František Xaver Dušek

František Xaver Dušek (bapt. December 8, 1731 in Chotěborky - February 12, 1799 in Prague) was a Czech composer and one of the most important harpsichordists and pianists of his time. Dušek was taught on the harpsichord in Vienna by Georg Christoph Wagenseil and established himself around 1770 in Prague as a successful keyboard teacher. Wolfgang Amadeus Mozart was his guest in his Villa Bertramka in Košíře in Prague, and finished at least two of his major works there: in 1787 the opera Don Giovanni and probably also La clemenza di Tito in 1791.
