Jan Adriaanszoon Leeghwater
Jan Adriaenszoon Leeghwater (born Jan Adriaenszoon; November 1575 – January 1650) was a Dutch millwright and hydraulic engineer. Biography Leeghwater was born as Jan Adriaanszoon. Only later did he adopt the name Leeghwater, from ''laag water'' or ''low water''. It is not clear exactly how the prevalent spelling of Leeghwater's name came about. Leeghwater himself spelt his name alternatively as Leegwater, Leegh-water, Leeghwater and Leechwater. Official documents of the time also mention Laechwater and Laachwater. Leeghwater, as a hydraulic engineer, was pivotal to land reclamation programs along the flooded coast of the Netherlands.Leeghwater, Jan Adriaansz article, Encyclopedia of Earth, retrieved 2008-03-10 He was involved in the reclamation of the Beemster polder, the first polder in the world created from a lake by draining the water using wind mills. The reclamation of the Beemster was started in 1607 and Leeghwater supervised the milling. Between 1607 and 1635 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Museum De Cruquius
The Museum De Cruquius (or Cruquiusmuseum) occupies the old Cruquius steam pumping station in Cruquius, the Netherlands. It derives its name from Nicolaas Kruik (1678–1754), a Dutch land-surveyor and one of many promoters of a plan to pump the Haarlemmermeer (Haarlem lake) dry. Like many well-educated men of his time, he latinized his name to Nicolaus Samuel Cruquius. During his lifetime the issue of the Haarlem Lake and how to pump it dry was international news, as the following excerpt from the Virginia Gazette on 31 May 1751 illustrates: :"''By a private letter from Rotterdam, we are told, that the Dutch Engineers, in their Plan for draining the lake of Haerlem, proposed to employ 150 mills for three Years, and had computed the Expence at a Million and Half of Florins, but that a German, who had been long employed in the Mines of Hungary and Hartz, had proposed to drain it with 50 machines, in 15 months, at a far less Expence; and that he has been ordered to erect one of ...

Hydraulic Engineers
Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. This area of civil engineering is intimately related to the design of bridges, dams, channels, canals, and levees, and to both sanitary and environmental engineering. Hydraulic engineering is the application of the principles of fluid mechanics to problems dealing with the collection, storage, control, transport, regulation, measurement, and use of water.Prasuhn, Alan L. ''Fundamentals of Hydraulic Engineering''. Holt, Rinehart, and Winston: New York, 1987. Before beginning a hydraulic engineering project, one must figure out how much water is involved. The hydraulic engineer is concerned with the transport of sediment by the river, the interaction of the water with its alluvial boundary, and the occurrence of scour an ...

17th-century Dutch Inventors
The 17th century lasted from January 1, 1601 ( MDCI), to December 31, 1700 ( MDCC). It falls into the early modern period of Europe and in that continent (whose impact on the world was increasing) was characterized by the Baroque cultural movement, the latter part of the Spanish Golden Age, the Dutch Golden Age, the French ''Grand Siècle'' dominated by Louis XIV, the Scientific Revolution, the world's first public company and megacorporation known as the Dutch East India Company, and according to some historians, the General Crisis. From the mid-17th century, European politics were increasingly dominated by the Kingdom of France of Louis XIV, where royal power was solidified domestically in the civil war of the Fronde. The semi-feudal territorial French nobility was weakened and subjugated to the power of an absolute monarchy through the reinvention of the Palace of Versailles from a hunting lodge to a gilded prison, in which a greatly expanded royal court could be more easily k ...
