric Chopin: Chopin took the new salon genre of the nocturne, invented by the Irish composer John Field, to a deeper level of sophistication. He was the first to write ballades and scherzi as individual concert pieces. He essentially established a new genre with his own set of free-standing preludes (Op. 28, published 1839). He exploited the poetic potential of the concept of the concert étude, already being developed in the 1820s and 1830s by Liszt, Clementi and Moscheles, in his two sets of studies (Op. 10 published in 1833, Op. 25 in 1837).
Document 3: Jan Maria Gisges: He studied philology of Polish at University of Warsaw. Between 1943 and 1945 he was imprisoned by German Nazis in Auschwitz-Birkenau and other Nazi concentration camps. After the war he lived in Kielce where he worked for the county government. He was also the editor of the regional monthly "Cychry". He published his first poems in official media in 1949. Since 1949 he lived in Warsaw. He was an activist of the Polish Union of Writers.
Document 4: Frédéric Chopin: Possibly the first venture into fictional treatments of Chopin's life was a fanciful operatic version of some of its events. Chopin was written by Giacomo Orefice and produced in Milan in 1901. All the music is derived from that of Chopin.
Document 5: Frédéric Chopin: From September 1823 to 1826 Chopin attended the Warsaw Lyceum, where he received organ lessons from the Czech musician Wilhelm Würfel during his first year. In the autumn of 1826 he began a three-year course under the Silesian composer Józef Elsner at the Warsaw Conservatory, studying music theory, figured bass and composition.[n 3] Throughout this period he continued to compose and to give recitals in concerts and salons in Warsaw. He was engaged by the inventors of a mechanical organ, the "eolomelodicon", and on this instrument in May 1825 he performed his own improvisation and part of a concerto by Moscheles. The success of this concert led to an invitation to give a similar recital on the instrument before Tsar Alexander I, who was visiting Warsaw; the Tsar presented him with a diamond ring. At a subsequent eolomelodicon concert on 10 June 1825, Chopin performed his Rondo Op. 1. This was the first of his works to be commercially published and earned him his first mention in the foreign press, when the Leipzig Allgemeine Musikalische Zeitung praised his "wealth of musical ideas".
Document 6: Frédéric Chopin: Although it is not known exactly when Chopin first met Liszt after arriving in Paris, on 12 December 1831 he mentioned in a letter to his friend Woyciechowski that "I have met Rossini, Cherubini, Baillot, etc.—also Kalkbrenner. You would not believe how curious I was about Herz, Liszt, Hiller, etc." Liszt was in attendance at Chopin's Parisian debut on 26 February 1832 at the Salle Pleyel, which led him to remark: "The most vigorous applause seemed not to suffice to our enthusiasm in the presence of this talented musician, who revealed a new phase of poetic sentiment combined with such happy innovation in the form of his art."
Document 7: Zygmunt Kubiak: Zygmunt Kubiak (30 April 1929, Warsaw – 19 March 2004) was a Polish writer, essayist, translator, propagator of the antique culture, and professor at the University of Warsaw.
Document 8: Frédéric Chopin: At the end of 1831, Chopin received the first major endorsement from an outstanding contemporary when Robert Schumann, reviewing the Op. 2 Variations in the Allgemeine musikalische Zeitung (his first published article on music), declared: "Hats off, gentlemen! A genius." On 26 February 1832 Chopin gave a debut Paris concert at the Salle Pleyel which drew universal admiration. The critic François-Joseph Fétis wrote in the Revue et gazette musicale: "Here is a young man who ... taking no model, has found, if not a complete renewal of piano music, ... an abundance of original ideas of a kind to be found nowhere else ..." After this concert, Chopin realized that his essentially intimate keyboard technique was not optimal for large concert spaces. Later that year he was introduced to the wealthy Rothschild banking family, whose patronage also opened doors for him to other private salons (social gatherings of the aristocracy and artistic and literary elite). By the end of 1832 Chopin had established himself among the Parisian musical elite, and had earned the respect of his peers such as Hiller, Liszt, and Berlioz. He no longer depended financially upon his father, and in the winter of 1832 he began earning a handsome income from publishing his works and teaching piano to affluent students from all over Europe. This freed him from the strains of public concert-giving, which he disliked.
Document 9: Wojciech Żukrowski: Wojciech Żukrowski (14 April 1916 in Kraków – 26 August 2000 in Warsaw) was a Polish prosaist, poet, reporter, essayist and literary critic.
