GERRITSZ [GERARD, GERARDUS, GHERRITSZOON van ASSUM].
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.

Tooley.
fl. 1665-79.
Roggeveen was a land surveyor and mathematician by profession, working in Middelburg where the Dutch East and West India Companies maintained collections of hydrographic manuscripts and charts, including Spanish portulans of the West Indies. No doubt through contacts there Roggeveen became interested in navigation and he compiled a pilot book of largescale charts of the West Indies and parts of the American coasts, with a second volume of the coasts of West Africa. These were the first such charts printed in Holland.
