According to
The New Penguin Dictionary of Music, Antonio Salieri was an Italian composer who lived mainly in Vienna and died there:
Ludwig van Beethoven and
Franz Schubert were amongst his pupils. He intrigued against
Wolfgang A. Mozart, but the idea (as expressed in Rimsky-Korsakov' opera "Mozart and Salieri") that he poisoned Mozart is false. Wrote mainly Italian operas (including a "Falstaff", after Shakespeare's "The Merry Wives of Windsor"), but also 6 Masses, a "Passion" oratorio in Italian, 2 piano concertos, etc.
