Question: When did Chopin return to the city where Władysław Grzegorz Branicki died?

full_context: Document 1: 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 2: Frédéric Chopin: In 1817 the Saxon Palace was requisitioned by Warsaw's Russian governor for military use, and the Warsaw Lyceum was reestablished in the Kazimierz Palace (today the rectorate of Warsaw University). Fryderyk and his family moved to a building, which still survives, adjacent to the Kazimierz Palace. During this period, Fryderyk was sometimes invited to the Belweder Palace as playmate to the son of the ruler of Russian Poland, Grand Duke Constantine; he played the piano for the Duke and composed a march for him. Julian Ursyn Niemcewicz, in his dramatic eclogue, "Nasze Przebiegi" ("Our Discourses", 1818), attested to "little Chopin's" popularity.
Document 3: Warsaw: One of the most famous people born in Warsaw was Maria Skłodowska-Curie, who achieved international recognition for her research on radioactivity and was the first female recipient of the Nobel Prize. Famous musicians include Władysław Szpilman and Frédéric Chopin. Though Chopin was born in the village of Żelazowa Wola, about 60 km (37 mi) from Warsaw, he moved to the city with his family when he was seven months old. Casimir Pulaski, a Polish general and hero of the American Revolutionary War, was born here in 1745.
Document 4: Nikita Petrovich Panin: Count Nikita Petrovich Panin (Russian: Ники́та Петро́вич Па́нин) (1770–1837), a Russian diplomat, vice-chancellor, State Chancellor 6 October 1799 – 18 November 1800 (acting) and Foreign Minister of Russia. He was a nephew of Count Nikita Ivanovich Panin, son of Petr Ivanovich Panin, son-in-law of Count . Nikita P. Panin plotted the assassination of Paul I of Russia together with Count Peter Ludwig von der Pahlen and the Russo-Neapolitan Admiral José de Ribas. Ribas died before the assassination, which was actually carried out on 23 March [O.S. 11 March] 1801 by a band of dismissed officers headed by General Bennigsen, a Hanoverian in the Russian service, and General Yashvil, a Georgian. The assassination brought Alexander I of Russia to the throne.
Document 5: Władysław Grydziuszko: Following the end of World War II, Władysław Grydziuszko was killed in an accident near Treia, Macerata in Italy on January 29, 1946. During a routine 2nd Armoured Brigade (Poland) training period, Władysław was killed when he fell underneath one of his tanks breaking his spine at the neck. The military considered his death "Killed in Action " (KIA) because he was on duty. His death was instantaneous, and soon afterward there was a memorial service held in his honor. Some 400 soldiers attended his funeral. He was buried in the Polish cemetery in Loreto, Italy on January 30, 1946. The two witnesses of his death was a future Polish Politician named Zygmunt Ostrowski and Michał Matusiewicz.
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: 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 8: Zbigniew Brzezinski: Zbigniew Brzezinski was born in Warsaw, Poland, on March 28, 1928. His family came from Brzeżany in Galicia in the Tarnopol Voivodeship (administrative region) of then eastern Poland (now in Ukraine). The town of Brzeżany is thought to be the source of the family name. Brzezinski's parents were Leonia ("née" Roman) Brzezińska and Tadeusz Brzeziński, a Polish diplomat who was posted to Germany from 1931 to 1935; Zbigniew Brzezinski thus spent some of his earliest years witnessing the rise of the Nazis. From 1936 to 1938, Tadeusz Brzeziński was posted to the Soviet Union during Joseph Stalin's Great Purge, and was later praised by Israel for his work helping Jews escape from the Nazis.
Document 9: 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 10: Christian August, Prince of Anhalt-Zerbst: Christian August, Prince of Anhalt-Zerbst (29 November 1690, in Dornburg – 16 March 1747, in Zerbst) was a German prince of the House of Ascania. He was a ruler of the Principality of Anhalt-Dornburg, then, from 1742, a ruler of the entire Principality of Anhalt-Zerbst. He was also a Prussian "Generalfeldmarschall", but is best known for being the father of Catherine the Great of Russia.
Document 11: 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 12: 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 13: 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 14: Władysław Grzegorz Branicki: Count Władysław Grzegorz Branicki (25 February 1783 in Warsaw – 27 August 1843 in Warsaw) was a Polish nobleman, senator and general in the Russian military. He was a putative grandson of Catherine the Great, through his maternal line.
Document 15: 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.
