Biography:
Cartographer and hydraulic engineer. Cruquius was born in 1678, either on Vlieland or in Delft. His father was a mathematician and surveyor, who worked for the VOC chamber in Delft. In 1698, Nicolaas completed his education as a surveyor and started to make topographical maps, his most important work being a large wall map of Delfland in twenty-five parts. In 1716, he matriculated at Leiden University, where he worked with Herman Boerhaave. He was also active in meteorology. On 19 December 1705, he started to make meteorological measurements in Delft. First, he measured only atmospheric pressure, but soon he expanded his measurements to temperature and wind. From 1733 until his death in 1754, he continued these measurements as employee of the 'Hoogheemraadschap van Rijnland'. His main task for this organization was to manage the hydrology of the polders. Cruquius used his meteorological measurements to persuade the policy makers. He submitted a plan to the States of Holland to establish a meteorological institute. In this he was supported by three professors from Leiden University: Wittichius, 's Gravesande and Lulofs. Although the plan was rejected, Cruquius still played an important role in Dutch meteorology, by being the first to make a sustained and consistent series of meteorological observations. Another novelty was that Cruquius presented his data in graphs. He was also the first one to use symbols to present weather phenomena, such as wind and rain. He also made scientific instruments, such as a standard foot measure (the 'Rijnlandse voet'), made together with Jacob van Werven. In 1724 he was elected Fellow of the Royal Society of London.

Biography:
Meester was an Instrument maker in Leiden, from 1664. He was a master watch maker and inventor. He invented an automatic spirit level (unknown if this instrument was ever made) and sheet iron or tinplate pontoons (a floatation device). He also invented devices to improve watch making. He was well acquainted with Samuel van Musschenbroek and Christiaan Huygens. He matriculated at Leiden University in 1664 and again in 1671. In 1673 he enlisted in the 'Staatse Leger' (permanent professional army of the Dutch Republic) as inspector of the artillery and machines. He was also involved in hydraulics: the building of dikes and measurements of rivers. In 1688 he emigrated to England.
