1575–1650
Best known as a Dutch millwright and hydraulic engineer, this 17th-century figure became closely associated with the great land-reclamation projects that helped reshape the Netherlands. His name is especially linked with the draining of lakes and the practical ingenuity of the Dutch Golden Age.

by Willem Jan Cornelis van Hasselt, Jan Adriaansz Leeghwater
Born in 1575 and dying in 1650, Jan Adriaansz Leeghwater is remembered as a Dutch millwright and hydraulic engineer. He is most often associated with the use of wind-powered technology in water management, a field that was central to daily life and economic growth in the Netherlands.
Leeghwater's reputation grew through his connection to major drainage and land-reclamation efforts, especially the ambitious work of turning lakes into usable land. That practical expertise made him an enduring symbol of Dutch engineering skill during the 17th century.
He is still remembered not only as a craftsman and builder, but also as a figure tied to the larger Dutch struggle to control water. For readers today, his life offers a window into a time when engineering, landscape, and survival were deeply connected.
