Geelkercken, Nicolaes van (c. 1585 - 1656)

Nicolaes van Geelkercken (ca. 1585 - 1656) was a Dutch surveyor, cartographer and publisher active in the early 17th century. He is thought to have begun his work as a cartographer, engraver, and colorist in the shop of Jodocus Hondius. Starting in 1610, he began producing maps to illustrate current conflicts of interest. In order to ensure that his news maps were up to date and accurate, Geelkercken was known to accompany the Dutch army on campaign. He was succeeded in his trade by his sons Isaac van Geelkercken, Jacob van Geelkercken and Arnold van Geelkercken.
