(7622) Pergolesi is an asteroid of the main belt that was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery was made as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory ( IAU code 675) .
It was named on October 16, 1997 after the Italian organist and composer Giovanni Battista Pergolesi (1710–1736), who worked as Kapellmeister in Naples and Rome and whose intermezzo La serva padrona as the forerunner of the opera buffa at a performance in Paris on 1. August 1752 brought the long-lasting discussions about the primacy of French or Italian music to extremes and led to a heated debate which, as the Buffonist dispute, reached into the baroque period .
