The scaffolding corn mill in Benthuizen was built in 1772 by Willem Overgaauw. This Willem Overgaauw was also the first miller on this mill and so the mill made its first revolutions on July 18, 1772. It was not unusual at the time to give a mill an animal name, it was probably also done to emphasize a certain characteristic of the mill in question. In Benthuizen the mill was given the name De Haas and this name is a characteristic of speed.
After Willem Overgaauw, many millers have visited the De Haas mill. In 1886 the Koole business became a miller on the mill. It was also he who gave the mill a thorough refurbishment in those years. The mill was put right again around 1890, after the Gräper company discovered that the foundations were rotten. During this work, the mill even stood on three augers for one night! Jacob G. Koole, lzaäk's son, was the last real miller on the mill, because the miller's existence was no longer profitable, he sold the mill in 1924 to the Coöperatieve Maal- en Dorschvereeniging "De Tijdgeest".
The cooperative soon switched to the electric grinding of its regrind (although this was done on a grinding chair in the mill), which meant that the case had been settled for the wind corn mill De Haas.
