Hessel Gerritsz (1581 – September 4, 1632) was a Dutch engraver, cartographer, and publisher active in Amsterdam during the late 16th and early 17th centuries, among the most preeminent Dutch geographers of the 17th century. He was born in Assum, a town in northern Holland in 1581. As a young man he relocated to Alkmaar to accept an apprenticeship with Willem Jansz Blaeu (1571-1638). He followed Blaeu to Amsterdam shortly afterwards. By 1610 he has his own press, but remained close to Blaeu, who published many of his maps. In October of 1617 he was appointed the first official cartographer of the Vereenigde Oost-Indische Compagnie (Dutch East Indian Company) or VOC. This strategic position offered him unprecedented access to the most advanced and far-reaching cartographic data of the Dutch Golden Age. Unlike many cartographers of his period, Gerritsz was more than a simple scholar and showed a true fascination with the world and eagerness to learn more of the world he was mapping in a practical manner. In 1628 he joined a voyage to the New World which resulted in the production of his seminal maps, published by Joannes de Laet in his 1630 Beschrijvinghe van West-Indien; these would be aggressively copied by both the Blaeu and Hondius houses, and long represented the standard followed in the mapping of the new world. Among his other prominent works are a world map of 1612, a 1613 map of Russia by the brilliant Russian prince Fyodor II Borisovich Godunov (1589 – 1605), a 1618 map of the pacific that includes the first mapping of Australia, and an influential 1630 map of Florida. Gerritsz died in 1632. His position with the VOC, along with many of his printing plates, were taken over by Willem Janszoon Blaeu. More by this mapmaker...

Jan Jansson or Johannes Janssonius (1588 - 1664) was born in Arnhem, Holland. He was the son of a printer and bookseller and in 1612 married into the cartographically prominent Hondius family. Following his marriage he moved to Amsterdam where he worked as a book publisher. It was not until 1616 that Jansson produced his first maps, most of which were heavily influenced by Blaeu. In the mid 1630s Jansson partnered with his brother-in-law, Henricus Hondius, to produce his important work, the eleven volume Atlas Major. About this time, Jansson's name also begins to appear on Hondius reissues of notable Mercator/Hondius atlases. Jansson's last major work was his issue of the 1646 full edition of Jansson's English Country Maps. Following Jansson's death in 1664 the company was taken over by Jansson's brother-in-law Johannes Waesberger. Waesberger adopted the name of Jansonius and published a new Atlas Contractus in two volumes with Jansson's other son-in-law Elizée Weyerstraet with the imprint 'Joannis Janssonii haeredes' in 1666. These maps also refer to the firm of Janssonius-Waesbergius. The name of Moses Pitt, an English map publisher, was added to the Janssonius-Waesbergius imprint for maps printed in England for use in Pitt's English Atlas. Learn More...
