Johann Simon Mayr (also spelled Majer, Mayer, Maier), also known in Italian as Giovanni Simone Mayr or Simone Mayr (14 June 1763 – 2 December 1845), was a German composer. His music reflects the transition from the Classical to the Romantic musical era. In 1805 he founded the Bergamo Conservatory. He was an early inspiration to Rossini and taught and advocated for Donizetti.
