(to which he gave the title "The Szafarnia Courier"), written in a very modern and lively Polish, amused his family with their spoofing of the Warsaw newspapers and demonstrated the youngster's literary gift. 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 annexe of the Krasiński Palace on Krakowskie Przedmieście, where Chopin lived until he left Warsaw in 1830. 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. 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." Travel and domestic success In September 1828 Chopin, while still a student, visited Berlin with a family friend, zoologist Feliks Jarocki, enjoying operas directed by Gaspare Spontini and attending concerts by Carl Friedrich Zelter, Felix Mendelssohn and other celebrities. On an 1829 return trip to Berlin, he was a guest of Prince Antoni Radziwiłł, governor of the Grand Duchy of Posen—himself an accomplished composer and aspiring cellist. For the prince and his pianist daughter Wanda, he composed his Introduction and Polonaise brillante in C major for cello and piano, Op. 3. 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 a duet 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. Chopin's successes as a composer and performer opened the door to western Europe for him, and on 2 November 1830, he set out, in the words of Zdzisław Jachimecki, "into the wide world, with no very clearly defined aim, forever." With Woyciechowski, he headed for Austria again, intending to go on to Italy. Later that month, in Warsaw, the November 1830 Uprising broke out, and Woyciechowski returned to Poland to enlist. Chopin, now alone in Vienna, was nostalgic for his homeland, and wrote to a friend, "I curse the moment of my
