(7620) Willaert 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 Franco-Flemish organist and composer Adrian Willaert (1485–1562), who from December 12, 1527 held the position of Kapellmeister at St. Mark's Basilica in Venice for the following 35 years and his work in particular through the pupil-teacher generations he founded into the baroque era .
