Ca. 1547-99.
Tysk kartograf son till Gerard Mercator (se denne). Född i Leuven, död i Duisburg. Han började som bokhandlarlärling hos förläggaren Arnold Birckman i Köln och arbetade sedan under flera år vid dennes filialer i London och Antwerpen. Men så kastade han sig över geografiska studier och blev sin fars medhjälpare. Världskartan 1587 är det första kända arbetet från hans hand. Senare följde en Europakarta och 1590 en Tysklandskarta. Efter faderns död ansvarade han för utgivningen av dennes atlas.

GERRITSZ [GERARD, GERARDUS, GHERRITSZOON van ASSUM].
Biografiska uppgifter:Hessel 1581-1632.
Gerritsz was apprenticed to W. J. Blaeu as an engraver before starting in business on his own account. He worked closely with Petrus Plancius and his merit may be judged by the fact that he was appointed Cartographer to the Dutch East India Company in preference to Blaeu and subsequently held the same position in a newly formed West India Company. With the new company he came into touch with Johannes de
Laet for whom he prepared a number of new maps of America in the latter's Nieuwe Wereldt published in 1625. His most important early work was a chart showing Henry Hudson's discoveries in his voyage of 1610-11: it is the first to give an outline of Hudson's Bay and indicates Hudson's belief that he had found a way to the North West Passage.
