full_context: Document 1: Ryszard Wincenty Berwiński: Ryszard Wincenty Berwiński (28 February 1817 in Polwica, Poznań, Prussia – 19 November 1879 in Constantinople, then part of the Ottoman Empire) was a noted Polish poet, translator, folklorist, and nationalist.
Document 2: Wacław Berent: Wacław Berent (Warsaw, 28 September 1878 – 19 November or 22 November 1940, Warsaw) was a Polish novelist, essayist and literary translator from the Art Nouveau period, publishing under the pen names S.A.M. and Wł. Rawicz. He studied Natural Science in Kraków and Zurich, and obtained a PhD in Munich before returning to Warsaw and embarking on a literary career around the turn of the century. Berent became a member of the prestigious Polish Academy of Literature () in 1933.
Document 3: Waldemar Rosenberger: Waldemar Rosenberger, (, Vladimir Karlovich Rozenberger, 1848–1918) from Saint Petersburg, Russia, became director of the Volapük Academy in 1892. Under his leadership, the Academy began to experiment more with the Volapük language. In 1902 the Academy proposed a heavily revised version which was known as Neutral and later Idiom Neutral.
Document 4: Frédéric Chopin: In October 1810, six months after Fryderyk's birth, the family moved to Warsaw, where his father acquired a post teaching French at the Warsaw Lyceum, then housed in the Saxon Palace. Fryderyk lived with his family in the Palace grounds. The father played the flute and violin; the mother played the piano and gave lessons to boys in the boarding house that the Chopins kept. Chopin was of slight build, and even in early childhood was prone to illnesses.
Document 5: 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 6: Frédéric Chopin: Frédéric François Chopin (/ˈʃoʊpæn/; French pronunciation: ​[fʁe.de.ʁik fʁɑ̃.swa ʃɔ.pɛ̃]; 22 February or 1 March 1810 – 17 October 1849), born Fryderyk Franciszek Chopin,[n 1] was a Polish and French (by citizenship and birth of father) composer and a virtuoso pianist of the Romantic era, who wrote primarily for the solo piano. He gained and has maintained renown worldwide as one of the leading musicians of his era, whose "poetic genius was based on a professional technique that was without equal in his generation." Chopin was born in what was then the Duchy of Warsaw, and grew up in Warsaw, which after 1815 became part of Congress Poland. A child prodigy, he completed his musical education and composed his earlier works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising.
Document 7: Frédéric Chopin: In 1827, soon after the death of Chopin's youngest sister Emilia, the family moved from the Warsaw University building, adjacent to the Kazimierz Palace, to lodgings just across the street from the university, in the south annex of the Krasiński Palace on Krakowskie Przedmieście,[n 5] where Chopin lived until he left Warsaw in 1830.[n 6] Here his parents continued running their boarding house for male students; the Chopin Family Parlour (Salonik Chopinów) became a museum in the 20th century. In 1829 the artist Ambroży Mieroszewski executed a set of portraits of Chopin family members, including the first known portrait of the composer.[n 7]
Document 8: 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 9: Bolesław Leśmian: Bolesław Leśmian was born January 22, 1877 in Warsaw, Congress Poland, Russian Empire to a family of Polonized Jewish intelligentsia. He spent his childhood and youth in Kiev, where he graduated from the law faculty of Saint Vladimir University. In 1901, he returned to Warsaw. From there, he set off on a journey to various European cities, including Munich and Paris, where he married a painter, Zofia Chylińska. Heavily influenced by French modernists, Leśmian returned to Warsaw, where he became one of the founders of an experimental "Artistic Theatre". There he also met one of his closest friends, Zenon Przesmycki, with whom he became involved in the publication of "Chimera", an art newspaper.
Document 10: 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 11: 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 12: Frédéric Chopin: Two Polish friends in Paris were also to play important roles in Chopin's life there. His fellow student at the Warsaw Conservatory, Julian Fontana, had originally tried unsuccessfully to establish himself in England; Albert Grzymała, who in Paris became a wealthy financier and society figure, often acted as Chopin's adviser and "gradually began to fill the role of elder brother in [his] life." Fontana was to become, in the words of Michałowski and Samson, Chopin's "general factotum and copyist".
Document 13: Frédéric Chopin: Fryderyk's father, Nicolas Chopin, was a Frenchman from Lorraine who had emigrated to Poland in 1787 at the age of sixteen. Nicolas tutored children of the Polish aristocracy, and in 1806 married Justyna Krzyżanowska, a poor relative of the Skarbeks, one of the families for whom he worked. Fryderyk was baptized on Easter Sunday, 23 April 1810, in the same church where his parents had married, in Brochów. His eighteen-year-old godfather, for whom he was named, was Fryderyk Skarbek, a pupil of Nicolas Chopin. Fryderyk was the couple's second child and only son; he had an elder sister, Ludwika (1807–55), and two younger sisters, Izabela (1811–81) and Emilia (1812–27). Nicolas was devoted to his adopted homeland, and insisted on the use of the Polish language in the household.
Document 14: Jan Lechoń: Leszek Józef Serafinowicz (pen name: Jan Lechoń; March 13, 1899 in Warsaw, Congress Poland, Russian Empire – June 8, 1956 in New York City) was a Polish poet, literary and theater critic, diplomat, and co-founder of the Skamander literary movement and the Polish Institute of Arts and Sciences of America.
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.
