Mozart's Don Giovanni at the end of 1833, where he took umbrage at the audience's protests about the cost of tickets. His frustration at his everyday duties in Düsseldorf, and the city's provincialism, led him to resign his position at the end of 1834. He had offers from both Munich and Leipzig for important musical posts, namely, direction of the Munich Opera, the editorship of the prestigious Leipzig music journal the Allgemeine musikalische Zeitung, and direction of the Leipzig Gewandhaus Orchestra; he accepted the latter in 1835. Leipzig and Berlin In Leipzig, Mendelssohn concentrated on developing the town's musical life by working with the orchestra, the opera house, the Thomanerchor (of which Bach had been a director), and the city's other choral and musical institutions. Mendelssohn's concerts included, in addition to many of his own works, three series of "historical concerts" featuring music of the eighteenth century, and a number of works by his contemporaries. He was deluged by offers of music from rising and would-be composers; among these was Richard Wagner, who submitted his early Symphony, the score of which, to Wagner's disgust, Mendelssohn lost or mislaid. Mendelssohn also revived interest in the music of Franz Schubert. Robert Schumann discovered the manuscript of Schubert's Ninth Symphony and sent it to Mendelssohn, who promptly premiered it in Leipzig on 21 March 1839, more than a decade after Schubert's death. A landmark event during Mendelssohn's Leipzig years was the premiere of his oratorio Paulus, (the English version of this is known as St. Paul), given at the Lower Rhenish Festival in Düsseldorf in 1836, shortly after the death of the composer's father, which affected him greatly; Felix wrote that he would "never cease to endeavour to gain his approval ... although I can no longer enjoy it". St. Paul seemed to many of Mendelssohn's contemporaries to be his finest work, and sealed his European reputation. When Friedrich Wilhelm IV came to the Prussian throne in 1840 with ambitions to develop Berlin as a cultural centre (including the establishment of a music school, and reform of music for the church), the obvious choice to head these reforms was Mendelssohn. He was reluctant to undertake the task, especially in the light of his existing strong position in Leipzig. Mendelssohn nonetheless spent some time in Berlin, writing some church music such as Die Deutsche Liturgie, and, at the King's request, music for productions of
