Question: When did Chopin return to the city where Kazimierz Dejmek died?

full_context: Document 1: 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 2: 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 3: Szymon Szurmiej: Szymon Symcha Szurmiej (18 June 1923 − 16 July 2014) was a Polish actor, director, and general manager of the Ester Rachel Kamińska and Ida Kamińska State Jewish Theater in Warsaw. He was a director of the Yiddish Theater of Warsaw. Since July 2004, he has been an honorary citizen of Warsaw. Member of the World Jewish Congress.
Document 4: Mieczysław Czechowicz: Mieczyslaw Czechowicz (September 28, 1930 in Lublin – September 14, 1991 in Warsaw) was a Polish actor. A graduate of Warsaw's State Theatrical Academy (Państwowa Wyższa Szkoła Teatralna), Czechowicz played in numerous films, plays and cabarets. He worked for the National Theatre as well as other Warsaw's theaters. In 1987 he was awarded the Polonia Restituta. As a movie actor, he played in such productions, as Janosik (TV series), Czterej Pancerni i Pies, Lalka, The Tin Drum, and comedies by Stanisław Bareja. Czechowicz's voice is known by almost all kids in Poland, as he voiced the friendly teddy bear in a popular cartoon Miś Uszatek.
Document 5: 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 6: Andrzej Kremer: Andrzej Stanisław Kremer (8 August 1961 in Kraków – 10 April 2010) was a Polish lawyer and diplomat, the Deputy Minister of Foreign Affairs of Poland.
Document 7: Kazimierz Dembowski: Kazimierz Dembowski (3 August 1912 in Strzyżów – 10 August 1942 at Dachau) was a Polish Roman Catholic clergyman and member of the Society of Jesus involved in the religious publishing industry, who shortly after the German invasion of Poland was arrested by the Gestapo, imprisoned at several places of detention, and lastly deported to the Dachau concentration camp where he was murdered in a gas chamber. He is among 122 Polish martyrs whose beatification process was advanced in 2003.
Document 8: 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 9: 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 10: 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 11: 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 12: 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 13: Kazimierz Dejmek: Kazimierz Dejmek (17 May 1924 – 31 December 2002) was a Polish actor, theatre and film director, and politician. During his career he managed the Teatr Nowy in Łódź (now the Kazimierz Dejmek Theatre), the National Theatre, Warsaw, and the Teatr Polski, Warsaw. From 1993 to 1996 he served as Poland's Minister of Culture. In 1989 Dejmek was awarded the Grand Cross of the Order of Polonia Restituta, one of his country's highest honours.
Document 14: Jan Dekert: Jan Dekert or Jan Dekiert (1738 – 4 October 1790) was a Polish merchant of German descent and political activist. Starting in the 1760s, he rose to become one of the most prominent merchants in the Polish capital of Warsaw. He was an activist arguing for more rights for the burghers in the Polish-Lithuanian Commonwealth while opposing Jewish merchants. As the representative of Warsaw, he was elected a deputy to the Sejms of 1784 and 1786, as well as to the Great Sejm (1788–1792). He was the mayor of Warsaw (1789–1790), during which period he organized the Black Procession on 2 December 1789 (a march of burghers who delivered a petition to the king). This was a major step towards the passing of the Free Royal Cities Act enfranchising burghers, as one of the reforms of the Great Sejm and part of the Constitution of the 3rd May, 1791.
Document 15: Emil Pollert: Emil Pollert, born Emil Popper (20 January 1877, Liblice at Mělník – 23 October 1935, Prague) was a Czech opera singer at the National Theatre in Prague, in his time the main representative of bass roles.
