In Delft the most visible memorial to commemorate Leeuwenhoek lies in the Oude Kerk (Old Church). In the northern isle set in the tower wall his small monument stands. On the obelisk below his profile are the latin words:

To the fond and everlasting memory of Antony van Leeuwenhoek,
Fellow of the English Royal Society, who, by detecting through diligent
application and scrutiny the mysteries of Nature and the secrets of natural
philosophy by means of microscopes invented and marvellously constructed by himself, and by describing them in the Dutch dialect, has earned the highest approbation of the whole world. Born at Delft 24 October 1632, and died in the same place 26 August 1723.
