certain that he never has cast bells, but left this casting to other bell founders. For the Zuidertoren in Amsterdam, he has probably used the older bells by Jacob Waghevens and Adriaan Steylaert which did service before in earlier days in the Oudekerkstoren also in Amsterdam. He reused them and for the Westertoren the bells were possibly cast at the then in Amsterdam working city bell founder Assuerus Koster. By this Koster there are still the hour and half hour strike clocks from 1636 in Amsterdam Westertoren. The clocks and bells that he supplied according to the archives for these towers will not have been of good quality, for less than thirty years later they were replaced by Jurriaan Spraeckel who worked together with François and Pieter Hemony in many places. Today there is no old clock or carillon by Leeghwater recovered. Bibliography Leeghwater, Jan Adriaensz - het Haarlemmermeerboek, Reprinted in Amsterdam 16 times from 1641.
