Mannheim school
Members of the Mannheim school included Johann Stamitz, Franz Xaver Richter, Carl Stamitz, Franz Ignaz Beck, Ignaz Fränzl, and Christian Cannabich, and it had a very direct influence on many major symphonists of the time, including Joseph Haydn and Leopold Hofmann. (Cannabich, one of the directors of the orchestra after the death of J. Stamitz, was also a good friend of Wolfgang Amadeus Mozart from the latter's visit to Mannheim in 1777 onwards.)
