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

full_context: Document 1: 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 2: Alice Halicka: Alicja Halicka was born in Kraków and studied with Józef Pankiewicz there. She moved to Paris in 1912 where she studied at Académie Ranson under Paul Sérusier and Maurice Denis. There she met and married the Cubist painter Louis Marcoussis in 1913. In 1921 she showed cubist work together with her husband at the Société des Artistes Indépendants. She also exhibited her work at the Galerie Georges Petit, Paris (1930-31), Le Centaure, Brussels, the Leicester Galleries, London (1934), the Marie Harriman Gallery, New York (1936), Julian Levy Gallery, New York (1937). Halicka painted in various styles but also produced work in fabric, including Romances capitonnées, and even made set designs for ballets which were performed at the Metropolitan Opera of New York and Covent Garden, London.
Document 3: 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 4: Mexico City: During the 20th century, many artists immigrated to Mexico City from different regions of Mexico, such as Leopoldo Méndez, an engraver from Veracruz, who supported the creation of the socialist Taller de la Gráfica Popular (Popular Graphics Workshop), designed to help blue-collar workers find a venue to express their art. Other painters came from abroad, such as Catalan painter Remedios Varo and other Spanish and Jewish exiles. It was in the second half of the 20th century that the artistic movement began to drift apart from the Revolutionary theme. José Luis Cuevas opted for a modernist style in contrast to the muralist movement associated with social politics.
Document 5: 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 6: 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 7: Tania (artist): Tania (1920, Warsaw, Poland, Tatiana Lewin – 1982, Brooklyn, New York) was a Polish-born, New York based, Jewish American abstract painter, sculptor, collage artist and painter of city walls. She was known by several different married names over the course of her career (including Tania Pollak, Tania Milicevic, Tania Schreiber, Tania Schreiber-Milicevic, Tania Milicevic-Mills, and Tania Mills), but decided as of 1958 to use simply her first name, Tania. She was active in the New York art world from 1949 to 1982, but is perhaps best known for her 13-story geometric wall painting of 1970, which still stands at the corner of Mercer St. & 3rd St. in Greenwich Village, New York. In 1966, she became a founding member of City Walls, Inc., a non-profit organization that commissioned abstract artists to paint walls around New York City, and which (when consolidated with the Public Arts Council in 1977) would later become the Public Art Fund.
Document 8: Terry Winters: Terry Winters (born 1949, Brooklyn, NY) is an American painter, draughtsman, and printmaker whose nuanced approach to the process of painting has addressed evolving concepts of spatiality and expanded the concerns of abstract art. His attention to the process of painting and investigations into systems and spatial fields explores both non-narrative abstraction and the physicality of modernism. In Winters’ work, abstract processes give way to forms with real word agency that recall mathematical concepts and cybernetics, as well as natural and scientific worlds.
Document 9: Jane Freilicher: Jane Freilicher (November 29, 1924 – December 9, 2014) was an American representational painter of urban and country scenes from her homes in lower Manhattan and Water Mill, Long Island. She was a member of the informal New York School beginning in the 1950s, and a muse to several of its poets and writers.
Document 10: 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 11: 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 12: Ilya Schor: Ilya Schor was born in Złoczów (Galicia), in the Austrian Empire, later Poland, in 1904. He came from a deeply Hasidic family. His father Naftali Schorr was a folk-artist, painting colorfully illustrated store signs for local merchants. Ilya Schor first trained as an apprentice in metalcrafts and engraving before enrolling at the Warsaw Academy of Fine Arts in 1930 where he studied painting. In 1937, he was awarded a grant by the Polish government to study in Paris. He exhibited successfully at the Salon d’Automne in 1938. Ilya Schor and his artist wife Resia Schor immigrated to the United States in December, 1941, from Marseilles, via Lisbon, after fleeing Paris in late May 1940. Ilya Schor and Resia Schor had two daughters, born in New York City: artist and writer Mira Schor (b. 1950) and noted literary scholar and theorist, Naomi Schor (1943–2001).
Document 13: 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 14: Ania Walwicz: Ania Walwicz was born in Swidnica, Poland where she spent her childhood, before migrating to Australia in 1963. She attended the Victorian College of the Arts (VCA) in Melbourne. Her writing tends toward an impressionistic, stream of consciousness exploration of inner states. It also exploits 'appropriative' or 'sampling' techniques of production. Apart from publication in numerous anthologies, journals and several books her work has been performed by La Mama Theatre, the Sydney Chamber Choir and more recently set to music by ChamberMade. She has performed her work in France, Japan and Switzerland and currently teaches creative writing at RMIT in Melbourne.
Document 15: 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).
