Velthuysen (also spelled Veldhuizen, Veldhuyzen) was a well-educated member of the Utrecht city council and a magistrate there. He wrote, mostly in Latin under the name Velthusius, about philosophical and theological subjects. He was also a fervent advocate of Descartes' ideas. He corresponded with Spinoza.

Leeuwenhoek wrote four letters to Velthuysen in 1679, dated May 9, June 13, July 11, and November 14. They discussed Leeuwenhoek's observations of sperm and his ideas about reproduction.