Document 10: Frédéric Chopin: Back in Warsaw that year, Chopin heard Niccolò Paganini play the violin, and composed a set of variations, Souvenir de Paganini. It may have been this experience which encouraged him to commence writing his first Études, (1829–32), exploring the capacities of his own instrument. On 11 August, three weeks after completing his studies at the Warsaw Conservatory, he made his debut in Vienna. He gave two piano concerts and received many favourable reviews—in addition to some commenting (in Chopin's own words) that he was "too delicate for those accustomed to the piano-bashing of local artists". In one of these concerts, he premiered his Variations on Là ci darem la mano, Op. 2 (variations on an aria from Mozart's opera Don Giovanni) for piano and orchestra. He returned to Warsaw in September 1829, where he premiered his Piano Concerto No. 2 in F minor, Op. 21 on 17 March 1830.
Document 11: Antoni Gołubiew: Antoni Gołubiew (February 25, 1907 in Vilnius – June 27, 1979 in Kraków), nicknames Goa, Jan Karol Wayda, Jerzy Cichocki, was a Polish historian, writer and a Catholic publicist. He was one of the cofounders of the pre World War II biweekly "Pax". After the war he wrote for the magazines "Znak", "Odra", and "Tygodnik Powszechny". He was also one of the organizers (together with, among others, Czesław Miłosz) of the poetry group Zagary. He is best known as the author of the four volume historical epic "Boleslaw Chrobry" which was written over the whole lifetime of the author. This epic tells the story of the founding and first years of existence of the Polish state.
Document 12: Frédéric Chopin: Chopin seldom performed publicly in Paris. In later years he generally gave a single annual concert at the Salle Pleyel, a venue that seated three hundred. He played more frequently at salons, but preferred playing at his own Paris apartment for small groups of friends. The musicologist Arthur Hedley has observed that "As a pianist Chopin was unique in acquiring a reputation of the highest order on the basis of a minimum of public appearances—few more than thirty in the course of his lifetime." The list of musicians who took part in some of his concerts provides an indication of the richness of Parisian artistic life during this period. Examples include a concert on 23 March 1833, in which Chopin, Liszt and Hiller performed (on pianos) a concerto by J.S. Bach for three keyboards; and, on 3 March 1838, a concert in which Chopin, his pupil Adolphe Gutmann, Charles-Valentin Alkan, and Alkan's teacher Joseph Zimmermann performed Alkan's arrangement, for eight hands, of two movements from Beethoven's 7th symphony. Chopin was also involved in the composition of Liszt's Hexameron; he wrote the sixth (and final) variation on Bellini's theme. Chopin's music soon found success with publishers, and in 1833 he contracted with Maurice Schlesinger, who arranged for it to be published not only in France but, through his family connections, also in Germany and England.
Document 13: Translation: When a historic document survives only in translation, the original having been lost, researchers sometimes undertake back-translation in an effort to reconstruct the original text. An example involves the novel The Saragossa Manuscript by the Polish aristocrat Jan Potocki (1761–1815), who wrote the novel in French and anonymously published fragments in 1804 and 1813–14. Portions of the original French-language manuscript were subsequently lost; however, the missing fragments survived in a Polish translation that was made by Edmund Chojecki in 1847 from a complete French copy, now lost. French-language versions of the complete Saragossa Manuscript have since been produced, based on extant French-language fragments and on French-language versions that have been back-translated from Chojecki’s Polish version.
Document 14: Frédéric Chopin: Four boarders at his parents' apartments became Chopin's intimates: Tytus Woyciechowski, Jan Nepomucen Białobłocki, Jan Matuszyński and Julian Fontana; the latter two would become part of his Paris milieu. He was friendly with members of Warsaw's young artistic and intellectual world, including Fontana, Józef Bohdan Zaleski and Stefan Witwicki. He was also attracted to the singing student Konstancja Gładkowska. In letters to Woyciechowski, he indicated which of his works, and even which of their passages, were influenced by his fascination with her; his letter of 15 May 1830 revealed that the slow movement (Larghetto) of his Piano Concerto No. 1 (in E minor) was secretly dedicated to her – "It should be like dreaming in beautiful springtime – by moonlight." His final Conservatory report (July 1829) read: "Chopin F., third-year student, exceptional talent, musical genius."
Document 15: Jerzy Żuławski: In a twenty-year writing career, from his first book of poems in 1895, at the age of 21, to his final World War I dispatches in 1915, Jerzy Żuławski created an impressive body of work—seven volumes of poetry, three collections of literary criticism, numerous cultural and philosophical essays, ten plays and five novels. He was considered an important and influential intellectual figure in the early years of the 20th century, but a century later, the only creation which has remained in print and assured him literary immortality is "The Lunar Trilogy". Stanisław Lem (1921–2006), renowned as the "most widely read science-fiction writer in the world", contributed an introduction to the 1956 and 1975 editions of the "Trilogy"'s initial volume, "Na Srebrnym Globie" ("On the Silver Globe"), crediting Żuławski's words with inspiring him to become "a writer of the fantastic" and describing the time he spent reading "The Lunar Trilogy" as "one of the most fascinating and life-changing experiences" of his youth.
