Pioneering influence and the importance of clean water
During the plague epidemic (1557–1559), around 20 per cent of the population died. Van Foreest believed that the stagnant water in the canals was partly to blame for the plague.

Smallest house in Delft
According to the plaque on the wall of Oude Delft 147, Pieter van Foreest would have lived here in this smallest house in Delft. However, according to the Huizenprotocol, the municipal property register between about 1585 and 1800, he owned the adjacent Oude Delft 145.
